Butterfly Valve Lockout - 3 11/32” Valve Head Diameter

TRADESAFE butterfly valve lockout helps maintenance teams, safety personnel, contractors, and authorized employees secure compatible butterfly valve handles during servicing, repair, inspection, and other lockout activities. Designed for valves with a 3 11/32" head diameter and handles up to 14-3/4" long, 1-1/2" wide, and 1" thick, the device provides a practical way to restrict handle movement on appropriately sized stainless steel, PVC, tri-clamp, and other compatible valves.

Made from impact-resistant polypropylene, this red valve lock combines a durable industrial construction with a simple two-piece design for straightforward installation. The main body covers the valve head while the adjustable outer sleeve blocks the handle release trigger, and three integrated lockout points allow up to three authorized employees to attach individual LOTO padlocks during maintenance or servicing activities.

Butterfly Valve Lockout for Compatible Valve Handles

This butterfly valve lockout is designed to fit compatible lever-operated valves while restricting access to the handle release mechanism. Its adjustable two-piece configuration allows the device to be positioned over the valve head and secured around the handle without requiring additional installation tools.

The combination of defined valve dimensions and an adjustable sleeve makes this configuration particularly useful for facilities that need a dedicated lockout solution for compatible butterfly valve handles rather than a universal device intended for several unrelated valve styles.

Butterfly Valve Lockout Device with Three Lock Points

This butterfly valve lockout device combines durable polypropylene construction with a multi-lock design that supports both individual and group lockout applications. Once positioned over the valve head, the adjustable sleeve slides into place to block the handle release trigger, helping keep the lever from being returned to its operating position while the device remains secured.

Design and lockout features include:

• Industrial-strength polypropylene body
  • Lightweight for routine transport and storage
  • Resistant to impact during regular workplace handling
• Two-piece sliding construction
  • Allows fast positioning over compatible valve handles
  • Does not require additional installation tools
• Three lockout points
  • Allow up to 3 authorized employees to attach personal LOTO padlocks
  • Support single-worker or multi-worker applications
• Lock holes sized for shackles up to 5/16"
• High-visibility red body
  • Makes the lockout point easier to recognize
• Integrated warning label
  • Provides an immediate visual indication that the valve is locked out
• Adjustable sleeve design
  • Blocks access to the valve handle release trigger

The three-lock configuration is especially practical for servicing activities involving multiple authorized workers. Each employee can attach a personal padlock to the same valve lockout, making this device suitable for maintenance teams, utility operations, process facilities, production environments, and other workplaces where several employees may be involved in the same valve isolation task.

Butterfly Valve Lockout Tagout for Maintenance and Servicing

Butterfly valve lockout tagout is commonly used where lever-operated valves control the movement of liquids, gases, or other process media and must remain in a restricted position during servicing. This device is suitable for compatible stainless steel, PVC, and tri-clamp butterfly valves used in industrial processing, utilities, maintenance systems, water-handling applications, production areas, and other facilities with appropriately sized valve handles. Its dedicated geometry helps keep the lockout focused on the valve head and release mechanism rather than relying on an improvised method of restricting handle movement.

The two-piece construction also makes the device practical for recurring lockout work. Authorized personnel can position the body over the valve head, slide the outer section into place to block the trigger, and secure the assembly with the required personal LOTO padlock or padlocks. With capacity for up to three locks, the same butterfly valve lockout can support an individual technician or a small group working on the same isolated valve without requiring a separate multi-lock accessory.

Add the TRADESAFE butterfly valve lockout to your valve isolation equipment for a durable and clearly visible way to secure compatible butterfly valve handles. Use its adjustable two-piece design and three padlock positions to support routine maintenance, servicing, and multi-worker lockout applications. Choose the configuration sized for a 3 11/32" valve head when your valve and handle dimensions fall within the stated compatibility limits.
