VGG10.504U Siemens Gas Valve

Overview

The Siemens VGG10.504U is a high-quality, single-body gas valve designed for safety shut-off, gas pressure regulation, and air-gas ratio control in commercial and industrial burner systems. This normally closed valve is engineered to work in conjunction with Siemens SKP series electro-hydraulic actuators. Constructed from durable die-cast aluminum, it provides a reliable and efficient solution for managing gas flow while meeting strict safety standards including UL, FM, and CSA certifications.

Features

• Integrated stainless steel mesh filter (0.8 mm to 0.9 mm) protects the valve seat and downstream components from contamination
• Dual stem guides ensure precise disc alignment and provide tight shut-off for enhanced safety
• Contoured valve disc design allows for stable regulating control and smooth release of gas
• Includes 1/4 inch NPT pressure taps on both the inlet and outlet for easy monitoring and testing
• Modular design allows for easy mounting of SKP series actuators even while the valve is installed and under pressure
• Slow-opening and rapid-closing mechanism when paired with compatible actuators to prevent pressure surges
