ZMAQ pneumatic diaphragm shut-off valve

ZMAQ pneumatic diaphragm shut-off valve adopts top guide structure and is equipped with multi spring actuating mechanism. It has the advantages of compact structure, light weight, sensitive action, fluid channel S streamline, small pressure drop loss, large valve capacity, easy disassembly and assembly, etc.. The cut-off valve receives the signal from the regulator, cuts off, opens or changes the flow direction of the medium, and achieves the automatic control of the process parameters such as pressure, flow rate and liquid level. Widely used in petroleum, chemical, metallurgy, electric power, light industry, textile and other industrial production process automatic control and remote control system.

Structure characteristics
1. The cutting valve adopts a multi spring actuating mechanism and the adjusting mechanism is connected by three roots, the whole height can be reduced by about 30%, and the weight can be reduced by about 30%.
2. The valve body is designed as a uniform flow channel with low flow resistance according to the principle of fluid mechanics, and the number of rated flow system increases by 30%.
3, the sealing part of the valve has two types of tight and soft sealing, the strict type is hardfacing hard alloy, soft sealing type is made of quality material, closed into the sealing performance is good.
4, balance valve internals, improve the allowable pressure difference of the cut-off valve.
5, bellows seal type of moving stem to form a complete seal, blocking the possibility of leakage of media.
6, piston type actuator, operating force, the use of pressure difference.
