Sanitary valves are easy to clean
In any health and hygiene industry, the importance of how products are manufactured cannot be underestimated. There are many facets to all that is involved in manufacturing in the food or medical industries, everything from regulating flow to maintaining consistent temperatures. Knowing that sanitary valves are a cinch to clean makes life easier.
Sanitary valves have smooth and polished surfaces
This means they will not corrode or rust over time. This is crucial for the industries in which they tend to be used. When bad corrosion occurs, it is often costly. And it can be time-consuming to replace and repair machinery. Many businesses in the food, dairy, or pharmaceutical industries save money by using stainless steel sanitary valves.
They leave no room for germs or particulates
Germs and particulates can embed themselves inside the valves, where bacteria can often grow. Sanitary valves have no crevices – thus, there is no way for germs to find a home.
Sanitary valves all undergo rigorous testing
This is to ensure their strength and reliability. The greatest advantage you will find with a sanitary valve is that they continue to achieve a perfect shutoff even after decades of use.
Sanitary valves can be built with thousands of variations, but are classified into three different types, based on their mechanical motions. The three distinct classes are linear motion, rotary motion, and quarter-turn valves.
Linear Motion Valves utilize a closing member and move in a straight line to allow, stop, or throttle the flow of the medium. Some common examples of linear motion valves are gate, globe, diaphragm, pinch, and lift check valves.
Rotary Motion Valves use a valve-closure member that moves across an angled or cylindrical path. A few of the most common types of rotary motion valves are butterfly, ball, plug, eccentric, and swing check valves.
Quarter Turn Valves are basically rotary motion valves that only require roughly a quarter-turn (or 0 through 90°) stem motion to go from fully open to fully closed position or vice versa.
Of these three distinct valve types, not all are considered sanitary. Remember, sanitary valves must meet special sterile requirements, especially for the valve body and sealing components. The sealing surface of the valve seat must be non-toxic. For example, the material for hard sealing and soft sealing can be stainless steel and rubber, respectively. If we narrow the list down more, the most common types of sanitary valves are sanitary butterfly valves and sanitary ball valves. Other common sanitary valves include sanitary check valves, sanitary solenoid valves, and sanitary diaphragm valves.
Superior hygiene standards: Sanitary grade valves are built to meet strict hygiene standards. Their smooth surfaces and sanitary seals minimize the risk of product contamination, ensuring the integrity and safety of the fluid being processed.
Traceability: In some industries, such as pharmaceuticals, it's important to have complete traceability (the ability to track a product's history, origin, materials, and movement throughout its lifecycle) of all components, including valves. Certain manufacturers provide this information for their sanitary grade valves, which users can request while purchasing.
SIP and CIP compatibility: Sanitary grade valves are designed to be compatible with SIP (Steam-in-Place) and CIP (Clean-in-Place) processes. SIP involves exposing the valve to high-temperature steam to sterilize it. CIP utilizes cleaning solutions and circulation to remove contaminants. The design and materials of sanitary grade valves allow them to withstand these rigorous cleaning and sterilization procedures without compromising their integrity.
Easy cleaning and maintenance: Sanitary grade valves are designed for easy cleaning and maintenance.
Sanitary grade valves can be easily dismantled for cleaning. Some can even be cleaned without disassembly using the CIP technique.
The smooth surfaces allow for a thorough cleaning, minimizing the risk of bacterial growth. Their construction enables quick and efficient maintenance, reducing downtime and ensuring optimal performance.
Compliance with regulatory standards: Sanitary grade valves should comply with standards such as 3A, FDA , and EHEDG.
Versatile options: There are various types of sanitary grade valves, including butterfly valve, ball valve, diaphragm valve, check valves or pressure relief valves, each with its own specific uses and advantages.
The most significant difference between sanitary valves and ordinary valves is that sanitary valves are designed for applications requiring clean or sterile processing. Sanitary valves are commonly used in dairy, food, pharmaceutical, medical, and chemical applications. Standard features include easy cleaning, crevice-free, and polished contact surfaces. Ordinary valves are linear motion valves and are generally used to start, stop, and regulate fluid flow in applications that do not require “food-grade" cleanliness.
Sanitary Valves Vs. Industrial Valves
Strictly speaking, the manufacturing standards for sanitary valves are very high. They are mainly developed for bio-fermentation companies and have very high requirements for the smoothness of the valve runner. Each part of a sanitary valve that will contact fluid must be made of stainless steel—usually 304SS or 316 stainless steel. Such material is non-toxic and non-hazardous, with a clean and smooth surface that doesn't produce corrosion and shedding. With special treatment after manufacturing and processing, sanitary valves are made with superior quality to industrial valves in many ways, such as cleanliness and simple installation. They're widely used in food, medical and other industries.
Another key feature of sanitary valves is that they must be free from crevices, cavities, and sharp corners where bacteria and other foreign matter can accumulate. They also require compatibility with easy cleaning-in-place (CIP) procedures.
