CRS 200 Corrosion Resistant Regulator

The CRS 200 regulators are designed for the toughest uses with corrosive gases such as chlorine and hydrogen chloride. Along with it electroless nickel-plated forged brass body for harsh environments, the CRS 200's large Monel nozzle and KEL-F seat reduces the possibility of seat failure. The CRS 200 also features a yoke-style tied diaphragm which further resists seat failure and provides instant response to tough flow demands. The Teflon lining of the stainless steel diaphragm forms a protective barrier to increase regulator life.

A captured vent on the bonnet allows for the remote venting of hazardous gases.
