Overview
The Aqualon 12735 – ADO Rebuild Kit – Replaces OMAX 322536 provides the internal components required to service the Adjustable Dump Orifice (ADO) valve. The ADO controls low-pressure bypass flow during startup, shutdown, and transitions into cutting pressure. This kit replaces the core seating, sealing, and stem-support components that wear during normal operation, helping restore consistent low-pressure control and predictable valve behaviour.
What’s Included
The following components are used to rebuild the internal sealing and seating areas of the ADO valve.
Aqualon numbers are included where verified:
Tapered Seat (OMAX 322512) Aqualon 12777

Items without an Aqualon equivalent do not appear in your cross-reference list and cannot be assigned.
Purpose / Why It Matters
The ADO valve modulates low-pressure water flow to create a stable transition before the pump reaches full cutting pressure. As the internal seats, seals, and guiding surfaces wear, the valve can develop bypass leakage, unstable low-pressure control, or delayed pressure rise. Rebuilding the valve with Aqualon 12735 restores the sealing geometry and internal support elements required for smooth and predictable operation.
Compatibility
Aqualon 12735 replaces OMAX 322536 for Adjustable Dump Orifice assemblies that require this OEM rebuild kit. No additional compatibility claims are made.
When to Replace / Service Indicators
Water leakage from the ADO body
Unstable low-pressure behaviour
Slow transition from dump to cutting mode
Visible wear on seats, seals, or stem components
Scheduled ADO service intervals
Common Uses
Routine ADO maintenance
Corrective rebuild following leakage or sticking
Restoring stable bypass control prior to high-duty operation
Why Choose Aqualon
Aqualon components are manufactured to meet the functional requirements of the OEM parts they replace. The Aqualon 12735 rebuild kit restores the internal sealing and seating elements of the ADO valve, supporting accurate low-pressure modulation and dependable system performance.
