HEROSE supplies LNG butterfly valves for shipbuilding
Butt welded butterfly valve type 17800
HEROSE is expanding its product portfolio of valves for cryogenic liquefied natural gas (LNG) with butterfly valves from Quadax and is taking over the exclusive distribution of the butterfly valves for the entire ship-side LNG Fuel Gas Supply System (FGSS).
HEROSE already has a comprehensive product portfolio of certified valves for cryogenic liquefied gases in the nominal size range up to DN200. With the addition of the butterfly valve, HEROSE is positioning itself even more broadly for the worldwide shipbuilding industry: The butterfly valve type 17800 is now available as a butt welded and top entry version up to DN400 in the nominal pressure of PN10, PN16 and PN25.
Butterfly valves for LNG ships
HEROSE supplies the butterfly valve Type 17800 exclusively for the entire ship's Fuel Gas Supply System (FGSS) with LNG storage tanks, bunkering manifolds, cold box units up to the engine or gas turbine in the temperature range down to -196°C.
The special feature of this butterfly valve is its four offset design. In contrast to the conventional sealing geometry of triple offset butterfly valves, the type 17800 is characterised by a symmetrical sealing geometry. A bubble-free 100% seal is achieved even under extreme temperature requirements. Further advantages of the butterfly valve are high flow rates (Cv values) for smaller nominal sizes, a uniform wall thickness, frictionless operation for a long service life as well as lower operating forces for smaller actuators.
The butterfly valve is available as a manually operated and an actuated butt welded version with short body as well as a top entry version. For maritime environments only the V4A (316L) is offered.
The high-quality butterfly valves from Müller Quadax are manufactured 100% in Germany on modern, fully equipped 5-axis machining centers and are released by HEROSE for each delivery with a separate quality inspection for the customer.
Strategic partnership for butterfly valves "Made in Germany"
The LNG butterfly valves are supplied in exclusive partnership with the family-owned company Müller Quadax in the LNG marine sector for drive technology in shipbuilding. HEROSE is thus expanding its comprehensive range of shut-off, non-return, control and actuator valves, gate valves, ball valves, strainers and safety valves.
