DOROT 29-50F

Diaphragm-actuated, 3-way Spring-loaded, Differential Pressure-reducing, Polymeric Pilot Valve

DOROT 29-50F, is a Diaphragm-actuated, 3-way Spring-loaded, Differential Pressure-reducing, Polymeric Pilot Valve, designed for control of differential pressure-reducing hydraulic valves.
Operation principle
The pilot valve operates as a selector between the common port and the two other ports. The pilot valve will vent, pressurize or lock the hydraulic valve chamber, as a factor of the relation between the regulated pressure and the adjusted preset value.
