概述Outline QZMAT pneumatic diaphragm valve film \ QZMBT diaphragm valve pneumatic membrane pneumatic membrane by the multi-spring diaphragm actuators and components. Diaphragm valve body flow smoothly, cutting components for the elastic diaphragm, valve cover stuffing. Thus the valve control valve flow capacity than the average large and no leakage in the range of allowable pressure shut-off valve can be used. Open air, air to close by the pros and cons of the role of executive agencies to achieve. The valve is suitable for high viscosity fluids, like suspended particles, fiber media and toxic media, corrosive mediators occasions.
1, pneumatic diaphragm valves should be installed vertically in the pipe, the volume and the use of larger weight should be added where the vibration support and clamping.
