VGG10.204U Siemens Gas Valve

Overview

The Siemens VGG10.204U is a high-performance, normally closed single-body gas valve designed for commercial and industrial burner applications. Constructed from die-cast aluminum, this 3/4-inch NPT threaded valve is engineered to work in conjunction with Siemens SKP series electro-hydraulic actuators. Depending on the actuator used, the assembly provides critical functions such as safety shut-off, gas pressure regulation, and air-gas ratio control. It features a contoured valve disc to ensure stable regulating control and a smooth release of gas, making it a reliable component in complex gas trains.

Features

• Modular design allows for integration with various SKP series actuators for diverse control functions
• Integrated stainless steel mesh inlet filter protects the valve seat and downstream components from debris
• Contoured valve disc provides precise regulating control and smooth gas release
• Dual stem guides ensure accurate axial stroke and tight shut-off performance
• Includes 1/4-inch NPT pressure taps on both the inlet and outlet for easy monitoring
• Durable die-cast aluminum body suitable for rigorous industrial environments
• Capable of being mounted in any position except upside down
