Sanitary Stainless Steel Flanged Pneumatic Diaphragm Valve

• Regarding diaphragm, combinating EPDM and PTFE, which is secured using SS bolts. The sealing part where contact with the medium is of PTFE material, it has good cold resistance -13℉ (-25℃), excellent heat-resistance 482℉ (+250℃), tolerance to most chemicals, and excellent abrasion resistance to medium flow.
• The general state is closed, the elbow diaphragm is close to the inner cavity of the valve, closing the path of the pipeline.
• Toggle the handwheel or drive the actuator to drive the valve stem upward, and the spherical diaphragm bends upward, so that the valve is in a conductive state, and the purpose of cleaning and opening can be achieved. The diaphragm separates the inner cavity of the lower valve body from the inner the cavity of the upper valve cover; so that the valve stem, valve core and other parts located at the upper part of the diaphragm are not corroded by the medium, the packing sealing structure is omitted, and no medium leakage occurs. The optimized valve body design allows the cleaning fluid to be drained completely without stagnation.
