Detailed Product Description


Air operated sleeve regulating valve

Product outline

 The ZXM new series air operated thin film sleeve regulating valve is - the pressure balance-like regulating valve. Uses for parts the multi-spring implementing agency, the gross structure is compact, the weight is light, the stability is good. The fluid channel assumes the S streamline form, the pressure drop loss to be small, the permission differential pressure is big, the noise is small, the flow capacity is big. Widely applies in medium technological parameter like pressures, the current capacity, the temperature, the fluid position and so on accuracy control gas, liquid maintains at the given value. Is suitable specially in the current capacity is big, the differential pressure is big, spillage request not high situation.
    This serial products has the standard type and the adjustment cut-off, the corrugated pipe seal, the clamp cover heat preservation and so on many kinds of varieties. The product nominal pressure rank has PN10, 16, 40, 64, the valve chest caliber scope by DN20~200, is suitable the fluid temperature by - 200 to +560, in its scope many kinds of scales. The spillage standard has IV level or VI level. The discharge characteristic is the linearity or and so on percentages. Many kinds of varieties, the specification may supply the choice.

  Product characteristic

· uses the balanced -like valve core structure, the axial balance force is not small, the permission differential pressure is big, the stability is good.
· sleeve interchangeable, disassembling is convenient, easy to service.
· the pure metal valve core structure is suitable many kinds of work situations, achieves IV level of divulging standard, the ZXMQ soft seal structure valve core achieves VI level of divulging standard.
· the valve chest designs the constant section low resistance to flow flow channel according to the hydromechanics principle, the adjustable range is big, inherent adjustable compared to is 50, the rated flow coefficient increases 30%.
· the implementing agency uses the multi-spring structure, reduces 30% highly. Weight saving 30%.
· The ZXMV corrugated pipe seal regulating valve, has formed the complete seal to the motion valve lever, stops up outside the fluid to leak certainly.
· The ZXMJ regulating valve has the heat preservation clamp cover, after using in the fluid cools, crystallizing, the coagulation easily to create the jamming the situation.
