NOSHOK BLOCK & BLEED NEEDLE VALVES allow pressure to be bled off without disturbing the permanent piping installation thereby enabling the user to quickly and easily remove and/or replace instruments. The metal-to-metal hard seat design is pressure rated to 10,000 psi @ 200 °F. The all 316 stainless steel blow out proof stem provides greater service life and a secondary stem seal in the full open position. Stem seals, with the FKM o-ring and PTFE back up ring, are below the threads and protect against galling and corrosion. The 600 Series Valves are 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability.
