Check Valves

Check valves are used to prevent backflow within a pipeline system in order to protect pipeline equipment which may be susceptible to damage from backflow.

There are a variety of mechanisms which check valves can utilise to prevent back flow, these can include; discs, pistons or balls. Generally speaking all of these mechanisms also utilise a spring to assist with the closure of the valve.
