Danfoss SNV Gauge Valves
SNV gauge (service) valves are built for servicing heavy-duty industrial refrigeration applications. Two versions are available: SNV-ST in low-temperature steel and SNV-SS in stainless steel, each in standard and extended-branch configurations (extension 50—150 mm).
SNV-ST and SNV-SS are approved by Danfoss for use with more than 70 R-numbers: HCFC, non-flammable HFC, R717 (ammonia), R744 (CO2) and hydrocarbons.
