Delta-Elektrogas EVRM -NC -NA Safety Solenoid Valves

Safety and precision are at the core of the EVRM series. These valves operate through a manual reset mechanism, meaning that once the valve is triggered and gas flow is shut off, it requires a deliberate manual action to restart the supply. This feature ensures that gas flow cannot resume until the cause of the emergency signal has been identified and resolved by a qualified technician.

The technical design of the Delta-Elektrogas EVRM -NC -NA Safety Solenoid Valves allows them to handle high-pressure environments while maintaining a bubble-tight seal. The NC (Normally Closed) version remains open when energized and closes immediately upon power loss or signal trigger. Conversely, the NA (Normally Open) version stays open and only closes when a momentary pulse or continuous signal is received, making it highly energy-efficient for specific safety protocols. Built with a die-cast aluminum body and high-grade internal components, these valves are designed to withstand industrial rigors while offering long-term reliability without the need for constant maintenance.

Description

The Delta-Elektrogas EVRM -NC -NA Safety Solenoid Valves are high-reliability manual reset safety devices designed to secure gas lines in industrial and commercial environments. These valves act as a critical fail-safe, cutting off gas supply instantaneously when triggered by a leak detector or safety signal, ensuring maximum protection for personnel and infrastructure.
