NOSHOK Valves Receive Patent For Innovative New Valve Design

NOSHOK has been awarded a patent for an innovative new valve design, which features a unique body-to-bonnet metal-to-metal seal that significantly increases the pressure range of the valve without compromising the flow. This design also helps to maintain the integrity of the bonnet threads by segregating them from the process media. (Patent No. US 7,758,014 B2)

The body seal incorporates a dovetail undercut below the seal that improves the metal-to-metal contact forces as pressures increase, as well as a dual outlet orifice to maximize fluid flow. These novel design features increase the pressure limits of the valve to 10,000 psi, which is significantly higher than similar-sized miniature needle valves.
