This product is composed of a new pneumatic multi-spring film actuator and a low flow resistance sleeve valve. Features are as follows:
1, the use of balanced core, unbalance force is small, allowed pressure difference is large, stable operation.
2, the spool guide surface is large, can improve the oscillation caused by eddy current and impact, and reduce damage.
3, the noise is reduced by about 10bd than the ordinary single and double seat regulating valve.
4, simple structure, convenient installation and maintenance.
Pneumatic control valve, a compressed air as the power of the control device, through the cylinder actuator and electrical valve positioner, converter, solenoid valve, holding valve and other accessories synergistic effect, to achieve the pipeline medium flow, pressure, temperature and other process parameters accurate regulation. The operating principle is simple and clear, the response is rapid, and the nature is safe, without additional explosion-proof measures. It is composed of a multi-spring pneumatic film actuator and a small regulating valve body with low flow resistance. The multi-spring actuator has low height, light weight and easy equipment. Pneumatic low temperature control valve body flow channel is streamlined S, with compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics, easy maintenance and other advantages, can be used in harsh working conditions. Pneumatic low temperature control valve equipped with electro-pneumatic valve positioning or pneumatic valve positioning device can realize the automatic adjustment and control of process pipeline fluid medium. Pneumatic low temperature control valve is widely used in the accurate control of gas, liquid, steam and other media process parameters such as pressure, flow, temperature, liquid level and other parameters to maintain the given value of gas
