The normally closed (N/C) cutting valve assembly is a critical safety and control component in abrasive waterjet cutting systems. Designed to remain closed when not actuated, it ensures controlled on/off water flow and immediate shut-off in the event of air or power loss.
Technical details:
-
Function: High-pressure on/off control of the waterjet stream at the cutting head
-
Valve type: Normally closed (N/C) pneumatic cutting valve
-
Configuration: Supplied without nozzle tube, allowing reuse of existing nozzle components
-
OEM reference: 20454354
Benefits:
-
Fail-safe normally closed design for improved operator safety
-
Fast response and reliable sealing under extreme pressure
-
Designed for high cycle life in abrasive waterjet environments
This assembly is ideal for maintenance, replacement, or upgrades of cutting head valve systems where precise and safe control of high-pressure water flow is required.
-
Actuation: Pneumatic
-
Operating pressure: Suitable for ultra-high-pressure waterjet systems (typically up to 60 kpsi, system-dependent)
-
Application: Directs high-pressure water to the nozzle during cutting cycles
-
Compatibility: Commonly used in KMT / IDE-style cutting head assemblies and compatible waterjet systems
