Noshok 2-Valve Block & Bleed Needle Valves
Backed by an exclusive three year warranty, NOSHOK’s 2-Valve Block & Bleed Needle Valves offer a 10,000 psi pressure rating (@200°F maximum), and are 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability.
NOSHOK 2070 Series 2-Valve block and bleed hard seat valves combine isolating and venting in a single valve, eliminating the need for tubing and fittings. The block valve isolates the downstream process fluids, and the bleed valve exhausts upstream fluids enabling instruments to be removed without disturbing the permanent piping installation.

- 1/4” NPT vent plug located 90° to the left, may be removed and replaced with exhaust piping to direct the fluids to a safe location
- 1/2” NPT connection, M-F, F-F configurations available, right venting optional
- Blow-out proof stem provides a secondary stem seal in the full open position
- Viton® O-Ring and Teflon® back-up ring stem seals
- All 316 stainless steel stems (even in steel valves) for extended service life
- Stem and bonnet threads are rolled for strength and ease of operation
- One-piece bonnet with a metal-to-metal seal to the valve body below the bonnet threads
