Sun Hydraulics | PPHB-8WN | Valve

Pilot-operated three-way normally open pressure-reducing/relieving main stage with an integral control cavity. The cavity will accept any T-8A pressure control cartridge. The valve reduces a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full flow relief function from port 1 to the tank (port 3). The pilot cartridge’s setting determines the difference in pressure between reduced pressure (port 1) and the tank (port 3).
