Noshok 3070 Series double block and bleed valve

Noshok has announced the 3070 Series double block and bleed valve with redundant isolation valves and a dedicated vent valve to ensure additional safety in hazardous media applications.

The Noshok 3070 Series has a 700 bar hard seat pressure rating at 95°C. The block valve isolates the downstream process fluids, while the bleed valve exhausts upstream fluids, enabling instruments to 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 and a blow-out proof stem provides a secondary stem seal in the full open position.

An FKM O-ring seal and a PTFE backup ring below the stem threads protect from corrosion and galling, while a PTFE or Grafoil packing is optional. All stems are made from 316 stainless steel and all stem threads are rolled for strength and ease of operation.

There is a one-piece bonnet with a metal-to-metal seal to the valve body below the bonnet threads and a slotted spring pin prevents accidental bonnet loosening.
