Product Description
Danfoss SVA-DL 300 angleway shut-off (stop) valve for industrial refrigeration, code 148B3770. Low-temperature steel body with butt-weld connections to EN 10220, nominal size 300 mm (12 in). Maximum working pressure 40 bar (580 psig); media temperature range -60 to 150 C (-76 to 302 F). Flow coefficient Kv 1610 m3/h (Cv 1867.6 gal/min). Delta Pressure Low (SVA-DL) is a two-step valve for pressure relief, designed with a restriction in the opening function (high differential pressure applied from the side port, reduced pressure from the bottom port). Both SVA-DL and SVA-DH have internal backseating, so the spindle seal can be replaced while the valve is still under pressure; the valve dismantles in line for inspection and repair. Supplied with cap. For HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) industrial refrigeration systems. PED category IV.

Compatibility & Fitment
Danfoss SVA-DL 300 large-size angleway stop valve for industrial refrigeration headers. Confirm line size (300 mm / 12 in), connection standard (EN 10220), top equipment (cap), and Delta-Pressure variant (SVA-DL) before ordering: SVA-DL has a restriction in the opening function for two-step pressure relief, while SVA-DH is balanced for opening at any differential pressure. SVA-DH and SVA-DL share spindle/seat servicing in line.
