Sanitary Diaphragm Valves

A reliable source for Diaphragm Valve information and leading Diaphragm Valve Companies & Manufacturers.

Sanitary valves comply with strict health and safety requirements in the food, beverage, and medical industries. The bodies of sanitary valves are built of stainless steel that complies with strict health regulations. Every component that comes into contact with a liquid, gas, or slurry medium has been mirror polished. They are used in hospitals, pharmaceutical companies, and food processing facilities.Read More…

Sanitary Diaphragm Valves Sanitary diaphragm valves are process flow regulation devices constructed of sterile materials and designed to create an aseptic environment for liquid, gaseous and semi-solid material flows. Like all diaphragm valves, these mechanisms use a membrane made of elastomeric polymers to stop, start and modify the flow and pressure of process streams for a number industrial and commercial manufacturing applications.

However, sanitary valves are also useful in settings with strict health regulations that forbid any tolerance for chemical and physical dangers.

Sanitary Valve

Types of sanitary valves

Sanitary valves are categorized by how they mechanically move. For example, linear motion, rotary motion, and quarter-turn valves are three different classes of sanitary valves.

Linear motion valves enable, halt, or throttle flow using a closing member. Gate valves, globe valves, diaphragm valves, pinch valves, and lift check valves are standard linear motion valves.

Linear Motion Valve

In rotary motion valves, the component that closes the valve travels in an angled or cylindrical route. Some common rotary motion valves are butterfly, ball, plug, eccentric, and swing check valves.

In essence, quarter-turn valves are rotational motion valves that may be turned from fully open to fully closed or vice versa with just a quarter-turn of the stem motion.

Remember that sanitary valves must adhere to unique sterility standards, particularly for the valve body and sealing elements. In addition, the valve seat's sealing surface must be non-toxic. Rubber and stainless steel are suitable materials for hard and soft sealing. The most common sanitary valve types are sanitary ball valves and sanitary butterfly valves. Sanitary check valves, solenoid valves, and diaphragm valves are also used throughout the industry.

Mechanical Sealing Requirements for Sanitary Valves

Sanitary valves must follow strict mechanical sealing specifications. The contact surface must be easy to clean and disinfect. Manufacturers must ensure a fluid transition and flow with no material buildup. Material flowing from the valve shouldn’t be able to escape from the sealing surface.

Applications of a Sanitary Valve

In the food and beverage sector, sanitary valves connect and regulate conveyance pipelines that process fluid and semi-fluid materials.

Sanitary valve material construction requirements vary depending on the type of industrial use. However, the most common material used is stainless steel.

Advantages of Sanitary Diaphragm Valves

  • Sanitary valves have nylon sleeves to reduce friction and simplify the opening and closing process.
  • Sanitary valves are made of food-grade rubber and stainless steel. They are useful for products that are susceptible to external contamination.
  • Sanitary butterfly valve handles are resilient to torque from pulling or wrenching. As a result, they are less likely to fracture.
  • Sanitary valves often have detachable connections for easy repair and cleaning.
  • Sanitary valves must pass rigorous strength and sealing testing.

Disadvantages of Sanitary Diaphragm Valves

  • Ball valves should not be used for continuous throttling.
  • The particles of excess fluids adhere to the surface and could lead to leaks, abrasion, and other issues.
