Product Overview

The CLA-VAL D22-138-L21/P9: Position Control Valve 4-20 mA / P9 with D22 Electronic Controller is a programmable control valve designed for direct acting opening/closing or regulating parameters such as pressure, flow, or reservoir level. The CLA-VAL CPC-34 motorized pilot, controlled by a 4-20 mA signal, manages the valve position using hydraulically assisted technology. Its regulation is customizable, following a fully user-programmable profile and rules. The P9 option provides an important manual override in case of power shut-off. As part of the CLA-VAL SERIES D22 programmable Control Valves, it automatically adjusts valve regulation according to customized, predefined rules. The combination of precise, field-proven, CLA-VAL electronically actuated hydraulic pilots and the CLA-VAL D22 Electronic Controller allows for advanced regulation while maintaining full hydraulic control. CLA-VAL SERIES D22 valves can connect to the CLA-VAL Link2Valves web platform for remote valve diagnostic and control. This valve offers simple, reliable, and accurate operation, contributes to system efficiency, and aids in pipe break prevention.
