The 87K On/Off Valve Spring Disc A-19643-1 is a critical precision component engineered for 87,000 PSI (6,000 bar) Waterjet Cutting Systems. Designed to deliver accurate control, stability, and long service life, this spring disc ensures smooth operation and consistent sealing within on/off valve assemblies—a vital part of every high-pressure waterjet circuit.
Manufactured from premium stainless steel or high-strength spring alloy, the A-19643-1 disc provides exceptional elasticity, corrosion resistance, and fatigue endurance under extreme working pressure. Its precision-ground surface guarantees stable spring performance, maintaining consistent tension and valve responsiveness even after millions of cycles.
Used primarily in waterjet on/off valves, intensifier assemblies, and cutting heads, the KUNDA A-19643-1 Spring Disc helps control fluid flow with high accuracy, ensuring fast, leak-free switching during cutting operations. Each component is produced to exact tolerances to match OEM performance and reliability standards.
