Notfall-Absperrventil

Emergency shut off valveis designed to be installed in the places, e.g. that for refueling, which are exposed to collision or fire and required to be able to switch off the medium automatically in case of emergencies. The upper body shut off valve will switch off the fuel route automatically once the refueling machine is overturned by collision, so as to avoid the hazards. The single valve is deigned to shut off supplied oil flowing out, while the dual valve is designed to not only shut off the supplier oil flowing out but also prevent fuel from overflowing out of pipeline within the refueling machine. Materials: Main body: cast iron Sealing: Connecting thread: BSP 11/2” / NPT 11/2” Flow rate: 0-120 L/Min Working pressure: 0.2 Mpa Valve closing speed: 0.5 S Min. shut off temperature: 75°C Medium: gasoline, diesel oil, kerosene Utilization environment: -30°C - +55°C Characteristics: 1. Low profile upper-body: the design of internal thread and combined upper body dual valve allows single valve to be upgraded to dual valve without changing prior pipeline systems. 2. Multi-configuration options: the single valve pattern can be equipped with various thread sizes according to requirements. (“U” shape bracket can be provided if necessary) 3. 100% factory inspection.
