VGG10.204P Siemens Gas Valve

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
• Connection: 3/4 inch BSP (Internally threaded)
• Maximum Operating Pressure: 1200 mbar (approx. 17.4 psi)
• Flow Rate: 8.9 m3/h (at delta p = 1 mbar)
• Valve Class: Class A according to EN 161

Applications

• Primary safety shut-off valve in gas trains for forced draft burners
• Precision gas flow control in industrial combustion plants and boiler systems
• Used in combination with SKP series electro-hydraulic actuators (e.g., SKP15, SKP25, SKP55, or SKP75) for shut-off and pressure regulation
• Applicable for use in supply air lines of industrial combustion equipment with or without heat recovery systems
