Pneumatic valve torque calculation method

pneumatic valve torque calculation of concrete is: half the square of the pneumatic valve diameter x. It is concluded that the area of the pneumatic valve plate, multiplied by the bearing pressure ( The pneumatic valve working pressure) Draw a shaft on the static pressure, multiplied by the coefficient of friction ( Check table of general steel friction coefficient. Friction coefficient of rubber, steel. ) , number of times the diameter of axle divided by a quick torque of pneumatic valves, unit for cattle, meters, electric device and pneumatic actuator torque reference TVC take pneumatic valves. Times.
