Description
ARC Recirculation Valves
Should the pump main flow change and reduce, the valve will open mechanically to a bypass min flow as per pump manufacturer specifications.
Resulting in perfect control and most importantly protecting the pump against potential damage.
Operational.
The main Flow moves the check valve, which is connected via a lever assembly to the Bypass Modulating system. The valve in the natural position (meaning the Main Flow valve is closed) will open the Bypass valve fully, this will allow the required minimum flow according to the pump manufacturer’s specifications and will control the delivery pressure down to suction pressure.
Opening the Main Flow control valve will result in an increased flow in the ARC valve, this will lift the check valve resulting in the Bypass valve closing proportionally. The Bypass valve will be fully closed when the check valve reaches maximum travel. Maximum travel is normally reached at 30% max. Flow pending pump specifications.
ARC Valve Bypass design will be selected pending pump pressure (Pump Head) and suction pressure and Flow.
