The NOSHOK 100 and 150 Series mini valves available from AMS Instrumentation and Calibration are compact-sized valves designed with high performance capabilities and durability.  

Suitable for extremely tough applications, the mini valves are available in zinc nickel plated steel, electro-polished stainless steel and 360 brass construction options.  

Corrosion and galling are prevented with a Viton O-Ring seal and a Teflon back-up ring below the stem threads. The stem threads are rolled for strength and ease of operation.  

Their patented design incorporates an improved internal body-to-bonnet, metal-to-metal seal. The body seal has an innovative dovetail feature that improves the metal-to-metal contact forces as pressures increase on the mini valves.  

Key features of NOSHOK 100 Series hard seat mini valves: 

  • Maximum hard seat pressure rating of 10,000 psi for the stainless steel and steel models
  • 6,000 psi rating for the brass models
  • 316 stainless steel stem
  • Stem tip on the stainless steel valve is hard chrome-plated to prevent galling

Key features of NOSHOK 150 Series soft tip mini valves: 

  • Patented non-rotating soft tip stem
  • Soft tip-to-metal seal helps extend the service life of the valve by easily conforming to the metal sealing surfaces
  • Pressure rating of 6,000 psi for stainless steel and steel models, and 3,000 psi for brass models

NOSHOK mini valves are 100% helium leak tested for guaranteed performance and reliability, and conform to the MSS SP-1999 (R 2005) Instrument Valve Standards.    

Valves supplied with packings conform to MSS SP-132-2004 Compression Packing Systems for Instrument Valves.
