Proportional Valve Manifold

A manifold component used in the hydraulic control circuit of compatible Flow waterjet pump systems. This assembly helps route and regulate hydraulic flow for stable pump response, controlled pressure behavior, and dependable system operation. Because manifold performance directly affects valve timing, hydraulic stability, and pump control, this part is typically replaced when contamination, leakage, damaged ports, or inconsistent hydraulic response is detected.

Critical note: Before installation, flush the hydraulic circuit and inspect all ports, fittings, seals, and mating valve surfaces for debris or damage. Contamination inside a hydraulic manifold can cause sticking valves, unstable pressure control, or premature wear of connected pump components.
