Special Features:

Solenoid pilot 2-position, differential pilot return; 4-way valve, 1/2 inch npt ports, side-ported

Properties:

A valve designed to distribute the input power to the individual circuits and to maintain the pressures in these circuits at a preset level above which pressure compensation between the individual circuits may be effected. In case of pressure drop at the input or a lowering of the pressure of one circuit below a present value, the circuits not affected are kept at their protected minimum pressures. Excludes valves (1), safety relief. See also valve (1), relay, air pressure valve (1), brake pneumatic.
