HSX high pressure float valves have a shut-off valve welded onto the inlet as well as onto the outlet, as well as a vacuum nozzle and an externally operated transport lock / manual adjustment that can be operated from the outside. In addition, service valves for emptying and discharging non-condensable gases can be installed via two G¼” threaded connections. Depending on the intended regulation values, the size of the outlet aperture is mechanically opened by means of a float operated valve. The condensed refrigerant is released from the high-pressure side to the low-pressure side and returned to the reservoir. The transport lock must be “released” before use; this mechanical design operates without electrical power and regular maintenance intervals are not required. When ordering: – Please specify the intended regulation aperture (-X, -H, -M, -L), the refrigerant type and the application (Qo, to ,tc).
