This is an off settable pilot pressure control for load pressure controls and without it, it is a standby. With the pilot pressure the pump pressure goes up by means of the DRT 1 or 2. It is used mostly by mobile machinery operations. The main spool is determined while pump pressure is appointed by the means of pilot benefactor.

Transmission Factors DRT1 i= 18.2 DRT2 i= 12.4

Ports B pressure port S suction port L,L1 case drain ports (L1 is sealed) T case drain port (pipe separately to tank) X pilot pressure port

Control data Pilot oil usage estimate of 4.5 L min
