DOROT 31-310, is a Diaphragm-actuated, 3-way Spring-loaded, Multipurpose Metal Pilot Valve, designed for control of pressure-regulating hydraulic valves. The pilot valve operates as a selector between the common port and the two other ports.
Operation principle
The pilot will vent, pressurize or lock the hydraulic valve chamber, as a factor of the relation between the regulated pressure and the adjusted preset value. The 31-310 pilot valve can be implemented for a wide range of hydraulic control functions.
