Product Summary

Alarm check valve is a check valve with the device of alarm, which can signal while the condition, such as pressure or temperature, is beyond the limitation of the valve body. Alarm check valves re two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. The bodies (external shells) of most alarm check valves are made of plastic or metal. An important concept in alarm check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the alarm check valve is designed for and can therefore be specified for a specific cracking pressure. 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.

Alarm check valves are used for a wide variety of applications. They are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, and/or inexpensive. Check valves are often used with some types of pumps. Piston-driven and diaphragm pumps such as metering pumps and pumps for chromatography commonly use inlet and outlet ball check valves. These valves often look like small cylinders attached to the pump head on the inlet and outlet lines. Many similar pump-like mechanisms for moving volumes of fluids around use check valves such as ball check valves. And alarm check valves are also used in many fluid systems such as those in chemical and power plants, and in many other industrial processes.
