Dynatorque BG Multiturn Bevel Gears
Reliable torque and thrust support for multiturn valve operation
Make high-load valves easier to operate, delivering smoother and more controlled torque transmission.
Locking devices
For select Dynatorque valve accessories
Overview
Enhance safety of valve operations
These locking devices provide a practical, field-mountable solution to help secure certain Dynatorque™ valve accessories against unintended handwheel movement. Consequently, they support safer valve operation in maintenance, isolation, and critical service applications.
Compatibility with multiple products simplifies selecting a suitable kit for standard gear operators and manual override configurations. Kits are available in carbon steel as standard, with stainless steel construction an option for applications that require enhanced corrosion resistance.
