SBLV-M-4N-BH : Superlok Bleed Vent Valve, 1/4" MNPT, Back-Stop Screw, Vent Tube, Bar Handle

The Superlok SBLV bleed valves can be used on instrumentation devices such as multivalve manifolds or gauge valves to vent signal line pressure to atmosphere before removal of an instrument or to assist in calibration of control devices. 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.
