API 6D/607 Carbon Steeel Cat Iron Stainless Steel Manual Gate Valve with Flange

Product Description:The gate of a gate valve moves linearly with the valve stem, usually with trapezoidal threads on the lifting rod. Through the nut at the top of the valve and the guide groove on the valve body, the rotary motion is changed into linear motion, that is, the operating torque is changed into the operating thrust. When the gate valve is closed, the sealing surface can be sealed only by medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by medium pressure to ensure the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate is forced to press against the valve seat by external force to ensure the tightness of the sealing surface.size inch22.1/2346810121416182022242628303236404248mm506580100150200250300350400450500550600650700750800900100010501200A5163.57610215220325430533738843848954059164169973778187697810291168C Travel657690125150208276351367418454510560610650740760820915101010501220H Closed4014344455567039211065117413301445163018302036213022852635259229403300351038204064H1----------230025502910301031653465361039504330483049755505LBW2162412833054024194575025726106607118138138649149149651016116813971270LRF178190203229267292330356381406432457508508559610610660711813813864V250300300300400500600600800800------------V1----------600600600800800800800800800800800800Weight RF kg263438,755951642373433524506717901040115015092084241327873380488053027520Weight BW kg233034488913424133133344567577611101085114201838226124503310484052757050Product photos:BVMC'S HISTORY:Package & shipping:Overseas 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
