Dual liquid filling valveDACV Dual liquid filling valve

Designed for hydraulic braking systems of construction and mining machinery;

Features a spool valve design for smooth, stepless pressure control throughout the pressure range. Inverse braking is achieved by reducing the preset pressure. The valve maintains the brake in the fully released position, while spring-applied, hydraulically released brakes provide service braking. Responsive braking and good inching performance;

The inverse 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 work port is connected to the brake port. Initial pedal movement closes the tank port to the brake port. Further pedal movement connects the brake port to the tank port;

Brake line pressure is proportional to pedal position and force;

Releasing the pedal returns the valve to the released position.
