Air valves for heavy-duty flood prevention, oil booms and flexible storage tanks for water, oil and fuel.
The MV XGN is an updated version of our proven MV XG model. Featuring a smart new screw cap design optimised for safety and reliability, it is an ideal solution for oil booms of limited size, inflatable boats, tanks or other similar objects.
New screw cap design optimises safety and reliability
Same trusted build quality as standard MV XG model
Allows large air volumes to pass through quickly
Spring-loaded valve disc eases locking and release
Salt water and oil resistant
Easy handling characteristics
Practical reliability
The new screw caps’ softer, more rounded edges minimise the already small risk of ropes or other fastenings catching between it and screw nozzle. Furthermore, it also features a shorter attaching rope that further reduces the risk of catching or fastening. You can even use the same adaptor and mounting tools as the MV XG model – no problems, no frustration, just reliable performance when you need it.
As well as delivering easy handling and insertion in any weather conditions, the MV XG has two seals, is salt water and oil resistant and can be applied to any fabric material between 1 and 3 mm in thickness. The valve is made from tough Polyamide 6-6, Acetal copolymer and features a stainless steel spring and synthetic rubber seals.
