气动隔膜阀（三联件） Pneumatic diaphragm valve

应用 隔膜阀手动或气动操作，专门应用于制药工业中的卫生和无菌过程。

该阀门非常适用于流体控制和开/关的任务。

工作原理 膜片提供阀体密封和阀座密封。里面没有路径通到外部环境，所以该阀门适用于无菌过程。

当阀门关闭时，支撑膜片的压力垫朝阀体上的密封面移动。当压力板移动时,膜片弯曲，被迫推向阀体中心的阀座区域，因此关闭了通向阀体的流体路径。

阀体和压力板的相互关系，防止了膜片的挤压。

该阀门可以手动也可以气动操作，也可以通过控制器和电磁阀控制。

Pneumatic diaphragm valve

Applications

Diaphragmvalves，manually or pneumatic ally operated，are specifically designed for use on hygienic and aseptic processesin the pharmaceutical industries. The valve is excellent for flow control aswell as for open/close duties.

Operating PrinciplesThe diaphragm provides the body seal as well as the seat seal. There are nopaths to the outside environment and as such the valve is suitable for aseptic processes.

Asthe valve is closed a pressure pad which supports the diaphragm moves towardsthe sealing face on the body. As the pressure plate moves the diaphragm flexes andis forced down onto the seat area in the centre of the body thus closing offthe flow path through the body. The inter-relationship of body to the pressureplate prevents over compression of the diaphragm. The valve can be actuatedeither manually or pneumatically and controlled by control tops and solenoidvalves.

Technical specifications Max.pressure: 10 BAR(145PSl)

Workingtemperature:-10℃ to +120℃(EPDM)- 14°F to 248°F(+ 140℃(SIP,max.30 min) 284°F)

Approvedaccording to Directive PED 97/2 3 EC

Design and featuresThediaphragm valves are better in feature of flow incomparison with other valves. lt is easier to clean up and betterto process the substance with particles. The phenomenon of air pocket is rareduring application of flow control.
