Design characteristics of Parallel Single Disc Gate Valve Intensively structured stem nut and lubricator make operation easy and flexible. Valve is fully enclosed for good protection and allweather service.. There is packing spacer ring in packing, and it can be injected with sealing grease to ensure the dependable seal and lubrication of valve stem.. Seal seat is double sleeve sealed for dual seal. Soft sealing surface uses PTFE to clear away sand grain and dirt, thus to ensure dependable seal. Middle flange uses metal waveform gasket to ensure dependable seal.. For valve carrying diversion hole, no matter whether it is fully opened or fully closed, disc and seat are always in contact, so that sealing surface cannot be eroded directly by medium, thus to lengthen its service life.. The structure of floating seat allows the double seal of valve inlet and outlet.. When valve is fully opened, passage is a straight pipeline, with little fluid resistance and pressure loss to allow hair bulb to clean the pipeline. Valve body can be cast or forged. Short flat gate valve without diversion hole uses welded structure for short length and light weight..

Flow Charalteristic The flow characteristic of flat gate valves with a diversion hole is equal to that of pipelines of the same specification.the characteristic is shown in per centum form..as for valves without a diversion hole,its cavity fly span is smaller than that of wedge gate valves and it is a regular cylindrical object,therefore,characteristics of the valves are similar except that they have a larger pressure lose. Besides,their flux adjustment behavior is better than that or the ones with a diversion hole.. 95% 5% 75% CV percent 5% 55% 5% 5% A B % 5% 5% 0% 0% 0% 0% % 0% 70% 0% % %Opening Ordinary Type Adiversion hole Type Valve opening CV characteristic graph DNCV Graph of Flat Valves With a Diversion Hole 0 000 0 000 0 0 Cv 000 7 00 Cv 00000 70 00 00 0000 0 5 0 00 000 0
