Noshok 2-valve block and bleed needle valves

Noshok’s 2-valve block and bleed needle valves offer a 10,000 psi pressure rating (at 93°C maximum), and are 100% helium leak tested to 1 x 10-4 mL/s.

The 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.

Other features include a ¼ NPT vent plug located 90° to the left that may be removed and replaced with exhaust piping to direct the fluids to a safe location and a ½ NPT connection, with M-F and F-F configurations available and optional right venting. A blowout-proof stem provides a secondary stem seal in the full open position and all stems are made from 316 stainless steel.

The unit is 10 cm standard length and a 13.6 cm extended length is available as well as optional panel-mount bonnet and panel nuts. They are also available in a soft-seat version.
