SV 1 / SV 3

Several float valves are available for Industrial refrigeration liquid level control in the product group “Liquid level regulating valves”, such asHFI and SV series. The SV series contains the following types: SV 1, SV 3, SV 4, SV 5 and SV 6, some of which can be delivered as dedicated“E” versions for hydrocarbon application.The SV 1 and SV 3 can be used separately as a modulating liquid level regulator in refrigerating, freezing and air conditioning systems for ammonia or fluorinated refrigerants. However, in most cases, the SV is used as a float pilot valve for the main expansion valve type PMFH.The SV 1 and SV 3 are used as liquid level regulators in either low pressure applications or in high pressure applications. Adaptation to the specific application is done by the orientation of the valve and thereby the float functions.
