Hose End Valves

Offspring offers a range of valves for regulating fluid transfer between the hose string and tanker for both oil products and LNG.

Usually found on a floating hose, hose end valves are used for the On / Off operation of transference of fluid from the hose to the tanker, in addition to preventing water ingress whilst not in operation.

Offspring’s hose end valves’ lightweight yet robust construction reduces the impact on the buoyancy of the floating offloading hoses, as well as, ensuring they are able handle years of heavy lifts and service life mostly spent in water.