There are many different types of sanitary valves, including sanitary stainless steel ball valves, sanitary butterfly valves, sanitary plug valves, sanitary rotary valves, and many more. Each type of sanitary valve serves its own purpose within industrial fluid systems. But they all share a common characteristic—they're built with completely sterile and contaminant-free components to maintain the health and purity of the product that flows through them.
Sanitary Valves Vs. Ordinary Valves
Sanitary valves are used in highly hygienic environments such as pharmaceuticals, food, and daily commodities. Ordinary valves bring precise control to industrial fluid transmission systems, providing diversion, medium, regulation, anti-backflow, shunt, and pressure relief functions. There are already many different types of valves in use across the vast industrial world. With the continuous performance improvements of various technical equipment, more and more valve variations are necessitated every year.
The use of sanitary valves is common in various industries, particularly the food & beverage, and the pharmaceutical industry. The valves are used in applications, which require clean or sterile processing in order to ensure the highest possible levels of sanitation are maintained. Sanitary valves are of various types including ball, diaphragm, and butterfly. They are also used where very low-pressure drop is required. Most popular of them are ball sanitary valves and butterfly sanitary valves.
Ball Sanitary Valves
Sanitary Ball valves which often carry the 3A approval rating are ideal for nearly any application requiring the transfer of consumable liquids and food-related materials. They are known to provide tight shut-off and can be supplied with V-Port characteristics for modulating control. Because of the design of the regulating element, ball valves have a high range-ability. Ball sanitary valves can also be supplied with the optional cavity filled seats, which prevent the media from getting trapped in the seating area.
Modern facilities have advanced many different aspects of the process they count on reliable, sanitary valves, such as sanitary ball or butterfly valves from IPS. We have a wide variety of sanitary valves available to meet different valve requirements.
Butterfly Sanitary Valves
Butterfly sanitary valves are typically used as isolation for larger lines, typically 2" and larger. They are quick opening valves consisting of a metal circular disc of varying materials or coated depending on the application requirements. They pivot at right angles to the direction of flow in the pipe, such that, when rotated on a shaft, they seal against the seats in the valve body. The advantages of using sanitary valves are:
Crevice-free – This is particularly important for the food and dairy industries as crevices are associated with higher levels of germ contamination. Sanitary valves ensure the cleaning is crevice-free. With no crevices in the valve, you are able to prevent hygiene problems.
Easy to Inspect and Clean – Because the food and dairy industries are already busy with other more important things like ensuring the right amounts of product, regulating the flow of the product, and maintaining a consistent temperature, it is crucial that cleaning work is not too cumbersome. Since sanitary valves are typically full port and crevice-free, they are easy to inspect and clean.
Smooth and polished surfaces – Preventing corrosion or pitting is often a costly process for many businesses. Because sanitary valves provide you with a smooth and polished surface, sanitary valves do not undergo the process of corrosion, media buildup, or pitting. Businesses in the food or pharmaceutical industries can save a significant amount of money by using polished sanitary valves.
Factors For Selecting Sanitary Valves!
The world of valves mimics the world of humans. In the human world, there are two types of' jobs that are extremely sensitive and can make a difference of life and death. There are those of soldiers or policemen standing unflinching in harsh environments, and then there are doctors working in highly sterile conditions. When choosing a sanitary valve, it's crucial to conduct a thorough analysis of the medium, process conditions, and control process parameters.
Sanitary Valve distinct design features
Despite the word sanitary in its name, a sanitary valve operates in applications where maintaining a highly clean and sterile environment is critical. Sanitary valves process the media that is used for biological consumption. Hence, the requirement for high cleanliness. Sanitary valves feature a distinct design to enable working in super-clean environments.
Sanitary valves distinct design features of
Absence of crevices or cavities to avoid trapping the media on which bacteria can grow
Wetted surfaces that come in contact with the media are polished
Maximum possible radius size to avoid clinging or entrapment of the media
Butt welds, threads, flanges, and clamps to prevent external contamination
Aseptic design for better cleanliness
Factors impacting sanitary valves selection
The training of a soldier and that of a doctor differ as per the sensitivity of their job. If you apply the criteria of what makes the best soldier for choosing a doctor (and visa versa), there would be a disaster. Along the same lines, the criteria for choosing sanitary valves differ significantly from those to judge other industrial valves.
Body material
Low carbon Stainless steel is the most preferred material for sanitary valves. This is because only steel has the capability to meet the high cleanliness norms set by regulations. Materials such as iron or copper cannot satisfy the sanitary hygiene conditions set for these valves.
Seals
Sanitary valves are generally soft-seated. They use O-rings, seals, and seats made from soft yet abrasion-resistant materials.
Standards
Standards matter all the more for sanitary valves, given they process media meant for human consumption. A number of ASME, MSS, and API standards apply to sanitary valves.
Conclusion
Given the importance of hygiene in sanitary valves, they demand highly polished production in line with health standards. An experienced valve manufacturing expert could be the key to obtaining durable, reliable, and standardized sanitary valves for your application.
