Receiver pressure regulator
Type KVD

KVD used to maintain constant and adequately
high condensing and receiver pressure in plant

KVD is a modulating receiver pressure
regulator. It opens on falling receiver pressure
and bypasses hot gas to maintain the receiver
pressure at the regulator setting (adjustable).

KVD and KVR form a regulating system, used to
maintain constant and adequately high
condensing and receiver pressure in plant with
heat-recovery, and in refrigeration and air
conditioning plant with air-cooled condensers.

Features

• Accurate, adjustable pressure regulation

• Wide capacity and operating range

• Pulsation damping design

• Stainless steel bellows

• Compact angle design for easy installation in
any position

• “Hermetic” brazed construction

⁄4 in. Schrader valve for pressure testing

• Available with are and ODF solder
connections

• Can be used as a relief valve from high
pressure to suction side

• May be used in the following EX range:

Receiver pressure regulator, Type KVD

Functions

Figure 1: Function for KVD

The receiver pressure regulator KVD opens at a fall in pressure on the outlet side, i.e. when the pressure in the
receiver falls below the set value.

KVD regulates only in dependence on the outlet pressure. Pressure variations on the inlet side of the regulator do
not

aect the degree of opening since KVD is equipped with an equalization bellows (6). This bellows has an

eective area corresponding to that of the valve seat.

The KVD regulator is also equipped with an eective damping device (9) against pulsations which can normally arise
in a refrigeration plant. The damping device helps to ensure long life for the regulator without impairing regulation
accuracy.
