Shanghai Rong Titanium Valve Manufacturing Co., Ltd. is a fully welded ball valve [lock] professional manufacturers. The quality of survival, integrity and development, with a collection of scientific research, design, manufacture, sales and service in one of the high-quality staff, strong technical force, advanced production technology. Sophisticated processing equipment, improve the detection equipment, a sound quality assurance system to ensure product quality and reliability. Fully welded ball valve standard features: 1 ☆: Diameter: DN15 ~ 1000 2 ☆: Pressure: PN 16 ~ 40 3 ☆: Working temperature: -29 ℃ ~ + 200 ℃ 4 ☆: gas pipeline welded ball valve adaptation medium: oil / gasoline, liquefied natural gas / liquefied petroleum gas, petrochemical, steel mills, heating pipes, etc. 5 ☆: gas pipeline welded ball valve Operation: Lever, gear (vertical / horizontal), electric, turbine fully welded ball valves Application: 1 ☆: City Gas: Gas export pipelines, trunk and each branch supply pipe. 2 ☆: Central Heating: large heating equipment export pipeline, the main trunk and feeder lines. 3 ☆: Heat exchangers: Pipeline and various open and close the loop. 4 ☆: steel plant: a variety of liquid pipelines, gas pipelines optional release, gas and heat supply pipelines, fuel supply pipe. 5 ☆: all kinds of industrial equipment, all kinds of heat pipes, all kinds of industrial gas and heat pipes. Locking fully welded ball valve fully welded ball valve Material: 1 ☆: Body: Carbon steel ST37.0, A106-B; 20 gauge steel 2 ☆: Sphere: Stainless steel 304 or 316 3 ☆: Stem: 2Cr13 4 ☆: Stem Seal: perfluorinated rubber 5 ☆: ball seal: RTFE (PTFE + C) fully welded ball valve performance: 1 ☆: no maintenance, adjustment and lubrication, easy to install, long-term reliable operation at low operating costs. Surface spray treatment technology, shiny appearance, in the country has been in the lead. There will be no external leakage and so on. Body is welded structure, light weight and easy to insulate the valve. Installation adjustment mechanism is very simple, the operating handle can be removed, change to the installation. 2 ☆: As the seat is made from carbon fiber-reinforced Teflon sealing ring and disc springs formed, so the changes in pressure and temperature adaptability, in marked pressure and temperature range will not produce any discharge slip. 3 ☆: Processing sphere detector with advanced computer tracking and detection, so the sphere of precision. 4 ☆: As the body material with the pipe material, it would not appear uneven stress, it will not go through because of the earthquake and ground vehicles and sometimes deformed, anti-aging pipelines. 5 ☆: Integral fully welded, Equal and adjustable channels with fixed and floating ball ball, double piston effect sealing system automatically inject sealant bearings. 6 ☆: To prevent static electricity between the stem and the ball and the stem and packing boxes are equipped with steel balls and spring, you can keep all the parts of the valve body conductive, so that the current through the area, discharge any static electricity. Not only to prevent fire, and to prevent corrosion, to achieve a temporary cut in order to timely maintenance. 7 ☆: stem anti-off function because of pressure on the valve stem by the total power generated from the stem so designed as anti-off structure. 8 ☆: thrust washer support with low friction material pressure to the valve stem so that the stem only play the role of transmitting torque.
