Shut-off valve QDV15,148H3272-3273 Danfoss Drain valve

Shut-off valve QDV15,148H3272-3273 Danfoss Drain valve

QDV is a shut-off valve, designed particularly for
draining oil from systems containing refrigerant
(ammonia) under pressure.
The valve will close immediately on release of the
handle, thus protecting user and environment
against unne cessary refrigerant leaks. The valve
should as a rule be installed as illustrated in fig. 1.
In order to pre vent hydraulic pressure building
up between the stop valve and the QDV an
integral relief device is included as part of the
cone arrangement, which will open at approx. 16
bar (232 psig).
QDV is designed to meet the safety demands
specified by national and international
authorities within industrial refrigeration.

Applicable to R717 (ammonia).
