3 & 4-Way Mixing Valves

Transcription

1 & 4-Way Mixing Valves -Way Valve Applications / Features: The ESBE MG series of & 4-way valves are designed to mix water to the appropriate temperature to meet the zone or requirements within heating and cooling s. Through means of mixing or diverting, the fluid temperature leaving the valve is regulated by the MG. The valves are designed to operate within closed loop s through manual operation or automatically when used with the 60 or 90 Series electronic motor actuator that is typically connected to an outdoor reset controller, DDC or boilers with integrated controls. Features: MG series mixing valves are a rotary design allowing for great flexibility in field piping layout. Compact valve size. Valve position face plate is graduated on both sides and can be rotated allowing a choice of mounting position. Easily adaptable with ESBE electronic motor actuator series 60 or 90. Suitable fluid: water (maximum 0% glycol) Ordering: -Way Valve Code No. Connection Leakage in % of flow Cv* Size Type Mixing Diverting Body Reference 06B890 / MG B89 / MG B890 / Way MG B DZR Brass MG B MG B8969 -/ MG 2-8 Code No. Connection Cv* Leakage in % of flow Size Type Mixing Body Reference 06B898 / MG B8982 / MG B898 /4. 4MG B MG B Way Brass 4MG B8986 -/4 2 4MG B896 / MG B8990 Solder. 4MG B899 -/4 4 4MG 2-2 * Cv = Flow rate allowed by the valve in GPM with a pressure drop of one psi.

3 & 4-Way Mixing Valves Piping Arrangement: -Way Valves Ideal valves for mixing and diverting applications. Reduces risk of low temperature water returning to boiler. s Double mixing function, providing proportional mixing from to and to. Reduces risk of low temperature water returning to boiler. Mixing From To To Return from Diverting From Return from From To Return to Return to Faceplate: The valve position plate is graduated on both sides and can be adjusted to correspond to the installation. After the removal of two flat head screws, the cover plate can be installed to match the piping orientation Way Valve VDKIB22 Danfoss 0/08
