Description

The RPCER1 is a two-port proportional flow control valve with feedback, pressure and temperature compensated. For subplate mounting. The position feedback on the flow throttle allows to obtain characteristics with extremely low hysteresis and high repeatability. This valve is used for flow rate control in hydraulic circuit branches or for speed control of hydraulic actuators. It is available in five flow rate control ranges up to 25 l/min. It must be controlled by an external electronic card, type EDM-J (catalogue 89255), to be order separately.

Key Features

• Servo-proportional control with LVDT • Excellent flow repeatability and low hysteresis • Pilot control for higher performance • Optimized for open and closed loop systems
