Check valves are self-working security valves that allow liquids and gases to flow in just single direction. The objective of a check valve is to stop process flow form reversing in the system which could destroy equipment or upset the process. They are top secret as single-way directional valves. These valves are generally found saving pumps in liquid functions or compressors in gas systems where backflow could cause the compressor or pump to shut down. They are also applied in process systems that have varying forces, which must be kept separate. They do not want an outside power supply to operate since they use the force drop created by the media flow.

Our Check valves applications
Stainless steel check valves are generally used when different gases mixed into single gas stream. A check valve is installed on each of the individual gas streams to stop mixing of the gases in the real source. For example, if a fuel and an oxider need to be mixed, then check valve will generally be used on both the oxidiser and fuel sources to make sure that the real gas cylinders remain pure and so non-flammable.
Hydraulic check valve check valves are used with some kinds of pumps. Diaphragm pumps and piston-driven pumps, such as pumps metering and chromatography pumps, generally use outlet and inlet ball check valves. These valves generally look like little cylinders linked to the pump head on the outlet and inlet lines. Many similar pump-like mechanisms for moving volumes of fluid around use check valves such as check ball valves.
Our check valves are also used in many fluid systems, such as those in power and chemical plants. Typical applications in the nuclear industry contain feed water control systems, make-up water, dump lines, miscellaneous process systems, N2 systems, sampling and monitoring systems. In aerospace and aircraft, check valves are applied where top vibration, big temperature increases and corrosive fluids are in attendance.
