VGG10.254U Siemens Gas Valve

Overview

The Siemens VGG10.254U is a high-performance, normally closed single-body gas valve designed for commercial and industrial burner applications. Built with a durable die-cast aluminum body, this 1-inch NPT threaded valve is engineered to work in modular combination with Siemens SKP series electro-hydraulic actuators. This combination allows for a variety of critical functions, including safety shut-off, gas pressure regulation, and air-to-gas ratio control, while reducing the overall size and weight of the gas train.

Features

• Modular design compatible with all SKP series actuators (SKP15, SKP25, SKP55, and SKP75)
• Integrated stainless steel mesh inlet filter to protect the valve seat and downstream components
• Contoured valve disc ensures stable regulating control and smooth gas release
• Dual stem guides provide precise disc alignment for reliable, tight shut-off
• Four 1/4-inch NPT pressure tappings (two on the inlet and two on the outlet)
• Capable of being serviced or having actuators mounted while the valve is under pressure
