Stem Assembly 302668 Abarasive Waterjet On/Off Valve Parts

The Stem Assembly 302668 is a precision-machined component designed for high-pressure waterjet on/off valves and cutting head assemblies, where it functions as the central actuating element controlling the opening and closing of high-pressure water flow. Built for exceptional strength and accuracy, this assembly ensures consistent valve operation, smooth actuation, and complete sealing during high-pressure cutting cycles.

Manufactured from premium-grade hardened stainless steel, the 302668 stem assembly provides superior wear resistance, corrosion protection, and structural stability under pressures exceeding 60,000 psi (4,137 bar). Every stem is ground and polished to ultra-tight tolerances to ensure precise alignment with internal seals and valve seats — minimizing friction, preventing leaks, and maintaining stable system performance even under demanding, continuous-use conditions.

Fully OEM-compatible with major waterjet brands such as KMT, FLOW, BFT, and WSI, the Stem Assembly 302668 can be installed directly into existing on/off valve assemblies without modification. It’s a trusted replacement part used during valve maintenance or complete overhauls to restore cutting accuracy, system reliability, and long-term performance.
