Evaporator pressure regulator type KVP opens on
a rise in pressure on the inlet side, i.e. when the
pressure in the evaporator exceeds the set value.
Type KVP regulates on inlet pressure only.
Pressure variations on the outlet side of the
regulator do not aff ect the degree of opening as
the valve is equipped with equalization bellows
(6).
The bellows have an eff ective area corresponding
to that of the valve seat neutralizing any aff ect to
the setting.
The regulator is also equipped with a damping
device (9) providing protection against
pulsations which can normally arise in a
refrigeration system.
The damping device helps to ensure long life
for the regulator without impairing regulation
accuracy.
