Product details

ZJHM pneumatic sleeve regulating valve is a pressure balanced regulating valve, which adopts sleeve guidance, pressure balanced double sealing surface valve core mechanism, and is equipped with a multi spring pneumatic actuator. The flow channel isSLinear flow, with overall characteristics of work balance, large allowable pressure difference, precise flow characteristics, and low noise. Especially suitable for situations with high flow rates, large pressure differences before and after valves, and no leakage requirements. This series of products comes in various forms such as room temperature type, high temperature type, low temperature type, adjustable cutting type, corrugated pipe sealing type, etc. The nominal pressure rating of the product includesPN1.6、4.0 、6.4、10.0Valve body diameter rangeDN20-300Applicable fluid temperature-196- +560Multiple grades within the temperature range. There are leakage levels of IV, V, and VI. The flow characteristics include straight lines and equal percentage characteristics. Multiple varieties and specifications are available for selection.

1ZJHMOverview of Pneumatic Sleeve Regulating Valve:
The ZJHM pneumatic sleeve regulating valve has a small shape, light weight, high performance, and large capacity, and is a new generation of universal regulating valve products that comply with IEC standards. It is suitable for production process systems with general fluid media and process conditions.
This product consists of a new type of pneumatic multi spring thin film actuator and a low flow resistance sleeve valve. The characteristics are as follows:
1. Adopting a balanced core, with small unbalanced force, allowing for large pressure difference, and stable operation.
2. The large guiding surface of the valve core can improve the oscillation caused by eddy currents and impacts, and reduce damage.
3. Reduce noise by about 10bd compared to ordinary single and double seat regulating valves.
4. The structure is simple and easy to assemble, disassemble, and maintain.
