800/900 Series Bleed Valves

April 9, 2009
NOSHOK 800/900 Series Bleed Valves provide a convenient means to relieve process pressures trapped between a shut off valve and the instrument. The 800/900 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. The Bleed Valve provides shutoff to a small bleed hole located on the side the hex which vents to atmosphere. These Valves are available in electroless nickel plated 12L14 steel, electropolished 316 stainless steel and 360 brass. All bleed valves are equipped with a Viton® O-ring and Teflon® back up ring below the stem threads to protect against corrosion and galling. Teflon® or Grafoil® packing are optional. Their 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 6000 psi for brass models. All NOSHOK valves are 100% Helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability.
