Where to Buy

The Parker Bestobell’s flow diverters allow for quick and effective changeover between relief valves. They ensure that the flow capacity of the valve is not reduced below that available from one fully open port.

Safety Warning

Full Product Description

Parker Bestobell offers flow diverters in two formats: ball or globe valve.
These flow diverters enable quick and safe changeover between relief valves. They ensure that the flow capacity of the valve is not reduced below that available from one fully open port, even during movement of the operating lever from one position to another. The integrity of the vessel is not threatened, even if the operator inadvertently leaves the operating lever mid-position.
As the valve is normally at the hub of a fairly complex piping system, there are many variations available on the basic design available to meet customers’ specific requirements.
These flow diverters are designed for use with Group 1 gases and manufactured in accordance with ASTM B31.1, BS EN 1626 and BS ISO 21011. They should be used in conjunction with Parker’s thermal relief valve.
