Flow control proportional valves

Flow control proportional valves

 

RPCED1 - Direct operated flow control proportional valve

The RPCED1 valve is a two-way flow control proportional valve with pressure and thermal compensation, CETOP 03, and mounting interface in compliance with ISO 6263 (CETOP RP 121H) standards

It is normally used for flow rate control in hydraulic circuit branches or for speed control of hydraulic actuators.

Flow rate can be modulated continuously in proportion to the current supplied to the solenoid.

The valve can be controlled directly by a current control supply unit or by means of the relative electronic control units to exploit valve performance to the full.

It is available in five flow rate control ranges up to 25 l/min.

RPCED1-*/T3 - 3-way flow control proportional valve

RPCED1-*/T3 is a three-way flow control proportional valve, pressure and temperature compensated, CETOP 03, with mounting interface in compliance with ISO 6263 (CETOP RP121H) standards.

This valve controls the flow to the circuit, by dumping the exceeding oil flow to the tank.

Flow rate can be modulated continuously in proportion to the current supplied to the solenoid.

The valve can be controlled directly by a current control supply unit or by means of the relative electronic control units to exploit valve performance to the full.

It is available in five flow rate control ranges up to 25 l/min.

QDE* - Flow control compensated proportional valves

The QDE* are a compensated flow control proportional valves, CETOP 05, with pressure compensation and mounting surface according to ISO 6263-03 and ISO 4401-05 (CETOP RP121H), supplied with 2 or 3 way design, depending on the use of port P.

This valve is used for the regulation of the flow in branches of a hydraulic circuit or for the speed control of hydraulic cylinders.

The flow can modulated continuously in proportion to the current supplied by the solenoid

The valve can be controlled directly from a current controlled power supply or with an integrated electronic, which allow to fully exploit the performance of the valve.

QDE* valves are available in two sizes, for 5 flow adjustment ranges of up to 80 l/min.

RPCER1 - Flow control proportional valves with feedback

RPCER1 is a pressure and temperature compensated two-way flow control proportional valve, CETOP 03, with mounting interface in accordance with the ISO 6263 (CETOP RP121H) standards.

The position feedback of the flow rate controlling throttle gives regulation conditions featuring highly reduced hysteresis and high repeatability. 

It is normally used to control the flow rate into an arm of the hydraulic circuit or the speed of the hydraulic actuators. 

The flow rate can be modulated continuously in proportion to the reference signal sent to the electronic control unit. 

It is available in five flow rate control ranges up to 25 l/min

RPCE2-* - Pilot operated flow control proportional valves

The RPCE2-* are two-way or three-way flow control proportional valves with pressure and thermal compensation, CETOP 06, and mounting interface in compliance with ISO 6263 (CETOP RP 121H) standards.

These valves are normally used for flow rate control in hydraulic circuit branches and for speed control of hydraulic actuators.

Flow rate can be modulated continuously in proportion to the current supplied to the solenoid.

The valve can be controlled directly by a current control supply unit or by means of the relative electronic control units which enable optimal valve performance.

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 and minimum pressure of 20 bar.

Pilot control can be internal, with intake 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 ø 35) or by means of a line (1/4” BSP coupling) on the pilot body.

The three-way 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.

RPCE2-70-T3 valve is also available in M version, which allows, by means of an electric control, to unload the total flow with a minimum pressure drop.

RPCE3-* - Pilot operated flow control proportional valves

The RPCE3-* are two-way or three-way flow control proportional valves, CETOP 07, with pressure and thermal compensation and mounting interface in compliance with ISO 6263 (CETOP RP 121H) standards.

These proportional valves are normally used for flow rate control in hydraulic circuit branches and for speed control of hydraulic actuators.

Flow rate can be modulated continuously in proportion to the current supplied to the solenoid.

The valve can be controlled directly by a current control supply unit or by means of the relative electronic control units which enable optimal valve performance.

The valves are available in two flow control ranges of 100 l/min, with progressive gain or with differential gain.

To ensure correct valve operation, maintain a minimum pilot control flow rate of 2 l/min and minimum pressure of 20 bar.

Pilot control can be internal, with intake 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 Ø32) or by means of a line (1/4” BSP coupling) on the pilot body.

The three-way version RPCE3-100-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.

The RPCE3-100-T3 proportional valve is also available in /M version, which allows, by means of an electric control, to unload the total flow with a minimum pressure drop.
