Bucher WUVPB-1.../WUVPU-1.../WUVPZ-1... technology data
The WUVPB-1 / WUVPU-1 / WUVPZ-1 series of electrically operated pre-controlled sliding valve pressure limiters NG 10 are used for DC type bores. They can replace the WUVP-1-10 series products. They are pre-controlled with a sliding valve main stage. The higher pressure p1 (pressure limitation) and the lower pressure p2 (a second pressure or circulation pressure) can be continuously adjusted and switched independently of each other at the pressure setting without the need to access the seals. The WUVPB-1 is mainly used for low pressure differential values (ON / OFF) for pressure-relieved circulation control. The reduced pressure differential values can reduce the oil temperature rise and thus reduce the energy costs for the user. The WUVPU-1 is fitted with a damping piston, which provides cushioned opening to prevent unnecessary pressure shocks. The WUVPZ-1 is mainly used for 2-stage pressure control applications (HI / LO).
