Seat Stainless Stell 90428 Good Quality Waterjet Parts Supplier

The Seat Stainless Steel 90428 is a precision-machined valve seat designed for high-pressure Waterjet Cutting Systems, Hydraulic Intensifiers, and pump assemblies. It serves as the sealing interface for the poppet or check valve, ensuring leak-free operation, stable pressure retention, and long-term reliability under continuous ultra-high-pressure conditions.

Manufactured from premium-grade stainless steel (typically 17-4PH or 316), the 90428 valve seat delivers excellent strength, corrosion resistance, and wear durability, even when exposed to continuous abrasive water flow and pressure up to 60,000 psi (4000 bar). The sealing surface is CNC-ground and lapped to a mirror finish, allowing precise contact with mating components like the poppet valve, thereby ensuring consistent sealing performance and minimal maintenance.

The Seat Stainless Steel 90428 is fully compatible with KUNDA, KMT, FLOW, and OMAX waterjet systems and can be used in both OEM and aftermarket applications. It works seamlessly with high-pressure outlet assemblies, check valves, and intensifier heads, forming part of the core structure that maintains reliable system performance and cutting precision.

Ideal for industries such as metal fabrication, stone processing, ceramic machining, and composite cutting, the 90428 stainless steel seat provides the durability and sealing accuracy required for long-term, high-pressure operation.
