Pneumatic Actuator Assembly

Pneumatic Actuator (Normally Closed)

This category includes normally closed pneumatic actuators and related components for waterjet cutting systems. Pneumatic actuators are essential parts of a normally closed pneumatic cutting valve and are responsible for converting compressed air into linear motion that opens and closes the valve during cutting operations. The N/C design ensures the actuator remains closed when no air pressure is applied, providing reliable performance and improved safety in high-pressure systems. 

What’s Included in This Category

  • Actuator Assemblies (Normally Closed) – Complete actuators for pneumatic cutting valves.

  • Actuator Cylinders – Pneumatic cylinder components that house the piston and generate motion.  

  • Pistons & Bearing Discs – Internal moving parts essential for actuator operation. 

  • Seals, O-Rings & Snap Rings – Wear parts and maintenance components for long service life. 

  • Spring Kits – Pneumatic spring sets used in actuator assemblies.

  • Air Fittings & Protection Caps – Accessories to support installation and connection to pneumatic systems.

Key Features

  • Normally Closed (N/C) pneumatic actuation for reliable valve control. 

  • Designed for use with pneumatic cutting valves in UHP waterjet systems. 

  • Includes essential mechanical components such as pistons, cylinders, and seals.

  • Built for durability and precision under demanding high-pressure environments. 

Typical Applications

  • Pneumatic actuation for waterjet cutting valves in industrial settings.

  • Service and maintenance of normally closed pneumatic valve systems.

  • Replacement parts for KMT-style pneumatic cutting valves and similar systems.
