VGD40.080U Siemens Gas Valve

Overview

The Siemens VGD40.080U is a high-capacity, normally closed double gas valve body designed for commercial and industrial burner systems. Featuring a compact modular design, it integrates two safety shut-off valves in series within a single housing, which simplifies gas train construction by reducing the number of fittings required. When combined with Siemens SKP series electro-hydraulic actuators, this valve provides essential safety functions, including shut-off, gas pressure regulation, and air-gas ratio control.

Features

• Double-valve design consists of two safety shut-off valves in series for enhanced safety
• High flow capacity achieved through double-seated valve construction
• Patented seat design with individual closing springs ensures reliable shut-off and a high close-off pressure rating
• Built-in stainless steel mesh inlet filter protects internal seats and downstream components from debris
• Dual stem guides provide precise disc alignment for a tight seal
• Modular compatibility allows the valve to be used with various SKP series actuators for diverse control functions
• Actuators can be mounted while the valve is installed and under pressure
