Description: Check valves are also known as clack valves, non-return valves, reflux valves, or retention valves. Their function is to allow the flow of fluid in a single direction. Check valves have two ports, one for fluid inflow and the other for fluid outflow. Check valves are used in many applications and are usually simple in design small, affordable and can be found in many household gadgets. They are mostly made of metal or plastic, and they work automatically without external or personal supervision. The types of check valves include diaphragm valves stop-check, lift check, ball check, swing check, duckbill, and pneumatic non-return valves. The closing member in ball part check valves is a ball while in diaphragm checks valves, a flexing rubber creates a normally- closed valve. Check valves are used in pumps, industrial processes, and in domestic use. Metering pumps are a type of diaphragm pumps that resemble small cylinders attached to inlet and outlet sides of the pump head.We stock a wide range of check valves to suit various applications.
