Piston Valve Applications: Braking Systems

M&M Piston actuated valves can be used in a wide variety of applications, in this next series of blog posts we are going to provide some examples of the type of applications that they have been used in and the type of valve that we would recommend for the application.

Piston actuated valves used in braking systems:

Piston valves can be used in braking systems used to check and fill braking systems for industrial vehicles.

The unit is installed in car manufacturing factories where braking system are tested before new cars are sold.

The unit carries out a dry cycle followed by a filling cycle. It automatically checks the system for even very small leakages and fills the fluid risk-free.

The braking fluid is an oil with special properties capable to withstand high temperatures without boiling. 

1^st Stage – Test with vacuum

The unit is connected to the braking system. When the vacuum pump (V) is started, valve (A) opens and creates a –0,2 bar depression inside the empty circuit. This stage is needed to dry test the braking system in case of leakages and prevent air bubbles from forming during filling operations.

2^nd Stage - Filling

Once testing has been completed, valve (A) closes, whereas valve B opens and controls the braking fluid at room temperature from the tank. Pump (P) sends the fluid into the braking circuit at 2 bar pressure 

The valve that we would recommend for this application is:
