VGG10.654U Siemens Gas Valve

Overview

The Siemens VGG10.654U is a high-capacity, single-body gas valve designed for safety shut-off and control in commercial and industrial burner systems. This 2-1/2 inch NPT threaded valve is typically used in combination with Siemens SKP series electro-hydraulic actuators to provide functions such as safety shut-off, gas pressure regulation, and air/gas ratio control. Its normally closed design ensures a tight seal, while the modular architecture allows for flexible system integration and simplified maintenance in high-demand combustion environments.

Features

• Modular design allows for seamless pairing with all SKP series actuators for various control functions
• Integrated stainless steel mesh inlet filter protects the valve seat and downstream components from contamination
• Dual stem guides ensure precise disc alignment for consistent, tight shut-off
• Contoured valve disc provides a smooth release of gas and stable regulating control across its operating range
• Built-in 1/4 inch NPT pressure taps on both the inlet and outlet for easy system monitoring
• Robust cast iron body construction designed to withstand harsh industrial conditions
