On/Off Valve Needle Integrated 42017 Good Quality Waterjet Parts

The On/Off Valve Needle Integrated 42017 is a precision-engineered high-pressure needle assembly designed to regulate and control the start and stop of water flow in Waterjet Cutting Systems. Serving as the central control element within the on/off valve body, this integrated needle ensures instant response, tight sealing, and long-term reliability under extreme operating pressures.

Manufactured from ultra-hard stainless steel or tungsten carbide-tipped materials, the 42017 valve needle delivers exceptional wear resistance, corrosion protection, and dimensional accuracy. Its integrated one-piece design eliminates alignment issues common in multi-part needles, resulting in improved flow control, faster valve actuation, and reduced maintenance frequency. The needle’s finely ground tip and mirror-finished sealing surface guarantee precise shutoff, preventing leaks and maintaining stable system pressure up to 60,000 psi (4000 bar).

The On/Off Valve Needle Integrated 42017 is fully compatible with leading waterjet systems such as KUNDA, KMT, FLOW, and OMAX, making it a reliable OEM-quality replacement part. It is commonly used in cutting head on/off valves, intensifier outlet controls, and remote cutting stations where accuracy and durability are critical.

This needle assembly is essential for high-precision waterjet cutting operations across metal fabrication, stone processing, glass manufacturing, ceramic machining, and composite cutting, offering superior performance and long operational life.
