Series V46SA
Pressure Actuated “Low Flow”Water Regulating Valve
Introduction
The V46SA is a direct acting, “all range”,
pressure actuated modulating valve, used to
control the waterflow to a condenser by directly
sensing pressure changes in a non-corrosive
refrigerant circuit. The V46SA is specially
designed for use on equipment requiring a low
condenser waterflow such as icemakers, small
heatpumps and watercoolers.
The springhousing and power element are
rolled to the valve body.
Rubber diaphragms seal the water away from
the range spring and bellows part so these are
not submerged in water where they would be
subject to sedimentation and corrosion.
The valve can be ordered style 5 (without
capillary), style 13, style 34 and style 50 (incl.
75 cm capillary).
The capillary part will be delivered separated
from the valve.
