Sanitary Diaphragm Valve Sealing performance: The diaphragm made of soft seals such as rubber or plastic has good sealing performance. Since the diaphragm is a consumable part, it should be replaced regularly depending on the characteristics of the medium.
Applicable occasions: Due to the limitations of the diaphragm material, the diaphragm valve is suitable for low pressure and relatively low temperature occasions. It is generally not suitable for use in pipelines with temperatures above 60 degrees and for conveying organic solvents and strong oxidizing media, nor in pipelines with higher pressures.
Structural form: According to the structural form, it can be divided into six types: house type, direct current type, cut-off type, straight-through type, gate type and right-angle type. The connection form is usually flange connection, and there are also slip-on flange connection, quick-release flange connection, welding connection, etc.
Driving mode: According to the driving mode, it can be divided into three types: manual, electric and pneumatic. Among them, pneumatic drive is divided into three types: normally open, normally closed and reciprocating. The sanitary diaphragm valve is remotely controlled by the drive device or manually operated by the handle. There are three standards for the drive device: normally closed, normally open and gas-to-gas type.、
