Check Valve Seat 300640 Glass WaterJet Cutter Parts

The Check Valve Seat 300640 is a critical precision sealing component used in ultra-high-pressure Waterjet Intensifier Pumps and valve assemblies. It provides the sealing surface against which the check valve ball closes, ensuring one-directional water flow, leak-free performance, and consistent system pressure even under continuous 24-hour operation.

Manufactured from hardened stainless steel or tungsten carbide, the 300640 valve seat delivers exceptional wear resistance, corrosion protection, and dimensional accuracy, essential for long-term reliability in environments operating up to 60,000 psi (4,100 bar). Its polished sealing surface ensures a tight metal-to-metal seal with the check ball, minimizing pressure loss and preventing backflow.

The Check Valve Seat 300640 is fully compatible with leading waterjet brands including KMT, FLOW, OMAX, WSI, and BFT, making it an ideal OEM-equivalent replacement part for high-pressure pump maintenance and rebuilds.
