Product Benefits
With a handwheel diameter range of 25 mm to 635 mm, this gate valve lock is suitable for an exceptionally wide variety of valve sizes, reducing the need to stock multiple lockout devices and simplifying your LOTO inventory management.
The ABS engineering plastic housing is resistant to a broad spectrum of industrial chemicals and maintains structural integrity under extreme temperature and environmental conditions, ensuring long service life on the plant floor or in the field.
By physically enclosing the valve handwheel and accommodating a safety padlock (beam diameter ≤ 7 mm), the device provides a clear, tactile barrier against accidental or unauthorised valve operation, directly supporting your facility's LOTO compliance and worker protection objectives.
The standard red colour and included high-visibility permanent security labels communicate danger at a glance, helping maintenance teams and operators instantly identify locked-out equipment and reducing the risk of human error.
Available in custom colours and with an optional transparent PC version offering superior impact and heat resistance, the gate valve lock can be tailored to meet site-specific colour-coding requirements or application conditions.
