VGD40.065U Siemens Gas Valve

Overview

The Siemens VGD40.065U is a high-capacity, normally closed double gas valve body designed for use in commercial and industrial burner systems. It consists of two safety shut-off valves in series within a single compact housing. Engineered for reliability and safety, this modular valve body is designed to be paired with Siemens SKP series electro-hydraulic actuators to provide functions such as safety shut-off, gas pressure regulation, and air-to-gas ratio control.

Features

• Compact double-valve design reduces the overall footprint and weight of the gas train
• Each individual safety shut-off valve features double seats to achieve high flow rates
• Patented seat construction includes individual closing springs for each seat to ensure reliable shut-off
• Integrated stainless steel mesh inlet filter protects valve seats and downstream components from debris
• Modular architecture allows for the mounting of actuators while the valve is under pressure
• Equipped with 1/4 inch NPT pressure taps on the inlet, outlet, and between the main valves
