NOSHOKâs patented 800/850 Series bleed valves provide a convenient means to relieve process pressures trapped between a shut off valve and the instrument, with pressure ratings up to 10,000 psi.
NOSHOK 800/850 bleed valves use the same patented features as the NOSHOK 100/150 Series mini valves, with an integrated single threaded body for insertion in a vent port. These valves provide shutoff to a small bleed hole located on the side of the hex which vents the process media to the atmosphere.
Soft tip valves feature a patented DelrinÂ non-rotating soft tip stem, and a back-up metal-to-metal seal, designed to significantly increase the pressure range of the valve.
NOSHOK bleed valves are available in zinc-nickel plated steel, electropolished stainless steel and brass. All NOSHOK bleed valves are equipped with an FKM o-ring and PTFE back up ring below the stem threads to protect against corrosion and galling. PTFE or GrafoilÂ® packing is optional. The stem threads are rolled for greater strength and ease of operation, and they have a maximum pressure rating of 10,000 psi for steel and stainless models, and 6,000 psi for brass models.
All NOSHOK valves are 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability.
