Product Name: Advantage EP On/Off Valve Kit Extended Life (Part No. 392001-1-2)

Description:
This component is a complete extended-life repair kit for the pneumatic on/off valve (water switch) in Advantage EP series waterjet cutting systems, rated for 94,000 PSI (approximately 6,480 bar) operation . It is designed to restore the valve‘s ability to reliably start and stop the ultra-high-pressure waterjet without leakage.

According to manufacturer documentation, the kit includes the following components :

The “Extended Life” designation indicates upgraded poppet and seal materials for significantly longer service life compared to standard repair kits. The kit is universally 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 when the valve fails to seal properly (water leaks from cutting head when closed) or when valve response is sluggish

• Used during scheduled preventive maintenance to prevent unexpected downtime

• Compatible with Flow universal valves (60k-94k) and Advantage EP systems

Features:

• Extended Life Design: Upgraded poppet and seal materials provide longer service life than standard kits

• Complete Component Set: Contains all consumable parts needed for a full valve rebuild in one kit

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

• Tool Included: Seal ejection tool (190104-1) 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: 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

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

• Scheduled Preventive Maintenance: Regular replacement prevents unexpected downtime and extends valve body life

Installation Guidelines :

• 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 or non-woven fabric 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

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

• 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
