Valves - Diaphragm & Pinch Valves |

Diaphragm valves are excellent for controlling the flow of fluids containing suspended solids. Diaphragm valves are available in two basic forms: weir type and straight through types. The weir design is best for general use applications or for tough corrosive and abrasive services. The straight through type can be used in situations where the flow direction changes within the system.
Pinch valves have a flexible elastomer body that can be pinched closed, cutting off flow. Pinch valves are full bore, linear action valves so they can be used for isolation or throttling service. They can effectively control the flow of both abrasives and corrosives, as there is no contact between metal parts and the transport media. | ||
WM Diaphragm Valve A wide selection of body materials coupled with a variety of highly developed rubbers and synthetics for the diaphragm enable the valve to handle the widest possible range of duties.

WM Fire Hydrant Diaphragm Valve The SFV Soft Seated Fire Valve is designed for fire fighting service for use on hydrants. The mechanism is totally enclosed thus preventing contamination from the elements.

WM Pinch Valve The WM Pinch Valve is ideal for controlling the flow of corrosive or abrasive slurries, powders and granular material and is equally efficient when handling gases and viscous liquids.
