7000 Series Sherwood Valve

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.

Flow Control Valves Flow Control

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.

Pressure reducing valves - Spirax Sarco

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.

UNDERSTANDING AND TROUBLESHOOTING VALVES

SYMPTOM - VALVE STAYS ON:* Examine diaphragm for tear or rock dent. Solenoid is rusted. Diaphragm is old. Rub it, if hands turn black, the rubber is going bad. Check for diaphragm bubbling in center; replace if found. Teflon screw on diaphragm is broken off. Hardie 205 Valves built prior to 1997 had a rusting pin. Ultra-High Purity (UHP) High Flow Diaphragm Valve 955 The 955 Series design has no internally wetted threads or springs which minimizes particle generation and particle entrapment for reduced process contamination. The valves exacting design controls seat and diaphragm stresses to provide a reliable and maintenance free service life in taxing applications.
