In order to reduce the risk of offshore operations and improve durability, manifold of the boarding ladder itself is made of monolithic zinc nickel alloy to reduce the strength of seawater corrosion.
The manifold block uses a customized bridge check valve to match the directional valve with positioning. It makes the main ladder up, down and the extension and contraction functions of the front ladder at any time to achieve the random switch of the contradictory functions of pressure holding and floating. It can truly achieve the personalized needs of “going with the tide”. At the same time, in order to reduce the impact of the landing of the boarding ladder and the expansion of the inner arm and the outer wall of the oil transmission, the manifold is also equipped with the anti-impact modular valve, which is favored by the majority of users.
