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 up ward 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:

Thev230d01/v231d01self-operated (after-valve) pressure control valve is composed of the control valve, actuator and a spring used for pressure setting. It is suitable for controlling after-valve pressure in the pipes of non-corrosive liquids, gases and steams. When the after-valve pressure rises, the control valve is closed.
The main features are as follows:
1.It has the pressure balancing function with high sensitivity.
2.Low noise, reliable performance, free of maintenance
3.The standard modular design is adopted.
4.Various combined controls can be carried out through the assemblies.

The 10p series single-seat control valve adopts the top guided unbalanced structure, featured by high strength, heavy load, s type flow channel, low pressure drop loss, high flow coefficient wide adjustable range, high flow characteristic precision, etc. This kind of control valve is suitable for applications with relatively low differential pressure with tight shut-off. It is suitable for controlling medium flow or pressure. The cage adopts the press-in type seat design, which solves the problems of difficult disassembly and high leakage of the traditiona l thread screw-in type seat and prolongs the service life. The flow to open design is adopted, and the medium flow direction tends to the opening direction of the valve with good controllability of small opening and low flow characteristic distortion. Special cages with noise reduction and anti- cavitation functions can be offered according to the requirements in different service conditions.
