Product introduction:
ZMBQ pneumatic film cutting valve adopts top guide structure, 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, convenient disassembly and assembly, etc.
The cut-off valve accepts the signal from the regulating instrument, cuts off, opens or changes the flow direction of the medium, and achieves automatic control of the process parameters such as pressure, flow, liquid level and so on.Widely used in petroleum, chemical, metallurgy, electric power, light industry, textile and other industrial sectors of automatic control of production process and process control system.
Product features:
1.The cutting off valve adopts a multi-spring actuator and the adjusting mechanism with three vertical connected, the whole height can be reduced by about 30%, the weight can be reduced by about 30%.
2.The valve body is designed into a low flow resistance flow channel with equal cross section according to the principle of fluid mechanics, and the number of rated flow system increases by 30%.
3.The sealing part of valve inner parts has two kinds of tight type and soft seal, the tight type is hardfacing hard alloy, the soft seal type is made of quality material, and the sealing performance is excellent.
4.Balanced valve trim improves the allowable differential pressure of cut-off valve.
5.The bellows seal form a complete seal to the moving stem, blocking the possibility of media leakage.
6.Piston type actuator, large operating force, large differential pressure.
