Model EPC

The PORTER EPC Electronic Proportional Control Valve is an electromagnetically-actuated, proportional control valve designed for use in closed loop flow or pressure control systems. When coupled with a flow sensor or pressure transducer and a proportional electronic controller, the Model EPC is capable of providing steady and precise control of gas flow rates or pressures. The Model EPC is a DC-driven, normally closed valve which includes an elastomeric valve seat to provide bubble-tight shut-off. A broad range of flow coefficients (Cv’s) is available for either flow or pressure control.

The Model EPC is offered with either integral compression fittings for in-line mounting or as a manifold mount version. To allow design and user flexibility, custom configurations in OEM-scale quantities are also available.
