What is a arc valve?
The Automatic Recirculation Control (ARC) valve is a self contained, low maintenance and reliable device, engineered to protect centrifugal pumps against thermal damage and destruction.
What is the purpose of the recirculation valve?
Automatic recirculation valves, sometimes referred to as pump protection valves or minimum flow valves are installed on the outlet of a centrifugal pump discharge line. Their purpose is to prevent the pump from overheating by ensuring that there is a minimum flow through the pump at all times.
Where is the recirculation valve?
What is the Recirculation Valve? The recirculation valve is operated from the depression in the air inlet, upstream of the turbo and downstream of the throttle valve.
What is recycle valve?
Valve purpose Compressor recycle valves are used to recycle gas flow from the compressor discharge to the suction and prevent operation below the surge point. The valve protects the compressor from the destructive effects of low-capacity operation when the surges of flow reversal can actually destroy the compressor.
Where does a recirculating valve go?
The recirculation valve is operated from the depression in the air inlet, upstream of the turbo and downstream of the throttle valve.
What valve is best for throttling?
Among the most common valves, the butterfly valve is the most suitable for throttling. A full quarter turn can open or close the valve. For throttling to happen, it only needs to open a bit for the media to pass.
Where is the arc valve on a pump?
The ARC valve is installed in the pump discharge line in the position of the main check valve it replaces. It is adaptable to horizontal or vertical piping and to either horizontal or vertical upward flow. Flanged or welded ends are optional to suit specifications.
What are the features of yarway arc protection valves?
YARWAY ARC PUMP PROTECTION VALVES (AUTOMATIC RECIRCULATION) SERIES 9200, 9100, 5300 AND BPR FEATURES • Precise recirculation control. • Stable design. • Integral check valve. • Low maintenance.
What is the difference between centrifugal pump and arc valve?
The modern industrial equipment process request centrifugal pump basically works under the condition of variable flow. An automatic recirculation valve (ARC valve) is a multifunctional valve whose primary purpose is to ensure that a pre-determined minimum flow is assured through a centrifugal pump at all times.
What is the BPR number for arc pump protection valves?
