VGG10.154U Siemens Gas Valve

Overview

The Siemens VGG10.154U is a high-performance, normally closed single-body gas valve designed for use in commercial and industrial burner applications. Constructed from durable die-cast aluminum, this 1/2-inch NPT threaded valve serves as a modular component that, when paired with Siemens SKP series electro-hydraulic actuators, provides essential safety shut-off, gas pressure regulation, and air-gas ratio control. Its robust design ensures reliable operation and precise flow control in demanding heating systems.

Features

• Robust die-cast aluminum body construction for long-term durability
• Integrated stainless steel mesh strainer (0.8 mm to 0.9 mm) protects the valve seat and downstream components from contamination
• Dual stem guides ensure precise disc alignment and reliable tight shut-off
• Contoured valve disc design provides smooth gas release and stable regulating control
• Four 1/4-inch NPT pressure taps (tappings) for convenient inlet and outlet monitoring
• Versatile mounting capability allowing installation in any position except upside down
• Agency certified with UL listing, FM approval, and CSA certification when used with compatible actuators
