Needle Valve / Bleed Valve

Combines isolating and venting in a single valve, eliminating the need for tubing and fittings. 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. 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 to a safe location. 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability
