Check Valve Flat Washe 201277 High Quality Waterjet Parts Supplier

The Check Valve Flat Washer 201277 is a precision-machined sealing washer designed for use in high-pressure waterjet check valve assemblies and hydraulic intensifier systems. It provides a secure, leak-free interface between critical valve components — such as the valve seat, poppet, and housing — ensuring stable water flow, reliable sealing, and consistent system pressure during continuous operation.

Manufactured from hardened stainless steel, tool steel, or high-performance polymer, the 201277 flat washer offers excellent dimensional stability, wear resistance, and corrosion protection. Each washer is CNC-ground and polished for a smooth surface finish, ensuring even load distribution and perfect contact sealing between mating parts. Its precise geometry minimizes deformation under ultra-high-pressure conditions, maintaining long-term sealing performance up to 60,000 psi (4000 bar).

The Check Valve Flat Washer 201277 is fully compatible with KUNDA, KMT, FLOW, and OMAX waterjet systems, serving as a direct OEM-quality replacement part. It is commonly used in high-pressure check valves, inlet valves, and outlet valve assemblies, where precision alignment and stability are critical to reliable cutting operation.

Ideal for applications in metal fabrication, stone cutting, ceramic machining, and composite material processing, this washer helps extend the life of surrounding components by maintaining consistent sealing force and minimizing valve seat wear.
