Balon Floating Ball Valve Actuator Torque Data

Balon Lever Operated Floating Ball Valves
Balon offers a valve actuation package for Balon ball valves 1ʺ bore and larger. Balon’s value added approach to valve automation has made the actuation of Balon ball valves, either currently in service or new valves, simplistic while adhering to the highest levels of quality and accuracy our customers expect. With the exception of the actuator, Balon’s actuation package will include everything required to safely and precisely mount an actuator to a floating Balon ball valve. Balon’s standard off the shelf actuation mounting package offering includes ISO 5211 bolt circles and parallel square drive. Balon can also accommodate

certain actuators using nonstandard bolt patterns or drive options. Please contact the Balon sales department if you have any questions or need further information.

Balon Gear Operated Floating Ball Valves
Balon offers a rugged four bolt mounting surface for all gear operated floating Balon ball valves. The actuation mounting surface can either be installed at the factory or can be installed while the valve is in service.

Actuation Mounting Package

The breakaway torque values listed below do not contain any service or safety factors and are adequate for the operation of Balon ball valves equipped with standard seats and used to control clean liquid or gas at ambient temperature.

The run torque is approximately 50%, or one-half, of the breakaway torque. The re-seat torque is approximately 75%, or three-quarters, of the breakaway torque.

Corrosion, scale, build-up on the ball, or other service conditions can drastically alter torque requirements and should be given consideration when selecting actuation or automation equipment.

Note:
Values are raw torque values for new valves and standard seat materials.
Values contain no service factors.
Customer should determine appropriate service factors.
Use the 285 psi. torque value for pressure differentials of 285 psi. and below.
Intermediate torque values can be determined using linear interpolation.
