A check valve, clack valve, non-return valve or one-way valve is
a mechanical device, a valve, which normally allows fluid (liquid
or gas) 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 a wide variety of
applications. Check valves are often part of common household
items. Although they are available in a wide range of sizes and
costs, many check valves are very small, simple, and/or cheap.
Check valves work automatically 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 are made of plastic or 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 is designed for and can therefore be
specified for a specific cracking pressure.
