ZJHM pneumatic sleeve control valve is a new generation of general control valve products that meet IEC standards. It is widely used in automatic control systems with general fluid media and process conditions in petrochemical, light textile and other industries with compact installation space.
This product consists of a new type of pneumatic multi-spring diaphragm actuator and a low flow resistance sleeve valve. Features are as follows:
1. It adopts a balanced valve core with small unbalanced force, large allowable pressure difference and stable operation.
2. The valve core has a large guide surface, which can improve the vibration caused by vortex and impact and reduce damage.
3. The noise is reduced by about 10dB compared with ordinary single and double seat control valves: 4. The structure is simple and easy to install and disassemble.
