Mecline VRC25 Soft Start Compensated Unloader Valves. The unloader, hydraulically compensated, decreases pressure peaks when opening the gun re-establishing gradually the setted-up pressure avoiding overloads to all the system. Pressure gradual increase at gun opening reduces back stroke to the minimum. Reactivation of by-pass from 40 to 50 Bar (4 to 5 MPa/580–725psi) this allows longer reactivation times of the unloader in by-pass mode also in case of small gun leaks. Hexagonal check valve for a better smoothness. Regulation lock for minimum and maximum pressure in the knob version. Body with inner housing of O-ring in the outlet for a higher resistance.
