Hydraulic valveHCZFF 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. Increasing pedal force increases brake port pressure until the pedal force balances the hydraulic feedback force;

Releasing the pedal returns the valve to the released position.
