Danfoss · HVAC & Refrigeration · Needle Valves
Danfoss SNV-ST gauge valve (a stop needle valve configured for pressure-gauge, purge, charging and isolation points, with parallel-thread G connections on both ends) for industrial-refrigeration service, code 148B3745. The SNV series is a hand-operated stop/needle service valve with a sturdy back-seating (metal-to-metal) spindle; it needs no specific flow direction (bi-flow) and gives favourable, throttleable flow characteristics. This SKU has G 1/2 A (external, parallel) inlet x G 1/2 A (external) outlet connections to ISO 228/1. Housing and bonnet are low-temperature steel, built to the Pressure Equipment Directive. Maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). Applicable to HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2). Specifications per Danfoss store code 148B3745.

Compatibility
Danfoss SNV stop/gauge needle valve. Select by connection type and size (here G 1/2 A both ends) and by housing material — SNV-ST is low-temperature steel (52 bar / -60..150 C) and SNV-SS is stainless steel (65 bar / -60..200 C) for corrosive or higher-duty service. Each connection combination is a separate order code; confirm port type and size before ordering. Compatible with HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) refrigeration systems.
