New generation diaphragm valveIn 2021, Qili has caried out a comprehensive technical upgrade for alldiaphragm valves. The upgraded design is more in line with the high cleantechnology requirements of GMP, ASMEBPE, EHEDG and 3A.
working principle:
working principleManual or pneumatic operation,dedicated to hygienic andasepticprocesses in the phamaceutical industry. The valve is well suited for fluidcontrol and switching tasks, the diaphragm provides body and seat sealing.There is no path inside to the outside environment, so the valve is suitablefor aseptic processes.When the valve is cosed, the pressure padsupporting the diaphragm moves towards the sealing surface on the valvebody. When the pressure plate moves, the diaphragm flexes and is forcedto push ,The seat area towards the center of the valve body, thus closingoff the fluid path to the valve body, the mutual relationship of the valve bodyand the pressure plate, prevents extrusion of the diaphragm.
