What is CPVC Diaphragm Valve?

CPVC Diaphragm Valves are on-off throttle valves that operate in both directions. They are used to regulate the area through which media can enter and exit the valve, thus changing its speed and velocity.

The valves are used in pharmaceutical filling systems and have the advantage of having 150 mil life opening and closing times at 3 bar operating pressure. Liquid sampling, biological systems, labs and other initiatives all use it.

In optical media and other applications demanding small and light weight dispense valves, CPVC Diaphragm Valves offers drip-free coating and uniform shot-to-shot bonding.

The innovative design of CPVC Diaphragm Valve removes trapped air and bubbles. They are 60% smaller and 70% lighter than traditional dispense valves, which means less maintenance and wear on robotic arms compared to semi-automatic and automatic machines.

CPVC Diaphragm Valves are ideal for analytical chemistry and clinical diagnostics and meet the demands of the most demanding gas flow applications.
