Enolgas Valvole Motorizzate Valvole motorizzate Valvola di controllo a 6 vie QM

6 Way control valve

Typical applications are systems where you need to manage the changeover from heating to cooling, even during the same day and independently for each individual zone. The six-way zone valves allow status changes (90° and 180° stem positions) and also the simultaneous closing of the power supply from both sources (45° BYPASS stem position).

BY-PASS FUNCTION 45° 6-WAY VALVE

When using the six-way valve with combined heating/cooling (radiant ceilings, fan-coils, etc.), the fluid within the circuit would remain completely isolated when the valve is in the closed position (no heating or cooling). The pressure of the fluid enclosed within the circuit may therefore increase or decrease due to temperature variations caused by the ambient temperature. The six-way valve is equipped with integrated over pressure protection to compensate for such pressure variations. The upper ball of the valve has a special bypass design that maintains the connection of the “user” with the “source” even when the valve is closed (stem position 45°). The combined action of the two spheres (upper and lower) prevents fluid circulation when the valve is in the closed position. The overpressure protection system does not compromise the hydraulic separation between the two circuits, which always remain separate.

USES 

Typical applications are systems where you need to manage the changeover from heating to cooling, even during the same day and independently for each
individual zone. (Glycol max 50%). A single motorised six-way valve with actuator can replace four valves therefore replace two-way motorised zone valves, easily solving the complication of their synchronising the opening/closing of the two sources. The six-way zone valves allow status changes (90° and 180° stem positions) and also the simultaneous closing of the power supply from both sources (45° BYPASS stem position).

WORKING PRESSUREMax 16 bar
Differential 2 bar
TEMPERATURE LIMITSFrom -20°C to + 130°C.
NOTEAccording to UNI EN 13828 in presence of water which could be aggressive for brass alloy, as agree with UNI EN ISO 6509 standard, is necessary the DZR brass alloy. The manufacture is available on request.
