EVS-EN 13617-3:2012

This European Standard specifies safety and environmental requirements for the construction and performance of shear valves to be fitted to metering pumps, dispensers, and/or satellite delivery systems installed at petrol filling stations and used to dispense liquid fuels into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l min-1. The requirements apply to shear valves at ambient temperatures from –20 °C to +40 °C with the possibility for an extended temperature range. It pays particular attention to mechanical and hydraulic characteristics.
