Gemi type quick installation diaphragm valve

Stainless Steel Gaimi Type Diaphragm Valve
Features
The diaphragm is made of soft sealing material such as rubber or plastic, which has good sealing performance. Since the diaphragm is a wearing part, it should be replaced regularly depending on the characteristics of the medium.
Due to the limitation of diaphragm material, diaphragm valve is suitable for occasions with low pressure and relatively low temperature.
According to the structural form, diaphragm valves can be divided into six types of connection forms: house-type diaphragm valve, direct-flow diaphragm valve, globe-type diaphragm valve, straight-through diaphragm valve, gate-type diaphragm valve and right-angle diaphragm valve, usually flange The connection can be divided into three types according to the driving mode: manual, electric and pneumatic. The pneumatic drive is divided into three types: normally open, normally closed and reciprocating. The diaphragm valve uses a valve stem to press an elastomer film tightly against the valve seat to isolate the air path. Turning the handwheel can drive the valve stem to move up and down, causing the diaphragm to leave the valve seat to open the valve or to press the diaphragm tightly on the valve seat to close the valve. If this type of valve adopts a nitrile rubber diaphragm, it is suitable for non-corrosive gases on the front stage and pre-extraction pipelines and the temperature is ~℃. If a fluororubber diaphragm is used, it can be used in high vacuum systems, and the operating temperature range is ~℃
