Plastic Diaphragm Valves

Our diaphragm valves are made for tough flow control jobs—especially with liquids that carry solids. They give you accurate shut-off and regulation, even in demanding setups.

Available in PVC, CPVC, PPH, and PVDF, with manual or pneumatic actuation. Sizes range from ½" to 4". Choose from flanged, socket, or true union designs to match your system.

They’re reliable, low-maintenance, and built to handle dirty or corrosive flows without clogging.
