Product Description
Danfoss SV 3E float valve, code 027B0081 — the hydrocarbon (E) version of the SV 3 modulating liquid-level regulating (float) valve for industrial refrigeration. The float senses liquid level in a receiver or separator and modulates the orifice to hold a constant level. Flow coefficient Kv 0.14 m3/h (Cv 0.16). Maximum working pressure 28 bar (406 psig); maximum differential pressure 16 bar (232 psi). Balance-pipe connections 1 1/8 in solder or 1 in weld; pilot line OD 9.8 / ID 6.8 mm welding. Low-temperature steel body and float housing. Media temperature -50 to 65 C (-58 to 149 F). Approved for hydrocarbon refrigerants R1270, R170, R290, R600, R600a, RE170.
