Product Overview

The CLA-VAL CPC 138-L21/P9: Position Control Valve 4-20 mA / P9 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 many applications where the process variable is monitored separately and a SCADA or similar remote control system provides valve control. The P9 option provides an important manual override in case of power shut-off. As part of the CLA-VAL SERIES CPC, these Electronic Actuated Pilot control Valves combine precise control of field-proven CLA-VAL hydraulic pilots with a simple electronically actuated motor. The CLA-VAL SERIES CPC valves include a hydraulic pilot and integral controller which accepts a remote set-point command input to make smooth adjustments to the pilot. It offers simple, reliable, and accurate operation, functioning completely automatically.
