6 Construction and mode of operation Mode of operation with control devices K16, K17, K18, K19 The pressure to be monitored (operating pressure) is applied on the double diaphragm system and is compared with the setpoint specified by the setpoint springs (response setpoint). If the upper response pressure is reached with control device K16 or K 18 (overpressure) or the lower response pressure is reached with K17 / K19, the amplifier valve opens. Gas flows out of the system to be monitored to the force / pressure converter. The pressure accumulating there slides the piston towards the switching devices and causes a release of the locking device of the valve flap shaft. The springs of the actuator close the SSV. 6 Actuator (K16 for upper setting range) Setpoint adjuster Setpoint spring Vent / Bleed line Restrictor Safety shut-off valve measuring line Double diaphragm system Amplifying valve Control device in released state (K17 for lower setting range) Switch device Pressure piece / resetter Valve cap shaft Switch bearing Guide bushing Controller drum Manual release button Switching rod Pressure / force converter Outlet pressure Atmosphere

7 Construction and mode of operation Mode of operation with control device K10a, K11a The control device is a release mechanism with diaphragm measuring unit and / or piston measuring unit (K10a / K11a), which is held in position by the setpoint springs. The two setpoints (release pressure setpoints) for overpressure and underpressure can be adjusted with the control devices K10a and K11a without influencing each other. If the upper or lower release pressure is reached, the release movement in the control device is transferred over the switching rod to the switching bearing of the switching device. In the process, the locking device of the valve flap shaft is released and the SSV valve flap interrupts the gas flow. Mode of operation with solenoid (electrical release) 7 Closing in case of current failure: With the lifting movement of the magnet, the pressure spring in the magnet is pre-tensioned. If the current circuit is interrupted, the switching rod is moved suddenly towards the switching device by means of the spring pressure and triggers the closing process. Closing with application of current: The lifting movement of the magnet unlocks the release mechanism in the switching device via the switching rod and the SSV closes.
