Solenoid valves for gas - safety and control for modern gas systems You need a reliable solution for automatically shutting off or releasing gas in your system? Solenoid valves for gas offer a high level of safety, control and convenience - in industrial as well as commercial and private applications. They regulate the gas flow electromagnetically and are used wherever gases need to be supplied or interrupted in a controlled manner - be it in heating systems, gas stoves, burner controls or automated safety systems.
What is a solenoid valve for gas and how does it work? A solenoid valve for gas is an electrically operated valve that automatically opens or closes the gas flow in a pipe. It essentially consists of a valve body and an electromagnetic coil that generates a magnetic field when an electrical voltage is applied, thereby moving the valve mechanism. In the de-energized state, the valve remains either closed (normally closed, NC) or open (normally open, NO), depending on the design. This allows the valve to be actively controlled, for example by thermostats, timers or leakage sensors - without any manual intervention.
Where are solenoid valves for gas used? Solenoid valves are used wherever gases need to be automatically controlled or safeguarded. Common applications include gas condensing boilers, industrial ovens, commercial kitchens, emergency shutdowns in buildings and central control systems in gas distribution systems. In heating systems, they are used to enable the flow of gas only when operation is enabled, while they close automatically in the event of a fault or power failure, thereby increasing safety.
In safety-relevant applications in particular, it makes sense - and is sometimes mandatory - to combine a solenoid valve with a gas flow monitor. The gas flow monitor monitors the gas flow and detects unusually high flow rates, such as those that can occur in the event of a leak or defect. In conjunction with a solenoid valve, the gas flow can then be interrupted immediately to avoid dangerous situations.
What are the advantages of solenoid valves for gas? Solenoid valves offer precise control of the gas flow, high operational safety and a fast response time in the event of faults or emergencies. They can be easily integrated into existing systems and connected to control or monitoring units. The great advantage lies in their automation capability - both for control and for protection. By combining them with sensors and gas flow monitors, a comprehensive safety concept can be implemented that maximizes both personal and system protection. In addition, solenoid valves are low-maintenance and durable, especially when high-quality materials and components are selected.
What needs to be considered when selecting a solenoid valve for gas Several factors play an important role when selecting a solenoid valve for gas. The type of gas, the desired operating pressure, the pipe diameter and the operating mode (e.g. normally closed or open) are decisive. The ambient temperature, switching behavior and switching frequency should also be taken into account when making the selection. Conformity with relevant standards (e.g. DVGW, ATEX) must also be ensured, especially for commercial and industrial applications. For particularly safety-critical applications, the use of valves with integrated or externally combinable gas flow monitors is recommended.
