Hydraulic valvePDF01 Hydraulic valve

Designed for hydraulic braking systems of construction machinery and spring-applied, hydraulically released braking systems;

Features a proportional pressure-reducing valve, with output pressure proportional to pedal force for responsive braking and good inching performance;

The single-circuit brake valve can be used with an accumulator and charging valve to provide service braking and emergency power-cutoff braking in open-center, closed-center, and load-sensing hydraulic circuits;

In the released position, the brake port is connected to the tank port. Initial pedal movement closes the tank port to the brake port. Further pedal movement opens the pressure port to the brake port, and increasing pedal force raises brake port pressure until pedal force balances hydraulic feedback force;

Releasing the pedal returns the valve to the released position.
