How to choose ball valve pneumatic actuator?
Ball valve pneumatic actuator drive with all kinds of computer networking, alone or centralized control, Ball valve pneumatic actuator can use the analog or digital variables two kinds of signal control, supporting various kinds of modern control equipment, wild valve production, Ball valve pneumatic actuator is widely used in domestic petroleum, chemical, electric power, metallurgy, textile, food, medicine, environmental protection, urban construction and the research field,and exported to Europe, America, Middle East and southeast Asia market, well received by users.

Ball valve pneumatic actuator  beautiful and exquisite shape, light weight, waterproof sealing structure.F4 guide rings are installed on moving parts of piston, rack and output shaft to achieve low friction, long life and avoid contact between metals.The installation connection size conforms to ISO5211, DIN3337 and VD1 / VDE3845 as well as NUMAR standards to ensure the interchangeability between GTD110 actuators and facilitate the installation of solenoid valves, limit switches and other accessories.

Model selection of ball valve double-acting pneumatic actuator:
Ball valve Double acting actuator is used to determine the torque of the valve first. Under normal service conditions, the recommended safety factor is 15 ~ 20%.The safety value is then added according to the fluid medium used by the valve.Increase the safety value of clean and lubricating media by 20%;Water vapor or non-lubricated liquid medium increases the safety value by 25%;Increase the safe value of 40% to the non-lubricated slurry liquid medium;Non-lubricated dry gas medium increases the safety value by 60%;Non - lubricated particulate medium increases the safety value by 80%.The safety value of non-lubricated particle powder medium transported by gas is increased by 100%;According to the torque value calculated above and the torque table of the double-acting actuator using air source pressure, the accurate GTD model can be obtained.

Model selection of ball valve single-acting pneumatic actuator:
Using the single-acting actuator, according to the torque value calculated above and the use of air source pressure, find the single-acting torque table, first check the spring reset end point, then check the end point of air source working pressure, the air source pressure torque should be greater than the spring reset torque, you can get the exact model.Note: In the GTE single gas-controlled output torque table, the "end" torque of the spring reset is the torque of closing the valve, and the "start" torque of the spring reset is the torque of opening the ball valve.The torque at the beginning of the corresponding air source pressure is the torque in closing the ball valve, and the torque at the end of the air source pressure is the torque in opening the ball valve.
