Normal butterfly valve with open position
Decoupler can be both directional either to or fro and it is motorised butterfly valve.
Where air and water are brought into direct contact with each other in order to reduce the water's temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the chiller to control flow as per water circulation normal or motorized isolation valve is used.
A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water's temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.
Motorized, the BMS expert can explain the controls behind the motorized valve.
Motorised butterfly valve as it has bi-directional function.
butterfly valve ,it should be open position.we can adjust flow rate with secondary pumps.
this is like a bypass line to control flow between primary and secondary pump line
Normally primary pump are constant speed and secondary variable so extra flow goes as by pass through decoupler
Decoupler has Bi-directional motorised butterfly valve.
