PFA lined ball valves with spring return handles| CRP US
The Atomac range of ball valves with spring return operating handles up to 3”NB (AKH3) are available from CRP.
Spring return handles (commonly known as dead man’s handles) ensure that the valve cannot be left open or closed. The operator must maintain opening pressure on the handle to operate the valve, as soon as the handle is released the powerful spring mechanism ensures that the lined ball valve returns to its natural un-operated state.
The spring return mechanism is totally encapsulated preventing the ingress of dust and makes for a longer working life. As well as fully assembled valves we can also supply the spring return handle and mounting kit separately for assembly to existing Atomac ball valves on site.
