AISI316 pneumatic diaphragm control valve
ZJHM small pneumatic sleeve regulating valve, lightweight, high-performance, high-capacity, a new generation of IEC-compliant universal valve products. It is suitable for the fluid medium and the process conditions in general production process-system.
The product consists of a new type of pneumatic multi-spring diaphragm actuator and low flow resistance sleeve valve.
Features are as follows:
1, using the balance plug, allowing large differential pressure, stable operation.
2, valve guide is large, the oscillation caused by the eddy current and impact can be improved,and reduce damage.
3, compared with ordinary single seat control valve noise reduced about 10bd.
4, simple structure, easy assembly and disassembly and maintenance.
