Delta-Elektrogas VMR VMR-OTN VMR 6 bar Safety Solenoid Valve

In industrial gas management, the speed and reliability of a shut-off system are non-negotiable. The VMR series is an automatic safety valve that remains closed by a spring when the electromagnetic coil is de-energized. Once powered, the valve opens instantly, allowing gas to flow. In the event of a safety trigger or power failure, the internal spring forces the valve to close in less than one second, preventing potential hazards.

The Delta-Elektrogas VMR VMR-OTN VMR 6 bar Safety Solenoid Valve is particularly noted for its mechanical strength and modularity. The VMR-OTN variants are specifically optimized for high-pressure scenarios, maintaining a bubble-tight seal even under significant backpressure. The valve body is constructed from high-grade die-cast aluminum, providing a lightweight yet extremely durable housing for internal components. Additionally, the modular design allows for the easy integration of visual indicators or closed-position indicator switches, giving maintenance teams real-time feedback on the valve’s status.

Description

The Delta-Elektrogas VMR VMR-OTN VMR 6 bar Safety Solenoid Valve is a high-performance safety shut-off solution engineered for the demanding requirements of gas combustion systems. Designed as a normally closed, fast-opening valve, it provides immediate gas flow interruption upon power loss, ensuring the highest level of protection for industrial burners and gas trains.
