Characterized Control Valves

E Series Characterized Control Valves

The Chemline E Series Characterized Control Valves provide extremely precise flow control of aggressive fluids. Valves flow characteristics (Cv vs. lift) follow theoretical linear or equal percentage curves through the entire range of stem travel. This is accomplished with precision made replaceable seats and plugs in a wide variety of Cv values. The Teflon bellows shaft seal provides almost frictionless stem movement and provides over 10 years of maintenance-free operation on aggressive chemical services.
