Special Features :Check Valve is a Mechanical device, a valve that normally allows a fluid to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in wide variety of applications. Although they are aviliable in a wide range of sizes and costs, many check valves are very small and simple/ or cheap. Check Valves work autometically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves or made of metal
An important Concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve ia designed for and can therefore be specified fpr spacific cracking pressure
