Product Description

The L1000 Series pneumatic actuator is a multi–spring diaphragm actuator with such features as light weight, small volume, stable output force, etc. Through acting on the diaphragm inside the actuator, the air supply conquers the reverse action force of the spring and makes upward and downward linear movement. When there is no air pressure, the compression spring releases pressure and pushes the push shaft of the actuator to move upwards or downwards. The actuators of this series can be classified into direct action type and reverse action type. According to different diaphragm effective areas and travels, the actuators include the following 5 specifications:

Diaphragm effectivearea (cm²)	Travel	Reverse action	Direct action
360	16	L112B/C	L122B/C
360	25	L113B/C	L123B/C
560	40	L114B/C	L124B/C
900	60	L115B/C	L125B/C
1400	100	L116B/C	L126B/C

The action principle of the L2000 linear motion multi-spring piston pneumatic actuator is the same as that of the multi-spring diaphragm actuator. But the L2000 Series actuator replaces the diaphragm by piston, which has solved the problems of the diaphragm actuator being unable to bear relatively high air pressure and easy ageing of the diaphragm, and the actuator can bear higher air pressure. The increase of the air pressure has enhanced the output force of the actuator. The standard configuration is single acting type. Double acting type actuator can also be designed according to the need.According to different piston diameters and travels,the actuators include the following 4 specifications:

Piston diameter	Travel	Reverse action	Direct action
210	25	L213B/C	L223B/C
270	40	L214B/C	L224B/C
365	60	L215B/C	L225B/C
460	100	L216B/C	L226B/C

Hand operating mechanism

The C0 Series side mounted hand operating mechanism is designed according to the worm gear speed reducing principle. It is featured by exquisite appearance and small operating force. After the air supply is turned off at the site, the user can open or close the valve through rocking the handwheel. Compared with the top mounted handwheel, the side mounted handwheel has lower operating force. Therefore we firstly recommend users to use the side mounted handwheel.
According to different travels, we provide users with three kinds of side mounted hand operating mechanisms.

Model	Travel (mm)	Used for actuator
C2	16/25	L102/L103
C3	40	L104
C4	60	L105

The D0 Series top mounted hand operating mechanism adopts the T model thread inside it to transfer the axial movement. After the air supply is turned off at the site, the user can open or close the valve through rocking the handwheel. Compared with the side mounted handwheel, the top mounted handwheel has lower volume, but higher operating force. For valves with DN > 250, the top mounted hand operating mechanism adopts the bevel gear structure to open or close the valve in case of emergency.
According to different travels, we provide users with five kinds of top mounted hand operating mechanisms.

Model	Travel (mm)	Used for actuator
D2	16	L102
D3	25	L103
D4	40	L104
D5	60	L105
D6	100	L106
