148B3746 Danfoss SNV-ST Gauge Valve, 1/4" MPT x 1/4" FPT

SNV gauge valves 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 is applicable to HCFC, non flammable HFC, R717 (Ammonia) and R744 (CO2).

Features:

• Suitable for “heavy duty” industrial applications having a very sturdy and safe design including high pressures and wide temperature range.
• The SNV-ST and SNV-SS valves have back seating (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 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.
