seat ensuring dependable bubble-tight shutoff of liquid or gas, and long service Typically, with swing check valves you are limited to the weight of the flapper or checking mechanism. When youre designing a system for automatic flow control the design of your check valve matters and the correct cracking pressure can be crucial. Spring loaded check valves can be built with springs to allow flow in any orientation while most swing checks are not suitable for flow vertical up or vertical down through the valve. This item is for use only in non-potable (non-human consumption) water applications.

Often measured in pounds per square inch (PSI), cracking pressure is the difference in pressure between the valves inlet and outlet ports. Your net cracking pressure will be the combination of the trim weight, the spring, and any fluid column above the check valve. If it is operating partially open the valve check mechanism may rattle and chatter, which can cause excessive wear and premature valve failure. Access My Account, Order History, Lists and more here. Something went wrong. If you install a spring-loaded check valve in a vertical flow up orientation, then the weight of the trim components would increase the amount of force required to open the check valve. Ultimately, if you need a check valve that will allow you to select the cracking pressure to meet the needs of your application, then a spring-loaded check valve is preferred. inc VAT. Seal Seat combines metal-to-metal contact with a resilient seal dependent, Check Crack Pressure: 1 to 2 PSI (.07 bar to .14 bar), Relief/Check Crack Pressures: 5 PSI (.35 bar), 10 PSI (0.7 bar), This item is restricted for conveying or dispensing water for potable use (human consumption).

We don't charge extra for back ordered lines! Swing check valves; however, use a flapper that swings off the seat to allow forward flow and then swings back to the seat when the flow is stopped (Learn more about the differences in spring-loaded check valves and swing check valves). Its also sometimes called the spring setting. Stainless steel check valves have fluorocarbon seats. 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. Additionally, the use of a spring check valve minimizes water hammer. Check valves are used in a wide range of industrial processes. If the flow direction is vertical down, gravity pulls the weight of the trim components against the valve spring. This reduces the net cracking pressure, which may cause the valve to open or fail to return closed. Enable JavaScript by changing your browser options, and then try again. In spring-loaded check valves the cracking pressure is determined by the spring setting and orientation of flow through the check valve. View cart for details. With spring-loaded check valves it may be possible for the spring (and the resulting net cracking pressure) to be tailored to the application. Working with a manufacturer that can tailor check valves to your application can be the difference between a low maintenance, properly functioning system, or one that requires frequent maintenance and sub-par performance.
