Description
Overcenter valve acting in lineUse
This valve is used to control movement and lock the actuator in one direction and made the following functions:
* controlled descent of the load does not carry it by its own weight, 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 closed-center circuit). It is insensitive to back pressure and is therefore used where normal overcentre not work properly to load control
Materials and characteristics
Body: steel
Internal parts: hardened and ground
Seals: BUNA N standard
Tightness: minor leakage
Mounting
Connect V1 and V2 to, C1 to the free flow side of the actuator and C2 to the actuator side where you want the seal. Assembly is in line. The setting of the valve must be at least 1.3 times higher than the load pressure to allow the valve to close even when subjected to the pressure corresponding to the maximum load.
