MISCELLANEOUS HYDRAULIC VALVES

CHECK VALVE

In the check valves flow is free in one direction and blocked in the reverse one.

2 WAYS LIMIT DEFLECTING VALVE

DOUBLE PILOT OPERATED CHECK VALVE

Pilot check valves are used to block the cylinder in both directions. Flow is free in one direction and blocked in the reverse direction until pilot pressure is applied.

SINGLE PILOT OPERATED CHECK VALVE

These valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in the reverse direction until pilot pressure in applied.

HOSE BURST VALVE CARTRIDGE

These valves are used to prevent the actuator uncontrolled descent in case when hose is broken. In case of sudden flow increase (reaction flow), the valve *is operated blocking the flow.

SINGLE OVERCENTER VALVE

These valves are used to control actuator’s movement and block in one direction in order to enable the following functions:- under control descent of a load: load’s weight doesn’t carry it away as the valve prevents any cavitations of the actuator - limited maximum pressure in case of shocks created by loads, overloads or sudden manoeuvrings (load control with opened centre distributor).

DOUBLE OVERCENTER VALVE

These valves are used to control actuator's movement and block in both directions in order to enable the following functions:- load under control descent: load's weight doesn't carry it away, as the valve prevents any cavitations of the actuator - limited maximum pressure in case of shocks created by loads, overloads or sudden manoeuvrings (load control with opened centre distributor).

PILOTED CHECK VALVE 6

The modular pilot check valve are designed to be mounted under any solenoid valve provided that it complies with the CETOP standards.

ADJUSTABLE MAX. PRESSURE VALVE

The relief valve is used to limit pressure in a hydraulic circuit at a certain setting value. When this pressure setting is reached, the valves opens allowing pressure relief in order not to exceed this setting.

SAFETY VALVE

DUAL CROSS RELIEF VALVE

Made up by 2 relief valves with crossed outlet, this valves are used to block pressure to a certain setting in both ports of an actuator/hydraulic motor. They represent the ideal solution both to provide protection against sudden pressure shock and to adjust at different pressure values the 2 ports of any hydraulic circuit.

SEQUENCED VALVE

Sequence valve is used to feed 2 cylinders in sequence: it provides flow to the secondary circuit when a primary circuit function has been completed reaching the pressure setting. The valve allows free return flow. It's ideal for circuits with low pressure in the secondary actuator, as the pressures add to *one another.

MODULAR SAFETY VALVE

SINGLE PILOT OPERATED CHECK VALVE

These valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in the reverse direction until pilot pressure is applied. Thanks to their high pilot ratio and to a delay locking device, these valves are suitable to avoid vibrations in circuits with heavy loads.

90° FLOW REGULATOR VALVES AND COMPENSATED

This valve is used to adjust flow speed of actuators in one direction and allow free flow in the reverse one. If these are not compensated by pressure, flow adjustment will depends on oil pressure and viscosity. High adjustment sensitivity.

SHUTTLE VALVE

This valve is used to select higher pressure value between two pressure lines, excluding the other one.

2 WAY FLOW DIVIDER/COMBINER

SPECIAL VALVES

THROTTLE VALVE

This valve is used to adjust flow speed of actuators in one direction and allow free flow in the reverse one. As pressure compensation is not provided, flow adjustment depends on pressure and oil viscosity.

ADJUSTABLE MAX. VALVE WITH WHEEL

The relief valve is used to limit pressure in a hydraulic circuit at a certain setting value. When this pressure setting is reached, the valves opens allowing pressure relief in order not to exceed this value.
