Description

The RPCE2-* are two-way or three-way proportional flow control valves, with pressure and temperature compensation, for subplate mounting. These valves are used for flow rate control in hydraulic circuit branches and for speed control of hydraulic actuators. The valves are available in three flow control ranges: two with progressive gain up to 72 l/min and the third with differential gain of 30 l/min. To ensure correct valve operation, maintain a minimum pilot control flow rate of 2 l/min with minimum pressure of 20 bar. Piloting can be internal, with inlet of oil from line E, or external from a line with 1/4” BSP connection on the pilot body. Drainage is always external and must be connected directly to the tank without backpressure by means of subplate connection Y (OR Ø35) or by means of a line (1/4” BSP coupling) on the pilot body. The three-port version RPCE2-70-T3 allows flow control to the circuit by dumping the exceeding flow to the tank. Maximum pressure in the circuit is limited by means of a manual adjustment relief valve which operates on the compensator pilot. They can be controlled directly by a current-controlled power supply, or by an electronic card, to be order separately.

Key Features

• Direct-acting high flow servo valve • ISO 6263-07 mounting standard • Max flow up to 100 l/min • Robust electrical control up to 0.85 A
