Product Description
The HJ WATERJET HP Pneumatic Actuator Assembly, Normally Closed, 60K (HJ-10177855) is a critical control component designed for high-pressure waterjet systems operating up to 60,000 PSI (4,100 bar).
The HJ-10177855 HP Pneumatic Actuator Assembly, N/C uses compressed air to control the opening and closing of high-pressure valves, enabling precise regulation of water flow to the cutting head. In a normally closed (NC) configuration, the valve remains closed by default (no cutting) and opens only when actuated—ensuring safe, controlled operation.
The HJ-10177855 HP Pneumatic Actuator Assembly is widely used across SL-IV, SL-V, and SL-VI intensifier systems and integrates with pneumatic control valves and dump valve assemblies.
The HJ-10177855 HP Pneumatic Actuator Assembly, Normally Closed, 60K include the following parts:
(1) HJ-10176543 Pneumatic Valve Actuator Cylinder, N/C
(1) HJ-20411546 Pneumatic Valve Actuator Piston
