(You can unsubscribe anytime), What You Need to Know about Check Valves and Cracking Pressure. Its the pressure differential required to crack open the valve (the point at which there is a sudden rise in flow). Food & Beverage Paper/Packaging Required fields are marked *. When youre designing a system for automatic flow control the design of your check valve matters and the correct cracking pressure can be crucial. Check valves are used in a wide range of industrial processes. Check valves prevent backflow into sump disposal lines, wastewater lines, sewage lift stations, and ejector systems. Additionally, the use of a spring check valve minimizes water hammer. Can you draw a sketch? I found this on the Surplus Center website, https://www.surpluscenter.com/.

I think you want a regulator, not a check valve. This can result in the check mechanism failing to operate, coming apart with components traveling up or downstream (which can destroy valuable equipment), and preventing the function of stopping reverse flow. AskEngineers is a forum for questions about the technologies, standards, and processes used to design & build these systems, as well as for questions about the engineering profession and its many disciplines. You know the equation for pressure (P = F/A), you know the equation for spring force (F = kx), you can measure the sealing area (A) now do the calcs, go on McMaster-Carr, and find the spring that you need.

My hope is that as the water turns to vapor, which is much less dense, it will expand in only one direction due to the check valves. In these cases, the spring selected must be heavy enough to support the weight of the trim, any column of liquid or media desired to be retained and achieve the minimum net cracking pressure. Please click on the following link to view the page: Copyright 2022 Surplus Center, All Rights Reserved. Most spring-loaded check valves have a minimum recommended net cracking pressure; however, the cracking pressure is affected by vertical flow orientation. Install it in your $0.50 check valve, and boom, you have a 15 PSI check valve. Some elements may not work properly.
