SPUV-M-4N : Superlok Purge Valve, 1/4 MNPT, Purge Valve

The Superlok SPUV series purge valves are manual bleed, vent, or drain valves. One-quarter turn with a wrench from finger-tight obtains leaktight closure on the first makeup. Snugging with a wrench ensures closure to the rated pressure with subsequent makeups. When installing a Superlok purge valve, position the vent hole to direct system fluid away from operating personnel. The vent hole rotates with the cap, changing the direction of discharge as the cap is turned. Always open purge valves slowly. These valves contain no packing, so some fluid seepage will occur when the valves are opened. Operating personnel must protect themselves from exposure to system fluids.
