DIN EN 13617-3:2012-05 EN 13617-3:2012 (E) 4 Introduction The function of the shear valve is to prevent continuous liquid or vapour release in the event of impact or fire DIN EN 13617-3:2012-05 EN 13617-3:2012 (E) 5 1 Scope This Eur
26、opean 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, b
27、oats 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. NO
