The operation of the EV series centers on a normally closed (NC) fail-safe mechanism. When the solenoid coil is energized, the valve opens, allowing fuel oil to flow to the burner. Upon power interruption—whether by a control signal or a safety interlock—the internal spring immediately forces the valve to close in less than one second. This rapid shut-off capability is critical for preventing fuel leakage and protecting the plant from potential fire hazards.
What distinguishes the Delta-Elektrogas EV Oil Valves in the market is their specialized internal design, which is optimized for oil viscosity. Unlike standard gas valves, the EV series features seals and components specifically treated to withstand the chemical properties of light and medium oils. The valves are built with a die-cast aluminum or brass body (depending on the model) and are equipped with a fine-mesh suction filter to protect the valve seat from particulates. This ensures a clean seal every time the valve closes, extending the service life of the entire oil train and reducing the need for frequent maintenance.
The Delta-Elektrogas EV Oil Valves are high-reliability safety shut-off devices designed specifically for oil-fired burners and industrial heating systems. These electromagnetic solenoid valves provide instantaneous fuel cut-off to prevent accidents and ensure the safe operation of combustion equipment handling light and medium fuel oils.
