Overview
The Siemens VGG10.204P is a high-quality, single-body gas valve designed for integration into gas trains for commercial and industrial burners. It is a normally closed, 2-port safety shut-off valve that complies with EN 161 standards when paired with appropriate actuators. Featuring a die-cast aluminum body and a profiled (contoured) valve disc, it is specifically engineered to provide superior control performance and stable regulating behavior, particularly in low-fire ranges where it is less prone to hunting.
Features
- Profiled valve disc ensures precise gas flow control and excellent regulation performance
- Integrated stainless steel mesh strainer protects the valve seat and downstream components from dirt and debris
- Normally closed design provides reliable safety shut-off functionality
- Dual stem guides guarantee precise disc alignment and tight shut-off
- Modular design allows for the mounting or replacement of actuators while the valve remains under pressure
- Equipped with four Rp 1/4 inch test points for pressure monitoring
Specifications
- Model: VGG10.204P
