Product Overview
The Gate Valve Lock (M-H06B / M-H07B) is an engineered lockout/tagout device designed to secure gate valve handwheels with diameters ranging from 450 mm to 600 mm, preventing unauthorized or accidental valve operation during maintenance and servicing activities. Constructed from high-grade engineering plastic ABS, the lightweight thermoplastic housing delivers outstanding resistance to chemicals and harsh environmental conditions. Its compact semi-circular split design allows two units to nest together for storage, cutting the combined footprint by half and making transport and inventory management effortless.
Key Features
- Fits gate valve handwheels with diameters from 450 mm to 600 mm
- Made from durable engineering-grade ABS thermoplastic – lightweight yet robust
- Chemical-resistant and effective in extreme operating environments
- Semi-circular split design (M-H06B / M-H07B) combines and nests for compact storage, reducing volume by 50%
- Accepts up to 2 safety padlocks with lock-beam diameter ≤ 7 mm for multi-lock group isolation
- Includes high-visibility permanent security labels printed in English
- Standard colour: red; custom colours available on request
- Optional transparent PC version available – high temperature and impact resistant
- Insulated housing adds an extra layer of electrical safety
- Prevents accidental or unauthorised opening of gate valves during LOTO procedures

Product Benefits
By enclosing the gate valve handwheel and accepting two independent safety padlocks, this lock physically blocks any attempt to open a valve while maintenance is in progress, dramatically reducing the risk of hazardous energy release and protecting every worker on site.
The ABS thermoplastic housing resists a wide spectrum of industrial chemicals and maintains its structural integrity across extreme temperature ranges and harsh site conditions, ensuring the device performs when it is needed most.
The unique semi-circular split profile of the M-H06B / M-H07B allows both halves to lock together when not in use, cutting storage volume by 50%. This makes bulk storage, tool-crib management, and on-site transport significantly more practical for safety teams.
The bold red colour and high-visibility permanent security labels communicate lockout status at a glance, supporting a safety culture of clear communication and reducing the likelihood of procedural errors during complex multi-trade shutdowns.
Available in custom colours to match site-specific colour-coding systems, and in a transparent PC version for facilities that require direct visual confirmation of valve position, the product adapts to a wide range of industrial safety programmes.
