For heavily loaded trailers used in conjunction with trucks, it is important to have a high-quality braking system. In it the principle of work both hydraulic, and pneumatic can be applied. It is important to use a high-quality relay valve on a car trailer, because a reliable connection affects the safety of the vehicle.

The functionality of a relay valve

The main task of the node is to control the brakes on the connected trailer. Activation occurs when the pressure value in the main pipeline has fallen below the minimum allowable level.

In practice, there are two types of construction: single-wire and two-wire. For both options, there are common elements that are characteristic of all types of DT Spare Parts brand Relay Valve:

1. a pair of valves;
2. set of connecting heads;
3. control steam valve;
4. single control valve.

The valves responsible for manipulating the brake system send the compressed gas volume to the consumers of the system from the intake source. The work of consumers can occur both autonomously from one another, and in parallel.
