Noshok's expanded manifold valve offering includes several three-valve differential pressure manifolds

Noshok's expanded offering of manifold valves includes several three-valve differential pressure manifolds that are backed by Noshok's three-year warranty. 

The manifold valves are designed for use with differential pressure transmitters, incorporating two isolation valves and an equalizing valve in differential pressure measurement. The metal-to-metal hard seat design is pressure rated to 10,000 psi at 200ºF, and the soft Delrin tip design is rated to 6,000 psi at 200ºF. The all 316SS blow out proof stem provides greater service life and a secondary stem seal in the full open position. Stem seal, with the Viton O-ring and Teflon back up ring, is below the threads, and prevents galling and corrosion (teflon or Grafoil packing optional on 3010/3110 and 3610/3710 Series). Stem and bonnet threads are rolled for strength and ease of operation, and manifolds feature a vinyl bonnet and stem dust cap.

All manifold bodies are machined from cold drawn extrusion, allowing Noshok to hold tighter tolerances. All Noshok valves are 100% helium-leak tested to 1 X 10-4 ml/s for guaranteed performance and reliability, and conform to the MSS SP-99-1999(R 2005) Instrument Valve Standards.
