Heavy-duty fork-type pneumatic actuator

　　In order to meet the torque output requirements of high torque valves, conventional rack and pinion actuators often do not meet the technical requirements and cost-effectiveness. In the selection of pneumatic actuators, it is generally recommended to choose a high-power fork-type pneumatic actuator, which can provide higher torque output and larger diameter valve control.

　　The main technical parameters

　　Power air source: dry or lubricated air, non-corrosive gas, oil, impurity particles in the medium <30μm;

　　Air source pressure: minimum air source pressure 3Bar, maximum air source pressure 10Bar;

　　Working temperature: standard type: -20 ℃ ～ + 80 ℃; low temperature type -40 ℃ ～ + 80 ℃; high temperature type -20 ℃ ～ + 150 ℃;

　　Connection standard: the air source interface, the output shaft and the installation size of the top of the cylinder comply with the NAMUR standard;

　　The installation dimensions of the bottom of the cylinder comply with S05211, DIN3337 standards;

　　Stroke adjustment: two independent stroke adjustment screws can adjust the opening and closing positions conveniently and accurately ± 6 °;

　　Cylinder body material: carbon steel covered plastic, stainless steel;

　　Optional valves: ball valve, butterfly valve, plug valve and other angular stroke valves.

　　Maximum torque output: single-acting can provide more than 110000Nm, double-acting can provide more than 240,000Nm of torque output.
