USED KMT 10189553

The KMT 10189553 is a High-Pressure (HP) Normally Open (N/O) Pneumatic Actuator Assembly designed for use in 60,000 PSI (60K) waterjet cutting systems. This component serves as the bleed-down / dump valve actuator on the cutting head, functioning in its open (flowing) state by default and requiring applied air pressure to close and initiate a cut. Upon loss of air pressure, the valve automatically opens to safely release any stored high-pressure water. It is a direct OEM KMT part used across a wide range of KMT Streamline and Classic Series 60K waterjet machines.
