BALL VALVE LOCKOUT WITH REAR GEAR

The Prote-GT "L" Type Lockout Device with Auxiliary Backstop is an innovatively designed LOTOTO (Lockout/Tagout/Tryout) accessory that prevents accidental opening or closing of manual quarter-turn ball valves during industrial maintenance and repair operations. Its laterally adjustable width allows it to adapt to various types and sizes of handles, while its auxiliary backstop increases the locking height and length for greater effectiveness. Its engagement points, based on structural mechanics principles, ensure a firm grip without slipping. Available in three sizes for valves from DN 8 to DN 100.
