Body material - SS316 or 304 Seal - EPDM+PTFE standard.silicone,EPDM optional Suface treatment - ID Ra<0.4μm.OD sand blasted Connection - BPE long type welded,tri clamp end. threaded Operation - Manual,stainless steel actuated,aluminum actuator Application Diaphragm valve is a series of sanitary diaphragm valve which is widely used in wine, dairy beverage, food industry and pharmacy etc. To meet the requirement of control and opening/closing of the pipeline system. Working Principle The diaphragm is closed under the normal state when the diaphragm clings to the cavity of the valve body and closes the flow path through the pipeline. When the diaphragm gets the requirement of cleaning or opening, the valve stem moves upwards according to the manual or pneumatic actuator equipment, spherical diaphragms naturally bend upwards, so that the valve is open and reaches the requirement of cleaning and opening The diaphragm makes the lower body cavity and the upper chamber separated from the valve cover, so that the stem at the top of the diaphragm, disc media and other parts from corrosion, eliminating the need for packing structure, and no media leaks. The optimized valve body makes the cleaning liquid flow out totally so that there will be no retention Materials Steel components: stainless steel 304, 316L Seal: EPDM+ PTFE, the seals are imported seal material (which conform to the FDA1772600 standard). With JACNG unique technology the bolt can connect with EPDM/PTFE to be a perfect whole sealing parts. The PTFE material that gets in touch with the medium has good cold resistance(-25°C)and excellent heat-resistance(+250°C).
