Mechanical Shift Valve with Pilot Valve

The Mechanical Shift Valve with Pilot Valve is a Flow OEM pump valve assembly used to control hydraulic shifting in compatible waterjet pump systems. The integrated pilot valve helps direct the actuation signal that reverses intensifier stroke direction, supporting consistent pressure cycling, stable pump operation, and reliable cutting performance. This assembly is typically replaced when shift timing becomes inconsistent, hydraulic response slows, or valve wear begins affecting intensifier operation.

Critical note: Before installation, inspect hydraulic fittings, electrical or pilot-control connections, and surrounding valve manifold surfaces for contamination or damage. A clean hydraulic circuit and correctly functioning pilot signal are essential for smooth stroke reversal and stable pump pressure.
