It mounts on API or vapor adaptors and locks out the vehicle’s brakes or other pneumatic components until a guarding bar or door is closed, preventing movement during loading or unloading. Built with a strong composite body and a stainless‑steel shaft for electrical continuity, it helps avoid static electricity hazards. The valve is typically replaced when it develops internal air leaks, fails to hold pressure, or otherwise prevents the interlock from engaging properly.
