How to select the stainless steel electric pneumatic valve

stainless steel is the realization of program-controlled pneumatic valve, pneumatic valve electric actuator are indispensable to automatic control and remote control equipment, its movement process can be made of the trip or the size of the axial thrust and torque control. Due to the work characteristics of pneumatic valve electric device utilization and depends on the type pneumatic valves, electric butterfly pneumatic valve working rules and pneumatic valve in the pipeline or equipment, therefore, the correct selection of pneumatic valve electric device, to prevent overload phenomenon, Working torque is higher than the control torque is very important.

usually, on the basis of correct selection of pneumatic valve electric actuator are as follows: the operating torque, soft seal butterfly pneumatic valve operating torque is to select the main parameters of the pneumatic valve electric actuator, electric actuator output torque should be maximum torque of pneumatic valve operation. 。 Times. Operating thrust: host structure of the pneumatic valve electric device has two kinds: one kind is not configured thrust plate, direct output torque; The other is a configuration thrust plate, the output torque by thrust plate pneumatic stem nut into output thrust.

output shaft rotation laps: stainless steel pneumatic valve electric device output shaft rotation laps with nominal diameter on the pneumatic valve, pneumatic valve stem thread pitch, thread, according to calculation (M = HZS M for electric devices should satisfy the total number of rotating ring, H is height of pneumatic valve opens, S for pneumatic valve stem drive screw pitch, Z for pneumatic valve stem thread wafer hard seal butterfly valve pneumatic valve.
