Frequently Asked Questions
It is primarily used to prevent backflow while mitigating the "water hammer" effect. In industrial settings, this protects expensive pumps and piping from pressure surges caused by sudden fluid stops.
The design separates the valve into two chambers. The first stage provides a fast shutoff to stop backflow, while the second stage uses a needle valve to slow the final closure, dissipating pressure gradually.
For extreme corrosion, such as seawater or chemical media, Stainless Steel 316 is the recommended choice due to its superior resistance compared to cast iron or brass.
Yes, the STORAEN Slow Closing Check Valve is designed for versatile installation and can be used in both horizontal and vertical orientations.
Yes, it is mandatory to install a Y-type or basket filter/strainer before the valve to prevent debris from interfering with the precision needle valve and sealing surfaces.
The 300X model offers a more streamlined disc design, which reduces pressure drop by approximately 25% compared to traditional swing-type valves, enhancing overall system energy efficiency.
