Balon Trunnion Actuator Torque Data

Balon Trunnion Ball Valves
Balon offers a rugged four or eight bolt mounting surface for Balon trunnion ball valves. The actuation mounting surface can either be installed at the factory or can be installed while the valve is in service.

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.
(i.e. torque values for pressures that lie between those listed in the chart)
