Noshok 100 and 150 Series mini valves

Click2Contact

Noshok 100 and 150 Series mini valves are small in size and are available in zinc nickel-plated steel, electropolished stainless steel and 360 brass.

These valves are equipped with both a viton O-ring seal and a teflon backup ring below the stem threads to protect them from corrosion and galling. The stem threads are rolled for strength and ease of operation. Their design incorporates an improved internal body-to-bonnet, metal-to-metal seal. The body seal incorporates a dovetail feature that improves the metal-to-metal contact forces as pressures increase.

With a maximum hard seat pressure rating of 10,000 psi for the stainless steel and steel models, and a 6000 psi rating for the brass models, the 100 Series hard seat mini valves feature a 316 stainless steel stem, and the stem tip on the stainless steel mini valve is hard chrome-plated to prevent galling.

The 150 Series soft tip mini valves feature a non-rotating soft tip stem. Unlike metal-to-metal seals, the soft tip-to-metal seal helps extend the service life of the valve by easily conforming to the metal sealing surfaces that may become damaged by corrosion, cavitation or chemical attack. This valve has a pressure rating of 6000 psi for stainless steel and steel, and 3000 psi for brass models.

Noshok mini valves are helium leak tested to 1 x 10^-4 mL/s and conform to the MSS SP-1999 (R 2005) Instrument Valve Standards. Also, valves supplied with packings conform to MSS SP-132-2004 Compression Packing Systems for Instrument Valves.
