Flow control proportional valves

RPCED1 - two-way proportional flow control valve, CETOP 03, with thermal and pressure compensation; and a standard ISO 6263 (CETOP RP 121H) mounting interface.

Normally, used for flow rate control in hydraulic circuit branches or for speed control of hydraulic actuators. The 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 electronic control units, for the full exploitation of the valve's capabilities.

Max flow: up to 25 l/min.

RPCED1-*/T3 - 3-way proportional flow control valve, CETOP 03; with pressure, and temperature compensation, and a standard ISO 6263 (CETOP RP121H) mounting interface.

RPCED1-*/T3 controls the flow supply of the circuit by releasing the excess oil flow via line T directly to the tank. The valve's flow rate can be controlled, proportionally to the current, supplied to the solenoid.

The valve can be controlled directly from a power supply unit or by the corresponding electronic valve control unit for the full exploitation of the valve's capabilities.

Max flow: up to 25 l/min.

QDE* - proportional flow control valves, with a pressure compensator, and standard ISO 6263-03, or ISO 4401-05 mounting surface. Depending on the application of port P, the valve is available as a two- or three-way.

Usually, this valve is used to control flow in secondary hydraulic circuits or for the control of the speed of hydraulic cylinders.

The valve is controlled directly (from a current-controlled power supply), or with an integrated electronic, which allows the full exploit of the valve's capabilities.

Max flow: up to 80 l/min.
Max press.: 250 bar.

RPCER1 - CETOP 03 pressure and temperature compensating, proportional two-way flow control valve, with a standard ISO 6263 (CETOP RP121H) mounting interface.

RPCER1 - used to regulate the flow in the secondary circuit or to control the speed of the hydraulic drive.
The pressure can be increased continuously by the reference signal supplied to the electronic control unit.
The throttle nozzle's control circuit, which regulates the flow rate, allows hysteresis reduction and high repeatability.

Max flow: up to 25 l/min.

RPCE2-* - CETOP 06 proportional 2 or 3-way flow control valves with pressure and thermal compensation; and a standard ISO 6263 (CETOP RP 121H) mounting interface.

The flow rate is controlled proportionally to the current, supplied to the solenoid. Valves are available in three flow control ranges: two with progressive gain up to 72 l/min, and third with a differential gain of 30 l/min.

The drainage is always external and must be connected directly to the tank, without backpressure using subplate connection Y (OR ø 35) or through a line (1/4” BSP coupling) on the pilot body.

The valve is controlled directly by a current control supply unit, or an electronic control unit, which enables the valve's optimal operation.

The three-way version, RPCE2-70-T3, allows the user to control the flow, whereas the excess flow is directed to the T line. The maximum pressure in the circuit is regulated manually, by a relief valve that operates on the compensator control.
The valve's M version allows unloading the entire flow on the T line, with the minimum pressure drops.

RPCE3-* - CETOP 07 proportional 2 or 3-way flow control valves with pressure and thermal compensation; and a standard ISO 6263 (CETOP RP 121H) mounting interface.

Usually, these valves are used for the flow control in the secondary hydraulic circuits, or to control the hydraulic drives' speed.

The valve is controlled directly by a current control supply unit, or an electronic control unit, which enables the valve's optimal operation.

The flow rate can be increased proportionally to the current, supplied to the solenoid. Valves are available in two flow control ranges of 100 l/min - progressive or differential gain.

The valve is controlled from the inside (by taking the oil from line “E”) or the outside. In the second case, the valve's body has a 1/4 ”BSP connection. The drainage is always external and must be connected directly to the tank, without backpressure using subplate connection Y (OR ø 32) or through a line (1/4” BSP coupling) on the pilot body.

The 3-way version RPCE3-100-T3 allows the user, to control the flow manually while the excess flow is directed to the T line. The maximum pressure in the circuit is regulated manually, by a relief valve that operates on the compensator control.
RPCE3-100-T3 proportional valve is also available in /M version that allows unloading the entire flow on the T line, with the minimum pressure drops.
