Superior's 7074 Series of 303 SS Diaphragm Packless Valves are designed for a variety of high-purity and high-pressure applications, including analytical & instrumentation gases, EPA protocol gases, environmental monitoring and medical applications using pharmaceutical gases. The 7774 Series of 316L SS Diaphragm Packless Valves are used in corrosive gas applications, Control Valves and Instrumentation - Leslie Controls, Inc.device which delivers an air signal to the diaphragm of the regulator. Figure 3 shows the loading pressures required for various valve sizes and pressure drops. Diaphragm pressure quoted, for any particular size or pressure drop, is the pres-sure required on the diaphragm to open the valve under the existing conditions.
The DAB Series Diaphragm Valves are available in sizes 1/2 in. 6 in., with PVC and CPVC. Possible end connections are true-union socket or threaded and flanged ends. All DAB Series feature a highly visable beacon indicator. Possible diaphragm materials are EPDM, FPM and PTFE. PVDF vapor barrier available upon request for EPDM and PTFE Function Dome-loaded pressure regulatorsThe gas to be regulated is supplied to the dome where it reaches the valve seat. The pilot gas is controlled via a built-in pilot gas regulator and led into the pressure chamber. Here, it acts on a diaphragm whose stroke movement is transferred to the valve seat via a diaphragm plate.

The flow through this seat is directed, in turn, to the main valve diaphragm, where it modulates the main valve. In order to achieve the most stable operating condition, an external pressure sensing line must be used. This allows downstream pressure to feed back to the underside of the pilot Pressure reducing valves Pilot Operated 25 Series Pressure reducing valves CaleffiTHE OPERATING PRINCIPLE of the pressure reducing valve is based on the comparison between two opposing forces. 1) The spring pushes the obturator downwards in the pressure reducing valve opening direction. 2) Forced by the downstream pressure, the diaphragm tends to return the obturator upward in the pressure reducing valve closing direction.
