Diaphragm Valves

At ValveMan, we've got a wide selection of diaphragm valves that are suitable for sanitary, corrosive, and abrasive applications, where cleanliness and reliability are paramount. Diaphragm valves use a flexible diaphragm to control the flow of your media, with exceptionally tight shutoffs and the usual dead space associated with ball or butterfly valves, allowing for the most uncontaminated closure and easy cleaning. Many industries utilize diaphragm valves, including pharmaceutical, food & beverage, and chemical processing industries. Diaphragm valves are available in a wide choice of body materials, end connections, and actuation methods. If you require assistance in locating another configuration that is not listed, we will be happy to help or locate it if we cannot.

We Carry Diaphragm Valves

This family is built to the application — size, end connection, pressure rating, body and seat material each change the part number, so we spec it with you rather than list every permutation. Tell us where it’s going and a ValveMan specialist will come back with the exact model, current pricing, and availability.
