DI diaphragm valve
1. Diaphragm made of rubber and other soft seals has the good sealing performance. Since the diaphragm is a vulnerable part, it should be replaced regularly according to the characteristics of the medium.
2. Due to the limitation of diaphragm material, diaphragm valve is suitable for low pressure and relatively low-temperature occasions.
3. Diaphragm valves can be divided into six types according to their structure: house type, DC type, cut-off type, straight-through type, gate type and right-angle type; the connection form is usually flanged connection; according to the driving mode, it can be divided into manual, electric and pneumatic There are three types, of which pneumatic drive is divided into three types: normally open, normally closed and reciprocating.
