Shut-oﬀ valve Type QDV 15

Quick Closing Drain Valve designed particularly for draining oil from systems

QDV is a shut-o 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 g. 1.

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 specied 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 shut- o valve and QDV)

• Can be supplied together with a stop valve for quick on site mounting (g. 1)

• Max. operating pressure: 40 bar (580 psig)

• Temperature range: -50 °C – +150 °C (-58 °F – +302 °F)

• Classication: DNV, CRN, BV, EAC etc. To get an updated list of certication on the products please contact your local Danfoss Sales Company.

Refrigerants

Liquid refrigerant can be trapped between the stop valve and drain valve causing an unsafe, high-pressure situation, or potentially damaging either valve.

The internal relief device in the Danfoss QDV allows refrigerant to slowly bleed if internal valve pressure exceeds 16 bar (232 psig). Further, the valve is easily actuated by hand (without tools), and has an internal spring mechanism to instantly close the valve if the actuator is let go. All QDV valves are in angle orientation with FPT outlet, suitable for safe draining.

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Pressure and temperature data

QDV is a backpressure dependent valve. If any tube or hose is mounted on the outlet of the QDV it has to be calculated to prevent back pressure building up when relieving.

For further information please see installation guide for QDV. Flammable hydrocarbons are not recommended, for further information please contact your local Danfoss Sales Company.
