High-Performance Ductile Iron Gate Valve with Grooved Flange End

1, quick opening and closing, no friction, easy opening and closing, durable. 2, the channel is smooth, the flow resistance coefficient is small, it is not hindered by the flow direction of the medium, the structure is compact, and the weight is about 40% lighter than that of the flange type. 3. The valve plate is encapsulated with rubber as a whole, and the vulcanized valve plate can ensure accurate geometric dimensions, good interchangeability, not easy to fall off and elastic memory by adopting European rubber vulcanization technology.4. The valve stem and valve cover packing are designed with three O-ring sealing rings, which can reduce the friction resistance of the switch, reduce the water leakage and replace the sealing rings without stopping the flow of medium in the pipeline. area of application The Z85X-1 6Q fire-fighting groove concealed rod gate valve is used as a regulating and intercepting device in fluid pipelines such as tap water, sewage, buildings and fire-fighting systems.size inch22.1/23468101214161824262830323642mm5065801001502002503003504004506006507007508009001050A5163.576102152200248299327375419559603648737781876978C Travel6278961271702202703303504204706006506857808059301020H Closed4654805906868151052108712481595172019752375246625803070315032753850H1-----1430147017902115238026603270336035704230432045905250LBW /RF29233035643255960078783888999110921397144815491651177820832438LRTJ29533335943556266479184189299410951407146015621664179420992454V300300400400600-------------V1-----600800600600600600800800800800800800800Weight RF kg4451811362945097601035144017872430462051207420791491501040024100Weight BW kg36437211525543863592013101510216039204295498067107834822020230Overseas Exhibitions:/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
