Shanghai Shanghai Fluid Equipment Co., Ltd. is a long time to get in Shanghai, "the contract, the word" gold units. Quality first, sincerity and credibility based on the market, the customer first, harmony and win-win for the purposes set up factories to make unremitting efforts, doubling the struggle to provide newer and better products and services to new and existing customers, creating value for customers. Welding Ball: very widely used in recent years in various fields, and its superior quality, high-performance stability, life is ordinary steel ball can not be achieved. Widely used in city gas, urban heating, petrochemicals, shipbuilding, steel, regulator stations, power plants and other types of plumbing. Advantages: can be buried in the ground, do not build tall valve well reduce the project cost, but also to avoid causing harm personnel welded ball valve can be used for long-term reliable operation of the valve operation, in the case of normal operational use of the valve, the warranty period of 20 years . Welded ball valve Features 1, connection: welding and flanges. 2. Transmission: The handle, turbines, pneumatic, electric and other transmission structure, flexible and light switch. 2, the valve seat by a PTFE (high temperature, wear) seal rings and springs changes in pressure and temperature adaptability within the operating range without any leakage. 3, stem anti-leakage structure, the bottom of the stem has a PTFE seal the puncture and an O-ring, there are two O-ring above, consisting of two PTFE gasket to ensure no leakage. 4, the body is light and easy to heat. 5, the buried ball directly buried, do not build tall valve well, just set up a small shallow wells on the ground, saving construction costs and engineering time. 6, the valve can be adjusted according to the length and stem height pipeline construction and design requirements. 7, sphere very precise precision easy operation, no adverse interference. 8-piece welded body structure, there will be no external leakage. 1. This welded ball valve structure made of carbon steel seamless pipe pressing integral welded ball valve. 2. The valve stem AISI303 stainless steel, valve body AISI304 stainless steel with finishing grinding production, with excellent sealing performance and corrosion resistance. 3. The use of carbon reinforced PTFE sealing ring vacuum ramp elasticity in the sphere, so that sealed to zero leakage, long life and other advantages. 4. The valve structure is compact, light weight, easy to heat, easy to install. This valve is usually installed horizontally. 5. The one-piece welded ball valve absorb foreign advanced technology, combined with the actual situation developed, with domestic instead of imported, fill the gaps. Widely used in the field of long-distance natural gas pipeline, oil, heat, chemical and thermoelectric pipe network. Welded ball valve installation: When and pipe welding, the valve should be at 100% full open position, so as not to damage the valve ball welding slag splashing, while ensuring that the internal valve seal temperature up to 140 degrees Celsius, cooling can take appropriate measures when necessary.
