P.K. Saunders invented and patented the Weir Type Diaphragm Valve over 60 years ago. Saunders diaphragm valve designs and materials are superior in handling abrasive, corrosive, slurry and thick coagulating fluids. Diaphragm valves are ideal for shutoff and flow control of liquid and gas applications.

Weir Type A Diaphragm ValveType A Weir
The original Weir Type general purpose diaphragm valve offers smooth flow and simple operation in any position. Its design provides excellent shut-off and flow control characteristics. Offered in a wide selection of body materials, linings, diaphragms, and operators.

Straight Thru Diaphragm ValveStraight Thru
The Straight Thru diaphragm valve handles abrasive and corrosive slurries, thick coagulating fluids, and a wide variety of suspended solid materials. The straight, full open bore design facilitates cleanout rods, brushes and "pigs".

High Flow Diaphragm ValveHigh Flow
The High Flow diaphragm valves offers higher flow capacity than other valves. There are no pockets to collect debris and when the valves is fully open, the diaphragm stays completely out of the flow passage resulting in smooth, unobstructed flow with minimum pressure drop at maximum flow.
