Double block and bleed valve from NOSHOK

By hcentorbi | August 8, 2012

Share

NOSHOK valveThe 3070 Series Double Block & Bleed Valve from NOSHOK has redundant isolation valves and a dedicated vent valve for additional safety in hazardous media applications.

NOSHOK 3070 Series Double Block & Bleed Valves have a 10,000 psi hard seat pressure rating @ 200 °F. The block valve isolates the downstream process fluids, while the bleed valve exhausts upstream fluids letting instruments be removed without disturbing the permanent piping installation on the bottom.

The 1/4″ NPT vent plug is located 90° to the left and may be removed and replaced with exhaust piping to direct the fluids or gases to a safe location.

-All NOSHOK valves are 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability
-Blow-out proof stem gives a secondary stem seal in the full open position
-FKM o-ring seal and PTFE back-up ring below the stem threads to protect from corrosion and galling; PTFE
or Grafoil® packing optional
-All stems are 316 stainless steel
-One-piece bonnet with a metal-to-metal seal to the valve body below the bonnet threads
-Slotted spring pin to prevent accidental bonnet loosening
-Vinyl dust cap for bonnet and stem (non-packing)
