Pneumatic Control Valves – UHP / 90K

This category includes normally closed (N/C) pneumatic control valves designed for ultra-high-pressure (UHP) waterjet systems up to 90,000 psi. These valves are essential components for precise and reliable control of high-pressure water flow in industrial waterjet cutting applications.

The valves are engineered for use with KMT PRO-series waterjet systems and similar UHP installations, where safe and accurate on/off control of the cutting water is critical. Being normally closed, the valve remains shut in its default state and only opens when pneumatic air pressure is applied, providing a fail-safe solution in the event of air loss or system shutdown.

Typical applications

  • Waterjet cutting heads and CNC waterjet systems

  • Industrial UHP waterjet installations

  • Replacement and maintenance of KMT 90K systems

Key features

  • Designed for ultra-high pressure up to 90K psi

  • Pneumatic actuation for fast and reliable response

  • Normally closed (N/C) design for increased operational safety

  • Compatible with KMT PRO I, PRO II, and PRO III systems

  • Available with service kits and spare parts for long service life
