ZMBQ typePneumatic Membrane Shut-off ValveIt adopts top-guided structure and is equipped with multi-spring actuator. It has the advantages of compact structure, light weight, sensitive action, S streamline fluid channel, small pressure drop loss, large valve capacity, easy disassembly and so on.cut-off valveAccept signals from the regulating instrument, cut off, open or change the direction of media flow, to achieve automatic control of pressure, flow, level and other process parameters. The valve is suitable for ≤ 200 ℃ air, water, steam, oil and other media, is widely used in petroleum, chemical, metallurgy, electric power, light industry, textiles and other industrial sectors of the production process automatic control and remote control system.

Instructions for use

Valve open air pressure of 2 kg (0.2Mpa), the pressure can not be too high, otherwise it is easy to break the diaphragm caused by the valve does not work (can not be controlled to the normal air pressure, please install a gas regulator before the gas inlet). Diaphragm of good and bad just in the diaphragm wear and service life on the manifestation of the kind of mounted on the use of the diaphragm on the broken or the use of the diaphragm soon broken, there is only one possibility is too high to break the diaphragm of the air pressure is too high (air pressure high broken diaphragm and the use of a long time of normal wear and tear of the diaphragm is to be able to see, the bad place is not the same). Keep the pipeline clean do not have impurities, otherwise it is easy to damage the valve spool caused by the valve can not close the leakage, please be sure to pay attention to these two aspects.
