USE AND OPERATION
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). The A type is different in the connections position and the pilot ratio
 
MATERIALS AND FEATURES

Body	Zinc plated steel
Internal Parts	Hardended and ground steel
Seals	Buna-N
Standard Tightness	Minor leakage
Standard Settings	320 Bar

Valve setting must be at least 1:3 times more than load pressure in order to enable the valve the close even when undergone to the maximum load pressure.
 
APPLICATIONS
Connect V1 and V2 to the pressure flow, C1 to the free flow side of the actuator and C2 to the actuator’s side you want the flow to be blocked. In-line mounting.
 
ON REQUEST
