The 5P diaphragm valve can be used in practical applications as a shut-off fitting, a safety valve and also in the 2/3-way version for distributing or collecting. The key to a long service life and reliability is in the structural design of the diaphragm valve. In comparison to comparison diaphragm valves, the flow is controlled not by the diaphragm alone, but in combination with a 90° sealing cone. The advantage of this is that it saves wear on the diaphragm and prevents particles from accumulating.
