NSCNeedle valves provide reliable pressure seal for a range of applications using a variety of stem designs, sealing patterns, materials, and end connections in designs such as integral-bonnet and union-bonnet. Needle valves provide the ability to make fine pressure shut off to accurately control system flow in low- and high-pressure application at desired temperature.
Needle Valves are use in general-purpose applications to isolate or vent system media. The hardened stainless steel and integral bonnet design, nonrotating needle promotes leak-tight shutoff and long service life. The valve stem threads are isolated from the media. Compact design. Stainless steel stop pin. High-temperature packing and bonnet seal option available. Anti-tamper and lockable handle features available. Available in straight as well as angular pattern.
