PRODUCT DESCRIPTION

HG-Stahl Axial Check Valves operate on the principle of preventing fluid flow up to a certain pressure by applying spring force in the opposite direction of the incoming fluid. Compared to other check valves, they can serve high-pressure applications in a wafer-type structure due to the stronger spring force applied.

A drawback of HG-Stahl Axial (Axial) Check Valves is that the valve body and spring obstruct the fluid path, leading to pressure loss within the system.

HG-Stahl Axial Check Valves are manufactured according to our standards but can also be customized to the dimensions specifically requested by the user. HG-Stahl Engineering provides high-quality and fast solutions tailored to different applications for industries such as chemical, cement, oil, gas, natural gas, mining, steel, and energy.

For special design axial valves, materials are carefully selected according to the acidic value of the fluid, ensuring that the valves can operate for many years.

In addition to standard steel or stainless-steel materials, other materials with unique properties can be requested. Some of the materials we can provide to our partner companies include Titanium Alloys (Titanium Gr.2, Gr.3, Gr.5, Gr.6, Gr.7, Gr.12), Zirconium Alloys (Zirconium 702, 705), Bronze Alloys (C95800, C95500, C95400, C63200), Nickel Alloys (Inconel 600, 625; Hastelloy B, B-2, B3, C276, C-22, C-4, G; Incoloy 800, 800H, 825; Monel 400, K500; Nickel 200, 201), Duplex Stainless Alloys (C95800, C95500, C95400, C63200), and Aluminum Bronze products.

Thanks to its design that optimizes the fluid’s movement within the valve, the HG-Stahl Axial Check Valve minimizes the risk of cavitation during flow. Cavitation occurs in areas where high-pressure differences cause the fluid to vaporize, damaging the surfaces of the valve and the pipeline. This can result in rapid deformation, even for newly installed valves. HG-Stahl axial check valves ensure a smooth transition in the flow direction, balancing sudden pressure changes and completely preventing these adverse effects.

This feature not only extends the valve’s service life in high-pressure systems but also reduces potential maintenance requirements. Designed and manufactured by HG-Stahl, these check valves offer long-lasting performance under challenging conditions, enhancing the efficiency of facility operations.
