Singer Valve - Model EPC -Single Process Controller
The EPC is a single process loop controller designed to complement the Singer Model 2SC-PCO Dual Solenoid Control Valve. Range of application is dependent on the process variable (feedback) transmitter used, which includes (but not limited to) common automatic control valve functions with conventional pilots.

Model EPC controller reads and compares the process feedback (process variable) 4 to 20 mA signal to the desired setting (set-point) 4 to 20 mA signal. Model EPC then accurately positions the valve to bring the process variable towards the set-point until they coincide.
- Simplified loop process controller with advanced P.I.D. implementation
- Quick configuration for any single process application such as flow and pressure
- Capable of remote 4 to 20 mA SCADA process set-point adjustment
- IP65 (NEMA 4) front panel sealing, 1/4 DIN package scalable readouts with super bright LCD
- Capable of local control of model 2SC-PCO dual solenoid valves for single process
EPC Single Process Controller
- The controller shall be a Singer Valve model EPC Controller, powered by 100 VAC to 240 VAC 50 / 60 Hz source. The controller shall come complete with configuration buttons and solid state construction with internal chassis capable of being removed for inspection.
- The controller shall accept a continuous process variable (feedback) 4 - 20 mA signal and a continuous set-point (command) 4 - 20 mA signal. The dual solenoid valve shall be positioned by the controller to bring the process variable towards the set-point.
- The controller shall have a built-in, adjustable, advanced P.I.D. optimization for accuracy.
- Deadband, zero, and span of 4 - 20 mA signal shall be easily adjusted via push buttons.
- The controller shall have a readout for valve operation.
- Prior to shipment, the controller shall undergo full function and operational tests.
