NOSHOK's patented needle and manifold valves provide an innovative design, featuring a unique body-to-bonnet, metal-to-metal seal that significantly increases the pressure range of the valve without compromising the flow coefficient. The design also assists in maintaining the integrity of the bonnet threads by segregating them from the process media.
Built for maximum durability and performance in the toughest applications, NOSHOK valves are available with Zinc-Nickel plating, which provides one of the highest levels of corrosion resistance available. Additionally, all NOSHOK valves are 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability.
Valve models incorporating this patented design include the 100 Series hard seat mini valves, 800/850 Series bleed valves, all 2-valve block and bleed valves along with 5-valve manifolds.
