HP Check Valve Seat 500-20-0111 Good Quality WaterJet Cutter Parts

The HP Check Valve Seat 500-20-0111 is a critical precision component designed for high-pressure outlet check valve assemblies in waterjet intensifiers and ultra-high-pressure pumping systems. It provides a perfectly machined sealing surface for the HP Outlet Poppet (500-20-0110), ensuring leak-free sealing, consistent pressure control, and long-term durability in continuous operation environments.

Manufactured from hardened stainless steel or tungsten carbide, the 500-20-0111 check valve seat delivers superior wear resistance, corrosion protection, and impact strength. Each seat undergoes CNC machining, grinding, and lapping processes to achieve a mirror-finish sealing surface, allowing precise contact with the poppet for ultra-tight, repeatable sealing under working pressures up to 60,000 psi (4000 bar).

The HP Check Valve Seat 500-20-0111 is fully compatible with KUNDA, KMT, FLOW, and OMAX waterjet systems, fitting seamlessly into standard Outlet Body (500-20-0100) and HP Outlet Poppet Kit (500-20-0110) configurations. It forms the foundation of the outlet check valve assembly, maintaining system stability and preventing backflow during each high-pressure stroke of the intensifier.

Engineered for extreme reliability and precision, this valve seat is essential for maintaining cutting accuracy, pressure efficiency, and safety in heavy-duty industrial applications such as metal cutting, stone processing, ceramic manufacturing, and composite material machining.
