Flat Inlet Poppet WA1028 Water Jet Check Valve Parts

The Flat Inlet Poppet WA1028 is a precision-engineered valve component designed for high-pressure Waterjet Intensifier Pumps, functioning within the inlet check valve assembly to regulate water flow into the intensifier. It ensures one-way flow, preventing backflow and maintaining stable inlet pressure during each reciprocating cycle — even under extreme operating pressures up to 94,000 psi (6,480 bar).

Manufactured from hardened stainless steel or tungsten carbide, the WA1028 flat inlet poppet delivers superior durability, sealing accuracy, and resistance to erosion caused by high-velocity water. Each poppet is CNC-machined and surface-polished to a mirror finish, ensuring perfect alignment and contact with the Inlet Seat WS1037. The flat design provides precise sealing performance and fast response time, reducing wear on the seat and extending the overall lifespan of the check valve assembly.

The Flat Inlet Poppet WA1028 is fully compatible with leading waterjet brands, including KMT, FLOW, OMAX, WSI, BFT, and BHDT, and serves as a direct OEM-quality replacement part. When used alongside the Inlet Flat Poppet Guide WS1040, Inlet Ball Seat WS1037, and Repair Kit WS1039, it helps ensure consistent pressure control, smooth water intake, and high cutting precision.
