4 Way Valves Type G & F
The ESBE 4-way valves are designed
for use in commercial or residential
heating and cooling systems, to
control and distribute water or
non-corrosive liquids to different
zones.
The ESBE four-way valve features a
double mixing function. When hot
water from the boiler is mixed with
the return water, the temperature
of the returned water rises (higher
than can be achieved with a
3-Way valve), reducing the risk
of condensation and assuring a
longer life of the boiler.
The mixing proportions can
be adjusted manually, or
in automatically controlled
applications, by means of a control
motor. The scale is graduated on
both sides and can be turned,
allowing a choice of mounting
positions.
