Transparent PC Donut Lockout with 44mm hole & 35mm inner height (BD-F12T)

BD-F12T Transparent Gate valve lockout

BD-F12T Transparent Gate Valve Lockout Device is a professional lock-on-tag (LOTO) safety device used to lock gate valves in the fully closed position. Made of high-strength PC material, it offers excellent impact resistance and corrosion resistance, enabling it to withstand harsh industrial environments.

Once locked,the gate valve locking device will not jam the valve handwheel, preventing its rotation and locking the valve in the closed position.
handwheel gate valve locking device is made of premium PC material, offering wear resistance, impact resistance, and chemical corrosion resistance.
Suitable for long-term use in harsh industrial environments.
Each gate valve locking device is equipped with a single padlock hole.
The split-shell hinged mechanism allows for quick installation and compact storage when not in use.
The locking device’s unique center-mounted hole design is compatible with lift-stem valves.
These locking devices can be secured using industrial safety hasp lockout and safety padlocks.
Specifically designed to lock out gate valves with handwheel diameters ranging from 64mm to 127mm (2.5” to 5”).

FAQs

1What handwheel sizes does the BD-F12T fit?

The BD-F12T gate valve lockout fits handwheels with diameters from 64-127mm (2.5"-5"), covering standard medium-size industrial gate valves in petrochemical, power generation, and water treatment applications.

2What are the internal dimensions of the BD-F12T?

This circular valve lock features a 44mm center bore and 35mm inner height, engineered for secure fit on medium-size valve handwheels to prevent loosening during LOTO procedures.

3What is the advantage of the transparent PC design?

The transparent PC donut lockout provides ~90% light transmittance for real-time valve position visibility — a dual protection of physical locking and visual warning that opaque valve covers cannot offer. PC material also delivers superior impact and chemical resistance vs. ABS alternatives.

4Is the BD-F12T compliant with international LOTO standards?

Yes, this handwheel lockout meets OSHA 29 CFR 1910.147 and ANSI Z244.1 requirements for lockout device substantiality, ensuring compliance with global EHS audit standards.

5What is the overall size and weight of the BD-F12T?

Dimensions are 185mm × 142mm × 45mm, optimized for medium-size pipeline systems. The compact circular valve lock design integrates valve covers and gate valve lockout functions in one durable PC unit.

6How to install the BD-F12T?

Tool-free installation — the split-type design allows quick placement over the closed handwheel, then secure with an industrial safety padlock (shackle diameter ≤7mm).
