Threaded excess flow check valves are used where the valve has to be screwed to the mechanism of the application such as for connections in pipelines.
There are numerous sizes of threaded type valves available to meet specific requirements. The valve can have a male connection, a female connection or both male and female connections. Threaded type valves with a male connection can be used in tanks with threaded nozzles.
Here, pressure equalisation takes place through the check mechanism of the valves. To ensure durability and reliable construction, threaded type excess flow check valves are made using stainless steel or carbon steel.
