Universal valve lock (one-arm ball valve lock) — durable, simple locking for standard valves Key benefits Prevents accidental or unauthorized valve operation by mechanically locking the valve handle in place. Universal design fits all types of standard valves, making it a practical single solution for multiple valve styles. Robust construction reduces downtime and maintenance needs by protecting large levers and mechanical controls from unintended movement. How it works The one-arm clamp locks onto the clamp connected to a ball valve or a wing-shaped (flange) handle, preventing the handle or trigger from being actuated. Simple installation: position the clamp over the handle connection and engage the lock to immobilize the lever. Materials and performance Made from high-quality nylon and stainless steel for long service life. Properties include high crack resistance, excellent wear resistance, effective dust resistance, and good elasticity for reliable clamping and repeated use. Designed to withstand industrial conditions where valve handles and levers are exposed to frequent use and stress. Compatible uses and applications Universal model suitable for standard valves, including industrial ball valves and other common valve types. Effective for locking large levers, handles, wheel-type valve handles, and mechanical devices that are difficult to service or repair. Practical scenarios Plant maintenance: Lock out valves during maintenance or service to prevent accidental flow restoration and improve worker safety. Process isolation: Secure critical ball valves in chemical or manufacturing lines while performing equipment changes or inspections. Equipment protection: Prevent unintended operation of large handles or wheel valves in industrial settings, reducing the risk of damage or costly downtime. What it secures Large levers and handles Wing-shaped/winged handles Wheel-type valve handles Mechanical devices with valve-like handles that require stable immobilization Simple, durable, and universally compatible — a straightforward locking solution for standard valve safety and protection.
