On/off Valve 1-13903-2-1-1 Top-inlet Water Jet Cutter Parts

Product Introduction

On/Off Valve 1-13903-2-1-1 is a high-pressure water control valve used in abrasive Waterjet Cutting Systems. It is designed to control the start and stop of ultra-high-pressure water flow between the pump and cutting head during the cutting process. The valve provides stable switching performance, reliable sealing, and fast response speed, helping ensure consistent cutting accuracy and stable system operation in industrial applications.

Is It a Wear Part?

The complete valve assembly is not typically considered a direct wear part. However, internal seals, seats, and needles are consumable components that will gradually wear under repeated high-pressure cycling.

Recommended Inspection

Please inspect or service the valve when:

• Water leakage occurs
• Pressure becomes unstable
• Valve response slows down
• Internal sealing parts show wear
