Description: Installation of the 2-Port Isolation Valve (2PIV) provides quick and easy refrigerant leak detection in evaporators, condenser coils, and refrigerant line sets. Valves are brazed on the ...

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

These graphs compare the pressure/flow characteristics of orifice and capillary restrictors. The characteristic impedance of an orifice restrictor does not vary linearly, so it will not always match ...
