Shipping

GN 880 oil drain valves may be used for draining non-pressurised oil, and under certain conditions. also for vacuum drainage.
The flow volume (l/min.) depends on the viscosity of the medium, the filling quantity and the temperature. Guidance values available upon request.
Other features are:
- easy and safe handling
- optimum flow rate
- high pressure resistance (up to 100 bar)
- high temperature resistance (-22° F to 320° F / -30° C to +160° C)
- 100% leak tightness tested
Other benefits of GN 880 drain valves:
- No risk of burns caused by hot oil
- No mess caused by uncontrolled oil drainage
- Quick and easy to use

See our Technical Section for pipe thread size details.
 
 

How to Use
After removing the protective cap (which is secured against loss with the chain), screw into the matching GN 880.1 connector piece.
When the connector is screwed in, the valve plate will open and the oil will empty through the hose into a pan.
Take off the connector after the oil has drained. The valve plate will be lowered and will close off the drainage outlet.
The container with the oil drain valve is ready for filling again.
