Danfoss SV 5 float valve, code 027B2025 — modulating liquid-level regulating (float) valve for industrial refrigeration using HCFC, HFC or R717 (ammonia). The float senses liquid level and modulates the orifice to hold a constant level. Flow coefficient Kv 0.31 m3/h (Cv 0.36). Maximum working pressure 28 bar (406 psig); maximum differential pressure 21 bar (305 psi). Inlet 21.8 mm; balance-pipe weld connection 1 in. Steel body and float housing. Media temperature -50 to 120 C (-58 to 248 F).
