Principle of pneumatic actuators

Pneumatic actuators and electric actuators are used on the valve actuator, we are very common electric ball valve electric valve electric butterfly valve are built into the electric actuator. Pneumatic valve pneumatic ball valve pneumatic butterfly valve? Pneumatic actuators are used, all we can very good part used on valves actuators, hehe! Below we detail powered actuator ( Electric actuator) The working principle.


actuator piston cylinder and crank arm structure, output torque, small volume. Actuator adopt fully sealed waterproof design protection grade is high. Cylinder block USES the import mirror cylinder, oil free, small friction coefficient, corrosion resistance, with super durability and reliability, all drive bearing adopts boundary self-lubricating bearing without oil lubrication, can't ensure that transmission wear and tear.


pneumatic actuators at work, will work the air from A hole input, on both sides of the air pressure in the cylinder to push the piston to move, counterclockwise, the output shaft to drive valve opening and closing operation.
by compressed air hole type B, pushes the piston in the cylinder to center, counterclockwise, the output shaft to drive valve opening and closing operation. This is the working principle of the pneumatic actuator at work I can see actuators can quickly make the rotation of the cylinders. Below we to pneumatic actuators and a detailed introduction, introduced in the following we will from multiple perspectives.



actuators with

1, compact double piston gear rack mechanism, flexible lightweight double piston connecting rod mechanism, Angle of output.


2, material for the die casting aluminum alloy cylinder body ( Aluminum alloy by hard anodic oxidation wear resistance, corrosion resistance, long life) 。


3, gas source: clean air filter, dry or lubrication, small pressure of 0. 1 MPa, pressure 1 MPa.


4, inner surface of special processing to ensure friction and long life.


5, with low friction materials made of sliding device, to avoid the direct contact of metals and metal.


6, bottom fixed hole for actuators connected to the valve and make it to positive, accords with ISO5211 / DIN3337 standard.


pneumatic actuators in compact double piston gear rack mechanism at work, flexible lightweight double piston connecting rod mechanism, Angle of output. The material for the die casting aluminum alloy cylinder body ( Aluminum alloy by hard anodic oxidation wear resistance, corrosion resistance, long life) 。 The inner surface of the pneumatic actuator special handling to ensure that friction and long life.


pneumatic actuators for porosity in accordance with NAMUR standard or in accordance with NAMUR standard adapter plate. Pneumatic actuator stroke adjustment: in 0 ° and 90 ° with a adjustable range of plus or minus 4 °.


all pneumatic actuators actuators are carried on the strict test, to ensure that the product 100% qualified. Pneumatic executing objects bottom hole assembly is square, facilitate connected to the valve stem and can be rotated 45 ° Angle of installation.
