Self-locking self-locking device can be added to achieve the control valve and secure his position

The fine small pneumatic diaphragm actuators institutions made an important improvement, which uses a plurality of springs instead of the original one spring, reducing the height and weight of the implementing agencies, the advantages of compact, energy-saving, output thrust. Height and weight can be reduced to approximately 30% compared with conventional pneumatic diaphragm actuator. Four spring structure fine small pneumatic diaphragm actuator diagram.
Side-mounted pneumatic diaphragm actuators, also known by force actuator, also known abroad ΣF series actuators. It uses the energizing means the horizontal thrust of the pneumatic diaphragm actuators by the zoom lever, converted to thrust in the vertical direction. As in the energizing means can be easily replaced parts to replace the connection between the positive and negative mode of action, to change the magnification, magnification of the energizing means, for example, up to 5.2, the domestic product is also up to 3, and therefore, by users.pneumatic hand valve
Rolling diaphragm actuators are rolling diaphragm, the amount of displacement in the same effective area, than with the piston actuator, less friction, and good sealing characteristics. It is usually supporting the use of eccentric rotary valve.direct acting solenoid valve
