Rexroth Pump Pilot Valve

An OEM hydraulic control valve used in Flow pump systems to direct pilot pressure and support proper pump shifting/control response. As part of the pump’s hydraulic valve circuit, it helps regulate actuation timing and maintain reliable pump operation under repeated cycling. Replace this valve when troubleshooting sluggish shifting, inconsistent hydraulic response, internal leakage, or valve-related pump control faults.

Service tip: Before replacing the pilot valve, verify clean hydraulic fluid, proper electrical/air actuation where applicable, and free movement of the associated shift valve components. Contamination, sticky spools, or low pilot pressure can cause symptoms that appear similar to a failed pilot valve.
