The Hemiwedge® Cartridge Valve is an innovative design that incorporates the positives features of ball, gate, plug and high performance valves resulting in a mechanically sealing, tight shutoff valve with a simple operation that provides outstanding longevity and performance in a broad range of applications with virtually no maintenance.

The Hemiwedge® Cartridge valve is a thru-conduit, quarter-turn, mechanically sealing design providing low emissions and quick operation capabilities in critical shutoff applications. The product was initially developed with resilient seats, but for severe services (with particulates or for high temperature) a metal-to-metal seated version has been developed. The metal-to-metal seated version uses the same body and bonnet as the resilient seated version and is factory tested to the tightest leakage criteria in the industry (ISO 5208 Rate B).

The Hemiwedge® Cartridge Valve seals using a hemispherical closure member (Hemiwedge®) that wedges tightly against the seat to provide tight shutoff in either high or low pressures with repeatable zero leakage (resilient seated valves) or incredibly low leakage (metal seated valves).
