The Bucher 3W/2P Valve (P00679-D) is the directional cartridge for the Bucher PM-3530 4-way pump assembly. It's a drop-in OEM replacement that restores precise control to one of the pump's two double-acting circuits — no adapters, no re-plumbing, ORB seals included.
When should I replace the 3W/2P valve?
Replace when one of the PM-3530's two circuits has lost crispness — drift under load, sluggish response, or audible chatter. Because the 4-way pump runs two independent circuits, you can lose one valve while the other keeps working, so don't assume the pump is fine just because the boom still moves.
