When the actuator is triggered, the pressure on the valve stem is released, allowing it to move freely and open the valve. Once the actuator is released, the spring-loaded mechanism returns the valve stem to the closed position. There are several different types of quick release valves, each with its own unique design and functionality.
The relay valves control the flow of air between the reservoirs and the brake chambers, allowing the driver to apply and release the brakes. The brake chambers convert the air pressure into mechanical force, which then applies the brake shoes against the brake drum or disc, resulting in the vehicle’s deceleration or stopping.
Ball valves are perhaps the most widely used type of quick release valve. They consist of a spherical ball with a hole in the center that allows fluid or gas to flow through. When the actuator is triggered, the ball rotates 90 degrees, allowing the hole to align with the flow path and open the valve.
Normally closed relief valve A forces fluid to the accumulator and the circuit. Pressure increases as fast as the pump fills the accumulator. When the accumulator and circuit reach set pressure of 3000 psi, pilot pressure opens relief valve A and unloads the pump to tank. Fig. 18-28. Unloading relief valve in an accumulator circuit.
A time delay or a flow meter with a flow switch energizes the solenoid on the relief valve to load the circuit. Deenergizing the normally open solenoid-operated relief valve unloads the pump any time to reduce power consumption, heat buildup, and noise. The system relief valve is normally located near the pump outlet on a typical hydraulic unit.
The control signal may come from a rheostat, a programmable controller, or a computer. Purchase an infinitely variable relief valve as an assembled unit or pipe one remotely. In each case, the pilot head relief controls maximum pressure, while the servo or proportional valve only sets a lower pressure.
