Application
Control valves for control equipment subject to special safety
Requirements applicable to gas supply.
For gaseous fuels acc. To EU Directive 90/396/EEC
DN 15 to 150 · PN 40 · 20 to 220 ° C.
The process medium flows through the strainer and the valve in
The direction indicated by the arrow. The plug stem is sealed by
The metal bellows and a backup safety packing. A test connec -tion enables monitoring of the metal bellows.
The signal pressure p st is applied to the pilot valve (11) whose
Coil is connected to the safety interlock circuit (switch 14, Figs. 3
And 4). During operation, the coil is energized and the signal
Pressure pst acts on the diaphragm. In the event of a malfunc -tion, the pilot valve switches over and the pressure acting on the diaphragm is relieved. The standard valve version then closes quickly.
