The EV Metal double block and bleed valve has been developed towards the demand for high flow and low pressure drop, to capitalize the significant investment in storage capacity related to hydrogen fueling facilities. In the hydrogen refueling facilities of the future, efforts to enable service without interrupting fueling will become crucial to the hydrogen customer. To allow for service without downtime on the facility, a clever pattern of double block and bleed units will enable to isolate areas and allow for service in these isolated areas. This could be inspection of storage/ replacement of safety valves, service on compressors, valve panels or dispensers. All in all; from the storage to the vehicle, several points of double block and bleed is required, not to disturb too large areas and thus prevent the customer from fueling. With the EV Metal double block and bleed valve, globe valves with close to nominal bores, minimizes the pressure drop between the storage and the vehicle, and maintains higher flowrate at minor pressure difference. This means better capitalization of the storage volume.
The EV Metal double block and bleed valve features:
•Large bore globe valve in the main flow means low pressure drop at high flow. •3/8’’ needle valve as bleed function. •1’’ and ¾’’ MP sockets •1050 Bar MAWP •Produced in accordance with 68/2014/EC and ASME B31.3 •All EN 1.4404 pressure enclosure for hydrogen compatibility. •Lock out/tag out on request (Not shown). •Inline main flow.
EV Metalværk has worked with production of fittings and valves for more than 30 years, and has achieved great competence within these fields. Thanks to our highly technological production equipment and experienced development department, we are further the preferred cooperation partner for unique solutions and production of special articles.
