GT valve pneumatic actuator 0 to 90 degree regulation is widely used in ball valves and butterfly valves

  GT pneumatic valve actuator KFF COFI GT series pneumatic actuator is an actuator that converts the input air pressure signal into 90 degrees and then outputs it in the form of torsion rectangle
This series of pneumatic actuator is a small-sized and high-performance actuator structure, which is divided into two types: Double pneumatic control type and single pneumatic control type
Combined with angular stroke control valve, it can be used for adjustment and switching occasions, as well as other rotary motion occasions & Nbsp; KFF COFI GTD double acting pneumatic actuator model selection instructions (for reference): when using the double acting actuator, first determine the torque of the valve
Under normal use conditions, the recommended safety factor is 15 ~ 20%
Then increase the safety value according to the fluid medium used by the valve
Increase 20% safety value for cleaning and lubricating media; 25% safety value shall be increased for water vapor or non lubricating liquid medium; Increase 40% safety value for non lubricating slurry liquid medium; The safety value of non lubricating dry gas medium is increased by 60%; The safety value of non lubricating granular media is increased by 80%
The safety value of granular powder medium transported by non lubricating gas is increased by 100%; The accurate GTD model can be obtained by looking up the torque table of the double acting actuator according to the torque value calculated on the and using the air source pressure& Nbsp; KFF COFI GTE single acting (spring return) pneumatic actuator model selection instructions (for reference): use the single acting actuator, find the single acting torque table according to the above calculated torque value and the use of air supply pressure, first check the end point of spring return, and then check the end point of air supply working pressure
The air supply pressure torque should be greater than the spring return torque, and the accurate GTE model can be obtained
Note: in GTE single pneumatic output torque table, spring return & ldquo; End point & rdquo; The torque is the torque to close the valve, and the spring returns & ldquo; Start & rdquo; The torque is the torque when the valve is opened
The starting torque of the corresponding air source pressure is the torque of closing the valve, and the ending torque of the air source pressure is the torque of opening the valve& Nbsp; Main structural features of KFF COFI GT series valve pneumatic actuator: 1) extruded aluminum alloy cylinder body, after hard oxidation treatment, has hard surface texture and strong wear resistance
2) Compact double piston gear and rack structure, accurate meshing, stable transmission, symmetrical installation position and constant output torque
3) F4 guide rings are installed at the moving parts of the piston, rack and output shaft to achieve low friction, long service life and avoid metal to metal contact
4) , cylinder block, end cover, output shaft, spring, fasteners, etc
are subject to anti-corrosion treatment
5) The spring of single pneumatic actuator is installed after preloading, which can be safely and conveniently disassembled and assembled
6) The pneumatic actuator can adjust the two-way stroke of 0 degree or 90 degree plus or minus 5 degrees in the fully open and fully closed positions
7) The installation and connection dimensions comply with ISO5211, din3337, VD1 / vde3845 and numar standards to ensure the interchangeability between GT pneumatic actuators and facilitate the installation of solenoid valves, limit switches and other accessories
8) The installation and connection holes of the output shaft have a variety of shapes (square hole, shaft key hole and flat hole) for selection
9) the appearance is beautiful and exquisite, the weight is light, and has a waterproof sealing structure
10) There are normal temperature type, high temperature type and low temperature type
