Operational Design
The VGD40.080U is part of the modular Siemens combustion control family. It features a patented double-seat design that allows for high flow rates with minimal pressure drop. The valve body itself is passive and requires **SKP Series Electro-Hydraulic Actuators** (e.g., SKP15, SKP25, SKP50, SKP75) to operate.
Safety and Installation
This unit is rated **Class A** for safety shut-off applications. The housing includes multiple 1/4″ NPT pressure taps for connecting pressure switches or pilot lines directly to the body, eliminating the need for extra piping. It is essential for maintaining safety compliance in large boilers and furnaces.
