quick disconnect coupling

quick disconnect coupling Quick disconnect coupling is composed by two parts--the socket and the plug. It is also called the male part and the female part. Quick disconnect coupling is for general purpose, medium pressure. 1.Quick disconnect coupling has two-way shut-off with an automatic shut-off valve incorporated into the both socket and the plug. 2.Quick disconnect coupling has automatic shut-off vales in socket and plug provide an instant, perfect seal when coupling is disconnected. 3.Quick disconnect coupling packing be selected according to fluid type. 4.Quick disconnect coupling: highly accurate machining technology creates an extramely tight seal. 5. Quick disconnect coupling is designed for a wide varity of applications. For the water, the hot liquid, the oil, acid, alkaliand the salty water. 6.Quick disconnect coupling is made of the stainless steel 304#. It has a lot of size. for example, 1/4'' , 2/8'', 1/2'', 3/4'', 1'', 11/4'', 11/2'' and 2''. Applications: 1. Water piping, sea water, beer and other liquid food 2. Oxygen, acetylence 3. Steam piping 4. Chemicals, checmical plants 5. High-presure gas structure When disconected the socket and plug valves seal instantly, automatically shutting off fluid flow to prevent leakage. When connected the socket and plug valves push together, opening to permit free flow of fluid through coupling. An O-ring in the socket seals the plug surface preventing any leakage.
