Danfoss Shut-off Valve - Type QDV 15
Quick Closing Drain Valve designed particularly for draining oil from systems
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 unnecessary refrigerant leaks. The valve should as a rule be installed as illustrated in fig. 1. (in the Danfoss Data Sheet)
In order to prevent 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.
Features:
- Applicable to R717 (ammonia)
- Meets the safety demands within industrial refrigeration
- Handle can be positioned 360°
- Built-in integral relief device opening when 16 bar (232 psig) is exceeded. (preventing hydraulic pressure building up between shutoff valve and QDV)
- Can be supplied together with a stop valve for quick on site mounting (fig. 1)
- Max. operating pressure: 40 bar (580 psig)
- Temperature range: -50 °C – +150 °C
