In large-scale industrial heating, the controlled introduction of fuel is vital for system longevity and safety. The VMH series operates as a normally closed safety valve that stays shut via a powerful return spring. When energized, the internal hydraulic pump builds pressure to open the valve disc slowly and steadily. This slow-opening characteristic is fully adjustable, allowing operators to fine-tune the burner start-up sequence to prevent flame instability or structural stress on the combustion chamber.
A primary technical advantage of the Delta-Elektrogas VMH Safety Hydraulic Valves is the immediate safety response; in the event of a power failure or a signal from the Burner Management System (BMS), the valve closes in less than one second. The valve body is manufactured from high-grade die-cast aluminum or cast iron for larger sizes, ensuring it can withstand significant mechanical loads. Furthermore, its modular design supports the integration of various accessories, including closed-position indicator switches (CPI) and visual position indicators, making it a highly versatile component for complex gas train architectures.
The Delta-Elektrogas VMH Safety Hydraulic Valves are high-capacity, slow-opening safety shut-off valves designed for industrial gas burners and large-scale combustion plants. Utilizing a sophisticated hydraulic actuator, this valve ensures a smooth and adjustable opening sequence, providing maximum protection against pressure shocks during ignition while maintaining a rapid fail-safe closure.
