Product Name: Advantage EP On/Off Valve Kit (Extended Life) – Part No. 392001-1

Description:
This component is a complete extended-life repair kit for the on/off valve (water switch) in Advantage EP series waterjet cutting systems rated up to 94,000 PSI (approximately 6,480 bar). The kit is specifically designed for the pneumatic water switch, which controls the start and stop of the ultra-high-pressure waterjet to the cutting head.

The kit contains all the critical consumable components required to rebuild the on/off valve, including the extended-life poppet valve, poppet seal, seal buttress, seal ejection tool, O-rings, and food-grade lubricant. The "Extended Life" designation indicates upgraded materials for longer service life compared to standard repair kits.

This universal kit is compatible with Flow Universal Valves (60k-94k) and serves as a direct OEM replacement for Advantage EP waterjet systems.

Applications:

• Rebuilds the pneumatic on/off valve (water switch) on 94,000 PSI extreme pressure waterjet cutting systems

• Restores leak-free shutoff and crisp valve actuation response when the valve fails to seal properly or water leaks from the cutting head when closed

• Used during scheduled preventive maintenance to prevent unexpected downtime

• Compatible with Flow, H2O Jet, and other standard waterjet systems

Features:

• Extended Life Design: Upgraded poppet and seal materials for significantly longer service life compared to standard kits

• Complete Component Set: Contains poppet landing, extended life poppet, poppet seal, seal buttress, seal ejection tool, O-rings, and food-grade lubricant

• Universal Compatibility: Compatible with Flow Universal Valves (60k-94k) and Advantage EP systems

• Complete Rebuild Solution: All necessary wear components for a full valve overhaul in one kit

• Tool Included: Seal ejection tool facilitates safe removal of old seals without damaging the valve body

• Premium Lubricant: Includes food-grade lubricant (400034-2) for proper seal installation

Maintenance:

When to Replace (Failure Diagnosis):

• Water Leakage from Cutting Head: Visible water dripping from the mixing tube when the valve is supposed to be closed indicates seal or poppet failure requiring immediate kit replacement

• Valve Fails to Open or Close Completely: If the waterjet does not start or stop properly when signaled, internal components are likely worn

• Slow or Sluggish Actuation: Delayed valve response indicates worn seals or degraded poppet material

• Pressure Drop: Inability to maintain rated cutting pressure may indicate valve seal degradation

• Scheduled Preventive Maintenance: Replace on a regular schedule based on operating hours to prevent unplanned downtime

Installation Procedure:

• Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures

• Complete Kit Replacement: When valve wear is detected, replace all components in the kit simultaneously—do not mix new parts with old ones

• Clean Valve Body: Thoroughly clean the valve cavity with a soft cloth to remove debris, water scale, and old seal residue. Do not use sharp tools that could scratch sealing surfaces

• Proper Lubrication: Apply the included food-grade lubricant (400034-2) to seals and O-rings during installation to prevent dry start-up and ensure proper seating

• Component Orientation: Follow the equipment service manual for correct orientation of seals, backup rings, and the poppet within the valve body

• Post-Installation Testing: After reassembly, test at low pressure first, verify no leakage, then gradually increase to full operating pressure before returning to cutting operations

• Use Seal Ejection Tool: Use the included tool (190104-1) to safely remove old seals without damaging the valve body bore
