Horizontal Check Valves

These check valves are the standard 1-way flow application to prevent moisture in a nitrogen (N₂) line and keep the gases flowing, literally horizontally/vertically, with no backflow. The valves are installed directly in the pipe and are typically used to do any of the following: discharge backflow out of the system, pushes liquid or gaseous material 1-way with efficiency (straight piping product) or in a filtration scenario where damage may occur unless you control liquid/gas directions away from a bulk tank or manifold system. The Evergreen Sales Team would like to highlight key features that make this product line unique compared to other check valves:
