Application:
The two-way valve (a three-way valve may also be used) is installed in heating and cooling systems
with a closed water circuit (e.g. central heating systems, fan coil units, chilled ceilings or fan convectors)
and serves the flow volume and temperature control in combination with actuators and thermostats.
When used as a three-way valve, it is for mixing or distributing the volume flows in bivalent heating
systems or hot water storage cylinders, for instance in solar or heat pump installations.
Material:
Valve body made of Ductile Iron, disc and stem made of Stainless steel, Seal ring made of Teflon.
Function:
When used as a two-way valve, the SUNFLU two-/three-way valve has one inlet port (A) and one outlet
port (AB).
If the stem is pressed down, the straight port (AAB) is opened.
The central nipple is closed with a blind flange. The valve can be used as three-way valve after removal
of the blind flange.
When used as a three-way mixing valve, the valve has two inlet ports (A and B) and one outlet port
(AB).
Depending on the position of the valve disc, the cold and hot water is mixed. If the stem is pressed
down, the inlet port A is opened and the inlet port B is closed.
When used as a three-way diverting valve, the valve has one inlet port (AB) and two outlet ports (A and
B).
Depending on the position of the valve disc, the direction of flow is diverted from one to the other outlet
port.
