A screw-in, cartridge style, direct acting, 3-way pressure compensated flow control valve. The flow rate of this valve in the 1 to 3 flow path is largely independent of the system pressure or in the the bypass-way and is determined by the dimension of a calibrated orifice. The FRP0.S10 is a priority type regulator, delivering the pump flow to port 3 first, then bypassing excess to port 2. All ports may be fully pressurized. Flow out of priority port 3 may vary based on input flow amount, particularly with lower temperatures and increased fluid viscosities. The valve cannot be adjusted for variable flow output. Free flow in the 2 to 1 path is allowed and not pressure compensated.
