Three ball valve, mainly divided into three parts, the middle part of the body part of the ball in the valve body, a floating sphere, sealed PTFE seal, if excessive temperature will have with seal edge Ministry two parts can be made into a variety of connections, change the form of a ball valve, two ball more, and three ball valve installed different, can be divided into: 
 1, the three inner thread ball valve and connection for the internal thread form, thread for the RC, ZG, the NPT, the PT, G, pipe thread, this connection is one of the most widely used form of 
 Two, three Ball Valve connection for butt welding, welded, soldered directly to the steel pipes in this connection, the weld with a welding groove, but also a common connection 
 3, three clamp ball valve, connection clamp quickly mounted to put on a clamp and connectors with pipe connection valve may be applied in the Health-grade fluid pipeline occasions such as the pharmaceutical , chemical plants, beverage plants, etc., but the pharmaceutical, beverage plants, the best choice for Sanitary Ball Valves, outside polished, quality to meet the sanitary requirements 
 Three socket welding ball valve, this connection is a socket weld connection is steel pipe welded into the ball valve and ball connection 
 5, the three-flange ball valve, the connection flange, at both ends with flange, this flange ball valve but compared to flanged ball valves, or slightly more complicated, but the flange ball valve price should be cheaper, flanged ball valve, wide flange ball valve, relatively cheap 
 Three ball valve is a Full bore ball valve, flow, easy disassembly, so the large number of applications in industries such as chemical, mechanical and electrical, petrochemical, Qi with 
 The main specifications are: ND6 was, DN10, DN15, DN20, DN25, DN32, DN40, DN50 
 Material: WCB, 20 #, 201,301,304,316, CFM, CFM8 
 Pressure, PN1.6, 2.5,3.2,6.4, test pressure working pressure of 1.5 times the pressure test to ensure safety at work 
 Three ball valve can also be with the platform to form a three-platform ball valve, pneumatic devices, electrical devices can be installed on the platform, you can also handle locked, locked, to prevent misuse
