Directly buried type welded ball valve by all welded body and carbon reinforced fluorine long gasket, can be in frequent operation, impurities and chemicals under the condition of long life. Fine grinding stainless steel ball can ensure that open and close freely for many years, reliable operation. Structure of floating ball, elastic cant guarantee seal compression on a sphere, even in the case of pressure is not stable, the valve can guarantee closely. The valve stem leakage protection structure with two 'o' type circle, freely to rotate the valve stem and seal tightly. Directly buried type welded ball valve features: no need to maintain, adjust and lubrication, easy to install, low in operating cost under long-term reliable operation. Stem could be longer, and easy to heat preservation. Operating handle can be removed, the reversing installation. The body does not contain heavy and unreliable castings. Install regulator, it is very convenient. City gas: gas output pipeline, trunk and the regional supply, etc. Central heating: large heating equipment output pipeline, trunk and feeder. Heat exchangers, piping and the opening and closing of each circuit. Steel mills: all kinds of fluid pipes, exhaust pipes, gas and heat supply pipeline, the fuel supply line. All kinds of industrial equipment: all kinds of pipes, all kinds of industrial gas and heat pipe heat treatment. Buried type welded ball valve material: 1) Body: carbon steel ST37. 0,A106 - B； 2) 20 steel : sphere: stainless steel 304 or 3163) Stem: 2 cr134) : stem seal: fluorine rubber 5) as : ball seal: RTFE ( PTFE＋C) Directly buried type welded ball valve standard features: 1) : size: DN15 - 6002). Pressure: PN16 - 403). Working temperature: - 29℃? ＋200℃4) : buried type welded ball valve to adapt to the medium: oil/gas, liquefied natural gas (LNG)/liquefied petroleum gas, petrochemical, steel mills, heating pipes, etc. 5) Directly buried type welded ball valve operating mode: handles, gear ( Vertical/horizontal) , electric buried type welded ball valve features: buried type welded ball valve, there won't be the phenomenon such as external leakage. Because the seat is made of carbide fluoro of seal ring and disc springs, so adaptable to changes in pressure and temperature, the annotation of pressure and temperature range will not produce any drainage and smooth. Sphere with advanced computer processing detector tracking detection, so the sphere of high machining accuracy. Because the body material as pipe material, won't appear uneven stress, also won't because of the earthquake and the vehicle through the ground deformation, occurs when pipe ageing resistance. Sealing ring ontology with 25% content of Carbon, Carbon) RPTFE material, guarantee completely without leakage, 0%) 。 Directly buried type welded ball valve can be directly buried underground, need not build high large valve well, only need to set up small shallow Wells on the ground, greatly reduce the construction cost and project time. Can be adjusted according to the requirements of the pipeline construction and design, the length of the body and the height of the valve stem. Sphere of machining accuracy is very precise and convenient operation, no harmful interference. Adopting advanced raw materials, to keep PN25 more pressure. Compared with similar industry of the same specification products, the body is small, and beautiful. The normal operation of the valve, use cases, the service life of over 15 years. Directly buried type welded ball valve product details: 1, advanced seat: seat ball valve manufacturing experience for many years and design, low friction coefficient, the operating torque is small. A variety of the seat material, wide adaptation. 2, the Industrial Valves stem fly structure: set up the steps, at the bottom of the valve stem bottoms stem from inside the body, prevent the valve stem. 3, anti-static function: between the ball and body or stem the Settings of the anti-static spring, will be generated switch movement process of electrostatic export. 4, fire-proof structure: advanced refractory design, after the fire, the leak designed to be flexible graphite packing or stainless steel clamp graphite, satisfies the requirement of refractory, comply with the provisions of the API6FA and API607. 5, handle, use flat head stem, and handle the connection is not misplaced, thus ensuring the switch state is consistent with the valve handle instructions. To prevent misoperation with valve switch, the switch is open, seated position set a lock hole, to ensure that the valve is in the right place. 6, fire-proof structure: advanced refractory design, after the fire, the leak sealing elements forming a metal to metal seal after burning, comply with the provisions of the API6FA and API607. Strict for refractory, sealers adopt flexible graphite packing and stainless steel clamp graphite gasket seal, ensure no leakage. ( Please specify when ordering: all type fire FB) 7, Industrial Valves adopts both at home and abroad the most advanced support plate structure, improve the service life of the valve, reducing valve operating torque. Greatly prolong the service life of the valve. More products information please visit pump valve network query:
