ZJHM series pneumatic diaphragm control valve sleeve is a pressure balanced valve. Equipped with multi spring actuator, compact overall structure, star light, good stability. The fluid channel is the 3 line type, the pressure drop loss, allowing a large pressure difference, low noise, large flow capacity. Widely used for precise control of gases, liquids and other media technology parameters such as: pressure, temperature, flow, liquid level maintained at a given value. Especially applicable to the large flow rate, pressure, leakage requirements is not high.
This series of products are the standard and adjust the cut-off type, bellows seal type, jacket type insulation and other varieties. Product nominal pressure level of a user ~10, 16, 40, 64, valve caliber range by DN20~500, applicable for the fluid temperature from -196 ℃ ~+560 ℃, various grades of its range. The leakage of standard IV, V and VI. Flow characteristics such as linear or percentage. A variety of products, specifications are available.
Characteristic.
1 the balance valve structure, the axial unbalanced force is small, allowing a large pressure difference, stability. Sleeve good interchangeability, convenient assembly and disassembly, easy repair.
2 full metal valve structure is suitable for various occasions, to achieve the IV level leakage standard, soft sealing structure of valve to achieve the VI level leakage standard.
3 valve designed according to principles of fluid mechanics such as low flow resistance load into surface flow, large adjustable range, inherent adjustable ratio 50:1, rated flow coefficient of 30%.
4 implementing agencies for the use of multi spring structure, height reduction of 307%. To reduce the weight of 30%.
5.ZJHMW shaped bellows sealed valve, the stem form of mobile complete sealing, blocking the fluid leakage.
