Gas Solenoid Ventil-ZRV20C
2021-03-24
Das Ventil ist eine Serie von Gas-Notfall-Absperrventilen, besonders entwickelt als Gaspipe-Brecher für den Notfall.Es kann mit Gasaustrittssensor, Brandmelder oder anderen intelligenten Sensormodulen verbunden werden, so dass vor Ort oder fernab bei der Gasversorgung (manuell oder automatisch) abgeschaltet werden kann, wodurch die Sicherheit bei der Gasnutzung gewährleistet ist.das Ventil ist bei starker Vibration automatisch geschlossen.Nach dem Schließen ist ein manueller Betrieb erforderlich, um das Ventil einzuschalten.Diese Funktion entspricht den Sicherheitsvorschriften im Falle eines Unfalls.
Technical Data:
◆Suitable gas types: natural gas or non-corrosive gas etc
◆Closing modes: current impulse or manual
◆Driving Voltage: DC9-12V
◆Operating temp: -20℃~60℃
◆Sealing material: NBR rubber
◆Valve body material: copper alloy
◆Driving current：<1.5A (impulse)
◆Net Weight: 377g
◆Pressure max: 100kpa
◆Close time : <1 sec
◆Connection: DN20
◆Lead wire: 0.4m
◆Turn on manually
Working Principal:
When the switch is pressed, the capacitor discharges and provides an electric current so that a coil
can generate strong magnetic held to pull down the valve, achieving the closing within one second.
Operation instruction:
1.There are two ways to close the valve:
(a) An electric impulse of 1 sec (DC 9V), or
(b) Press the red knob (must open the protective cover first). After this operation, the valve remains closed.
Note: the protective cover must remain on position at all time.
2. When the valves is closed, manually pull the red knob up to turn it on, then the valve remains on.
Note: the valve may not to be pulled up if gas pressure on both sides (inlet and outlet) is not balanced.
Take necessary action to ensure that they are balanced, then pull the knob up again, force pulling it may result in damage to the valve.
3.The valve will close automatically when it detects strong vibrations. Should this feature fail, notify the contractor or manufacture for repair.
4. After closing, careful inspection is required. Do exercise caution when the valve needs to be turned on again.
