Automatic Control Valves

D900 Direct Membrane Valve

Direct-acting membrane main valve for control applications.

Product Description

The D900 is a diaphragm-operated main valve body with a flat-face seat geometry, providing a different flow characteristic from the rubber-lined A900 cone seat. The flat-seat design offers lower headloss at high opening and is preferred for high-flow and constant-flow applications. Compatible with the full range of P-series pilots for pressure, flow and level control duties.
