The CLA-VAL CPC 138-L21: Position Control Valve 4-20 mA is designed as a direct-acting valve for opening/closing or regulating pressure, flow, or level. It allows for simple remote changing of the valve set-point via a 4-20 mA analog input, making it suitable for applications where the process variable is monitored separately and a SCADA or similar remote control system provides valve control. The CLA-VAL SERIES CPC valves, including this model, combine the precise control of field-proven CLA-VAL hydraulic pilots with a simple electronically actuated motor. These valves include a hydraulic pilot and an integral controller that accepts a remote set-point command input to make smooth adjustments to the pilot. It offers simple, reliable, and accurate operation, functioning completely automatically.
