Description

The ADCA PS47 pilot operated pressure sustaining valves are designed for use on steam, compressed air, nitrogen and other gases compatible with the construction and they can be installed throughout all industries.
The pressure sustaining valves are particularly recommended in those systems where a limited flow rate is available and it is necessary to guaranty the supply to some critical process applications. Installing this valve in the supply of non-critical application limited to the minimum required pressure, they will close in case of excess of consumption and consequent pressure drop in the system, keeping the remaining flow available for the critical application.
In general this valve maintains the upstream pressure under control.
Connections are flanged or threaded.
