VGF10.654P Siemens Gas Valve

Overview

The Siemens VGF10.654P is a high-performance, single-port gas valve body designed for use in gas trains for gas-fired combustion plants and forced draft burners. This 2.5-inch flanged valve is a Class A safety shut-off device when paired with Siemens SKP series electro-hydraulic actuators. It features a normally closed design and a contoured disk (profile) to provide precise linear flow control, making it suitable for both shut-off and regulating applications.

Features

• Built-in stainless steel strainer with 0.9 mm mesh size to protect the valve seat and downstream components
• Contoured disk design (type suffix P) for optimized flow characteristics and precise control
• Robust cast iron construction for durability in industrial environments
• Versatile mounting positions when combined with compatible actuators
• Rapid closing and slow opening functionality for enhanced system safety
• Dual test points (Rp 1/4) and pilot gas connections (G 3/4) for simplified monitoring and installation
