ZJHM Pneumatic Thin Film Sleeve Valve
ZJHM Pneumatic Thin Film Sleeve Valve
Product details
Product Overview
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.
