Torque Specification 2 Pdf Gear Valve Torque specification 2 free download as word doc (.doc .docx), pdf file (.pdf), text file (.txt) or read online for free. Before the actuator can be sized for any given valve application, the amount of torque required by the valve must be determined.

Torque Tooling Specification Download Free Pdf Equipment Double acting (air to air): determine the air supply pressure available to the actuator and select the actuator size that exceeds the total valve torque requirement. 3.1 calculated final valve torque (fbto) based on temperature and seat material: 3.1.1 torque values for valves with extended length up to 1 meter stem for underground application or insulation purpose, increase torque values by 1.1 times. 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. Torques shown are with graphite stem packing (bolted bonnet design), ptfe packing will be lower torque. *dl = double sided. **thread size & pitch can vary. = medium working pressure cwp = cold max.

General information: this bulletin contains basic information on determining the actual valve torques to be used for actuator selection. the following pages contain valve torque graphs and tables for the various sharpe® valve models, along with media and service factors which must be considered. For cryogenic ball valve, torque will be 2~2.5 times the above torque. torque shown in this table is to be used as a guide for actuator selection. a safety factor of 1.5 is recommended for actuator sizing. torque may be changed according to different medium and trim material. The following chart details required torque to operate vic ball series 726s ball valves under varied working pressure conditions. this chart may be used to determine optional gear operator or remote electric or pneumatic actuator requirement. Due to the different design demands, depending on the relevant standard, the characteristics of the valves are different with respect to strength, closing torque, number of turns etc.
