FIELD: oil and gas production.
SUBSTANCE: underwater valve assembly comprises valve, feed line 10 to be connected to remote fluid source 2 and to inlet 13 of valve 12. Valve outlet 14 is to be connected to discharge fluid line 15. Said assembly includes also tight casing surrounding, at lest, partially said valve. Fluid feed line 10 comprises outlet 101 inside said casing to set pressure there inside equal, in fact, to valve inlet pressure created by incoming fluid. Invention covers also the method of protection of said underwater valve.
EFFECT: possibility to use standard valves in deep waters.
