Membrane Valve
Silicone Membrane valves ( Diaphragm Valves, Air Diaphragm Valve, Diaphragm Control Valve) consists of a valve body with two or more ports, a diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve is constructed from either plastic or metal.
Originally, the diaphragm valve was developed for use in industrial applications. Later on the design was adapted for use in the bio-pharmaceutical industry by using compliant materials that can withstand sanitizing and sterilizing methods.
Products Description
Silicone rubber diaphragm valves are specially designed valves that are used in a wide range of industries for their excellent sealing capabilities, high flexibility, and resistance to extreme temperatures, chemicals, and pressure. These valves consist of a flexible diaphragm made of high-quality silicone rubber that moves up and down in response to changes in pressure, opening or closing the valve depending on the application.
Silicone rubber diaphragm valves are commonly used in industries such as medical, pharmaceuticals, food and beverage, biotechnology, and chemical processing. In these industries, these valves are used to control the flow of highly sensitive fluids such as acids, alkalies, solvents, or gases that require careful handling and precise control.
One major advantage of silicone rubber diaphragm valves is their ability to operate at high temperatures without distorting their shape or losing their flexibility. This makes them ideal for use in high-temperature applications such as steam handling or in industrial ovens, autoclaves, and furnaces.
Another important advantage of silicone rubber diaphragm valves is that they are highly resistant to chemical attack from a wide range of harsh chemicals such as acids, bases, or solvents. This feature makes them suitable for use in the chemical processing industry, where chemical resistance is critical.
Silicone rubber diaphragm valves are also widely used in the medical and pharmaceutical industries, where they are used to control the flow of sensitive fluids such as blood, saline solutions, or drugs. They are also used to control the flow of gases such as oxygen and nitrogen in medical devices.
Silicone rubber diaphragm valves are versatile, reliable, and long-lasting valves that offer excellent performance in various industries. They are suitable for use in high-temperature and chemical-resistant applications, making them an ideal choice for industries that require highly sensitive fluid control.

Silicone Membrane Valve Manufacturing Process
Today there are some customers asking if it is a good solution that steel plate bonded with glue in the center of the membrane.
and the main function of the steel plate is to make the center surface stiff, but also to make a durable surface.
Watch the followed video, then you'll find out the best solution:
1. Smearing a small amount of glue on the steel/ metal plate
2. Fixing the steel/ metal plate on the mold, then put the silicone material on it.
3. Closing the mold and start the molding process for about 350 seconds.
Membrane Valve Material
Membrane Valves/ Diaphragm Valves can be made from a variety of materials. The material choice is based on the nature of the material handled, temperature, pressure, and frequency of operation. Elastomeric diaphragm materials are highly resistant to chemicals at high temperatures. However, the mechanical properties of elastomeric materials will be weakened at a higher temperature (above 150°F). High pressure can also destroy the diaphragm. Another factor that can affect the diaphragm function is the concentration of the media it will handle. The material may exhibit satisfactory corrosion resistance to certain corrodents up to a specific concentration and/or temperature. Examples of diaphragm material and their specifications can be seen in the chart below.
We can make compression mold tooling, liquid silicone rubber injection molding ( LSR Molding) and produce different shapes translucent elastomeric silicone rubber sealing valves & Gasket in the 0.1 mm thickness range according to customer's designs drawings, samples or ideas etc.
Notes: Silicone Membrane Valve with hook should be made of high tensile elastic silicone materials by three layer mold plates for avoid hook damage when production.
Generally, much softer, much better.
