Product Overview
The Gate Valve Lock is a purpose-engineered lockout/tagout (LOTO) device designed to secure gate valve handwheels with diameters ranging from 330 mm to 450 mm, effectively preventing unauthorized or accidental valve operation. Constructed from high-strength ABS engineering plastic, the device delivers exceptional chemical resistance and reliable performance under extreme environmental conditions. Its compact semi-circular two-piece design (models M-H06B and M-H07B) nests together for space-efficient storage and effortless deployment on the job site.

Product Benefits
By physically blocking handwheel rotation, the Gate Valve Lock eliminates the risk of accidental valve opening during maintenance, protecting workers from sudden releases of hazardous fluids, pressure, or gases.
The ABS engineering plastic housing resists a wide spectrum of industrial chemicals, oils, and solvents, and continues to perform dependably in extreme temperatures and demanding outdoor environments common across Saudi Arabia's industrial sectors.
The innovative semi-circular two-piece design allows both halves to snap together into a single compact unit, cutting storage volume by half. This makes bulk storage, toolbox organisation, and on-site transport straightforward and clutter-free.
With two hasp holes accommodating padlocks of up to 7 mm beam diameter, the device supports multi-authority lockout scenarios where multiple tradespeople or supervisors must each apply their own padlock before energy isolation is confirmed.
The bold red colour and permanently affixed English-language warning labels ensure the lockout status is immediately visible to all personnel in the work area, reinforcing a culture of safety and reducing the risk of oversight.
