Air Conditioner and Refrigeration Compressor Rotolock Valve
Rotolock valve is a special refrigeration valve with a seal ring seated against a machined surface enclosed by a threaded fitting; this valve allows the technician to remove all refrigerant from the compressor without requiring removal of the system charge.
Rotolock valves are designed for installation of compressor and receivers in commercial AC&R system which helps to reduce service repair time in case of compressor failure and during maintenance shutdown periods. Rotolock Valve designs provide quick disconnection and isolation of low and high side of refrigeration system during maintenance periods.
