Danfoss SVA-DH 250 angleway shut-off valve, 250 mm (10 in) butt weld ASME B 36.10M Schedule 40, steel, 40 bar, with handwheel (code 148B3767)
Danfoss · HVAC & Refrigeration · Globe Valves
Danfoss SVA-DH 250 angleway shut-off (stop) valve for industrial refrigeration, code 148B3767. Low-temperature steel body with butt-weld connections to ASME B 36.10M Schedule 40, nominal size 250 mm (10 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 High (SVA-DH) is the balanced design without restriction in the opening function; it opens at all differential pressures with limited torque. 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 handwheel. For HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) industrial refrigeration systems. PED category III.

Compatibility
Danfoss SVA-DH 250 large-size angleway stop valve for industrial refrigeration headers. Confirm line size (250 mm / 10 in), connection standard (ASME B 36.10M Schedule 40), top equipment (handwheel), and Delta-Pressure variant (SVA-DH) 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.
