fast valve
6.It is this resourceful and dynamic place of Yuhuan that bred and grew a now fast-expanding entrprise-Taizhou Zhenhua Valve Ltd.
7.On top of one of the fast-opening ends that closed to the pig receiver &launcher shall assemble vent valve, safety valve and pressure gauge, and at the bottom shall assemble drain valve, sideway inlet and vent valve to take out medium from the main pipe as the power of forcing pig and conveyance medium.
9.To against the difficulty in implementing fast run back (FCB) in large scaled fossil-fired power plants, with the coordinated pressure reduction strategy by using boiler pressure control valve (PCV) for drainage and bypass of turbine for dredge and integrated override control, set-point tracking, automatic transfer of control modes, etc. , the FCB function is successfully accomplished. The security of power grid and power plant is enhanced.
