FAQ for Diaphragm Valves

What is a diaphragm valve?

Diaphragm valves are flow control valves that control or shut off the flow of liquids, gases and slurries by utilizing a diaphragm that is flexible. It offers good sealing properties and is suitable for hygienic and corrosive applications.

What are diaphragm valves used for?

Leak-free and contamination-free flow control is crucial in industries like pharmaceuticals, food and beverage, water treatment, chemical processing, biotechnology, and wastewater treatment, and that's why diaphragm valves are so popular.

What are the advantages of diaphragm valves?

Diaphragm valves provide good sealing, corrosion resistance, low maintenance, ease of operation and reliability. They can also be used to transport abrasive, corrosive and viscous fluids.

What materials are diaphragm valves available in?

Diaphragm valves can be made of PVC, CPVC, PP, PVDF, cast iron, ductile iron, stainless steel, etc. materials. The diaphragm material is typically EPDM, PTFE, NBR or various other elastomers depending on the application.

How does a diaphragm valve work?

The diaphragm valve is a valve that works in the way of the movement of the flexible diaphragm up and down. The diaphragm crushes against the valve seat to prevent a flow. When the diaphragm is lifted, the fluid can flow through the valve.
