Ball valve torque chart

The torque required to operate a ball valve is a function of friction between the valve's metal parts and its soft sealing materials. The friction points in a floating ball valve are the stem and the ball/seat. Stem torque When tightening the stem nut to compress the stem sealing, the friction between the stem assembly parts is increased. FCD MMASS0008 Ball Valve Actuator Selection Guide 3 A very large percentage of automated ball valves go into on-off service involving clean lubricating media and using TFE, high-temperature or high-pressure sealing materials. For these applications, please refer to the torque charts on pages 4 through 10 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

A typical ball valve torque characteristic is demonstrated in the graph shown on the left. Closing torque is about 80% of the opening or breakaway torque for the softer resilient seats such as TFE, Buna-N, and for 3 and larger valves. Closing torques for harder seats such as Lubetal, High-per Fill, Metal A and Metal G seats, as well as 2 and smaller valves, are nearly identical decompression explosion. Most valve sizes have a provision for the sealant injection to establish a secondary seal.

ACTUATOR SELECTION GUIDE FOR FLOW-TEK BALL VALVES Proper actuator selection is needed to ensure consistent operation of the automated valve. Selecting the proper actuator begins with establishing valve operating torque. Valve operating torque is determined by seating material, operation frequency, media type and line pressure stem seals. MAST (Maximum Allowable Stem Torque) should be considered when using seat materials that require added torque. Frequency of operation is also a factor that should be investigated when selecting a seat material. Pressure vs. Temperature charts for individual valves series shall also be considered when selecting the correct seat material Every day, the professionals who build and maintain our world depend on ASC Engineered Solutions.
