Use

Valve used to control the movement and blockage of the actuator in one direction, performing the following functions:

• controlled descent of the load that does not escape dragged by its own weight, as the valve does not allow any cavitation of the actuator;
• limitation of the maximum pressure in the event of shocks due to load, overloads or abrupt maneuvers (load control with open center distributor).

The “A” type differs from the “non A” type due to the location of the connections and the piloting ratio.

Mounting

Connect V1 and V2 to the power supply, C1 to the side of the free flow actuator and C2 to the side of the actuator where the seal is desired. The assembly is online.

Schematic Drawing

Use

Valve used to control the movement and the blockage of the actuator in both directions realizing the following functions:

• controlled descent of the load that does not escape dragged by its own weight, as the valve does not allow any cavitation of the actuator
• limitation of the maximum pressure in the event of shocks due to load, overloads or abrupt maneuvers (load control with open center distributor).

The “A” type differs from the “non A” type due to the location of the connections and

the piloting relationship.

Mounting

Connect V1 and V2 to the power supply and C1 and C2 to the actuator to be controlled. The assembly is online.
