HVG INDUSTRIAL VALVES 0055: ZJHM Pneumatic Diaphragm Cage Control Valve
Advantage: good stability, large flow, simple maintenance, small size and light weight.
Application: Single seal type – used to clean medium with strict leakage requirement, low pressure difference. It can be used as shut-off valve through upgrading
Double seal type – used to clean medium with low leakage requirement, large pressure difference.
Throttling type – used to be as low noise valve
