Product Name: Bronze Ring for Yongda Waterjet

Description:
This component is a bronze backup ring (also referred to as a brass ring or anti-extrusion ring) used in the high-pressure sealing assemblies of Yongda waterjet cutting systems . It is a precision-machined, rigid ring typically made from high-strength bronze or brass material. The ring acts as a mechanical support component placed adjacent to an elastomeric seal (O-ring) within a seal groove. Its primary engineering function is to provide a rigid barrier that prevents the softer O-ring material from extruding into the clearance gaps under extreme pressure. This ensures the integrity of the primary seal under ultra-high pressure conditions (typically up to 60,000 PSI / 4,137 bar).

Applications:

• Used as an anti-extrusion backup ring for O-rings in high-pressure check valves, on/off valve (water switch) assemblies, and sealing head cartridges.

• Fits into specific seal grooves within the valve body or cylinder head to provide critical support.

• Compatible with standard Yongda waterjet intensifier pumps and the on/off valve assembly (water switch) .

Features:

• High-Strength Material: Constructed from corrosion-resistant bronze or brass to provide excellent mechanical strength and prevent deformation under pressure.

• Precision-Machined: Manufactured to tight tolerances for a proper fit within the seal groove and against mating surfaces.

• Anti-Extrusion Design: Engineered to fill the extrusion gap between the O-ring and the gland wall, preventing the softer seal from being forced into the gap under ultra-high pressure.

• Split Design: Often features a split or angled cut for easy installation over shafts or into bores without special tools.

Maintenance:

• Always Replace with Seals: This is a consumable wear component. Always replace the bronze backup ring whenever the associated O-ring or primary seal assembly (e.g., water switch maintenance kit) is replaced . Do not reuse a ring that shows signs of compression set, splitting, or deformation.

• Inspection: During valve overhaul or pump rebuild, inspect the ring for cracks, uneven wear, or damage caused by high-pressure extrusion.

• Lubrication: Apply a thin layer of high-pressure grease to the ring during installation to prevent galling and ensure proper seating.

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before disassembling the valve or pump.
