VGG10.154P Siemens Gas Valve

Overview

The Siemens VGG10.154P is a high-quality, single-body gas valve designed for safety shut-off and precise control in gas-fired combustion systems. Part of a modular system, this 1/2-inch BSP threaded valve is engineered for integration with Siemens SKP series electro-hydraulic actuators. It features a die-cast aluminum body and a specialized profiled seat (contoured disk) that ensures stable regulating control and superior performance, particularly in low-fire operating ranges.

Features

• Profiled seat (contoured disk) provides smooth gas release and minimizes hunting during low-fire operation
• Integrated stainless steel mesh strainer (0.9 mm) protects the valve seat and downstream components from contamination
• Normally closed, 2-port globe valve design for safety shut-off applications
• Dual stem guides ensure precise disc alignment and reliable tight shut-off
• Modular design allows for the mounting of various actuators while the valve is under pressure
• Robust die-cast aluminum construction suitable for industrial environments
• Includes four Rp 1/4″ test points for pressure monitoring
