Shop Superlok Instrumentation SBLV Bleed Valves

The Superlok SBLV Bleed Valve is a valve designed to release pressure from instrumentation devices, like multivalve manifolds or gauge valves, by venting it to the atmosphere. It's commonly used before removing an instrument or during the calibration of control devices. Its compact design allows for easy installation in tight spaces. Additionally, a backstop screw prevents accidental removal of the stem, ensuring safety and reliability. The valve features chrome-plated stem threads and tip to improve its lifespan. It's available with male NPT or ISO Thread end connections for flexibility in installation.


CAUTION: When installing a Superlok bleed valve, position the vent tube to direct system fluid away from operating personnel. Alway open bleed valves slowly. These valves contain no packing, so some fluid weepage will occur when the valves are opened. operating personnel must protect themselves from exposure to system fluids.
