Products Details

ZXM pneumatic sleeve control valve

It is widely used to accurately control the process parameters of gas, fluid, steam and other media, such as pressure, flow, temperature, liquid level to keep at the given value. It is especially suitable for the occasions with large allowable flow, large pressure difference and low leakage requirement.
This series of products have many varieties, such as adjusting type, adjusting cut-off type, bellows sealing type, jacket insulation type, etc. The nominal pressure rating of the products are PN10, 16, 40 and 64; The diameter range of valve body is DN20 ~ 200. It is suitable for fluid temperature from - 200 ℃ to + 560 ℃. There are IV or VI leakage standards. The flow characteristics are linear or equal percentage. A variety of varieties and specifications are available.


Product features:
1.Adopt balanced valve core structure, small axial balance force, allowable pressure difference and good stability.
2.Strong interchangeability of sleeve, easy disassembly and repair.
3.The all metal valve core structure is suitable for various working situations, reaching the IV level leakage standard, ZXMO type soft seal structure valve core reaching the VI level leakage standard, ZXMP type soft seal structure valve core reaching the VI level leakage standard.
4.The valve body is designed as a constant cross-section low flow channel according to the principle of fluid mechanics, with a large adjustable range, an inherent adjustable ratio of 50, and a 30% increase in the rated flow coefficient.
5.The actuator adopts multi spring structure, which reduces the height by 30% and weight by 30%.
6.ZXPV bellows seal type control valve forms a complete seal to the moving valve stem, blocking fluid leakage.
7.ZXPJ type control valve is equipped with heat preservation jacket, which is used in the occasions where the fluid is easy to crystallize and solidify after cooling.
