aseptic Diaphragm Valve

Applications
WJ6 aseptic Diapragm Valve can be remote controlled by an actuator or manually operated by a handle. It is very applicable to the control of pipe fluid and the switching task. It is widely used in pharmaceutical, dairy, beverage and brewing industries with aseptic working conditions requirements.

Operating Principle
The tight mating of valve body and diaphragms makes the valve body and valve seats sealed, which ensures absolute isolation of internal pipeline and external environment. Therefore the valve is applicable to the aseptic process.

The up and down movement of valve stem causes WJ6 aseptic diaphragm valve to open or close. When valve stem moves upwards, spherical diaphragms naturally bend upwards and separate from valve seat, the valve is open then. When valve stem moves from top to bottom, valve plug makes diaphragms bent and clung to valve seat, the valve is closed then.

WJ6 aseptic diaphragm valve can be operated manually, by pneumatic actuator, or by smart controller.
