Danfoss Gauge Valve - Type SNV-ST and SNV-SS
For servicing of heavy-duty industrial refrigeration applications
SNV stop gauge are designed as service valves with a very sturdy construction. SNV-ST are made in steel approved for low temperature operations, SVA-SS are stainless steel versions.
SNV valves have internal backseating (metal to metal), enabling the spindle seal to be replaced while the valve is still under pressure.
SNV-ST and SNV-SS are available in standard branch length configuration as well as extended branch configuration, with extension length versions from 50 to 150 mm.
Features:
- Applicable to HCFC, non flammable HFC, R717 (Ammonia), R744 (CO2) and hydrocarbons
- Suitable for "heavy duty" industrial applications including high pressures and wide temperature range
- The SNV-ST and SNV-SS valves have backseating (metal to metal)
- Compact and light valve for easy handling and installation
- No special flow direction required
- Provide high flow characteristics
- Each valve type is clearly marked with type and size
- Housing and bonnet material is low temperature steel (stainless steel for SNV-SS) according to requirements of the Pressure Equipment Directive and other international classification authorities
- Valve safety is enhanced with the spindle being secured such that it cannot be unscrewed
- Standard versions available with Max. operating pressure ranges (see Ordering section):
- 52 bar / 754 psig Valves
- 65 bar / 943 psig Valves
- 140 bar / 2030 psig Valves
- Full temperature range:
- SNV-ST: -60 – 150 °C / -76 – 302 °F
- SNV-SS: -60 – 200 °C / -76 – 392 °F
- Classification: DNV, CRN, BV, EAC etc.
