Pneumatic Valve Repair Kit | UHP Normally Open (NO), 90K | HJ-20477518


Keep your ultra-high-pressure waterjet system operating at peak efficiency with the UHP Pneumatic Valve Repair Kit, Normally Open (NO), 90K | HJ-20477518, engineered to restore the performance and sealing integrity of pneumatic control valves used on 90,000 PSI (6,200 bar) intensifier pumps. This HJ-20477518 Pneumatic Valve Repair Kit is designed as a complete maintenance solution for rebuilding worn pneumatic valve assemblies, helping eliminate internal leakage, inconsistent valve actuation, pressure loss, and unnecessary downtime.

This HJ-20477518 Pneumatic Valve Repair Kit contains all of the critical sealing and wear components required during routine maintenance of the normally open pneumatic valve assembly. Replacing these wear items at recommended service intervals helps maintain accurate valve response, reliable high-pressure water flow, and maximum cutting performance while extending the service life of your waterjet system. The HJ-20477518 kit includes O-rings for the normally open actuator, valve seat, brass backup ring, stainless steel backup ring, valve stem, and seal components required to service both the valve and actuator.
