Ball valves are generally the least expensive of any valve configuration and have low maintenance costs. In addition to quick, quarter turn on-off operation, ball valves are compact, require no lubrication, and give tight sealing with low torque.
The three-piece low-temperature socket welding ball valve belongs to the three-piece low-temperature ball valve series. The valve body is composed of three sections. The two ends are socket welding connection surfaces. After special low-temperature treatment, the temperature resistance is -50 degrees and the pressure resistance can reach 7.0. MPA.
Engineering pressure: 7.0MPA 1000WOG
Operating temperature: -50 degrees to 230 degrees

3PC ball valve socket-welding is to extend the pipe into the valve body for welding, the strength of welding seam, stress state is better than socket welding type.
Ball valves are generally the least expensive of any valve configuration and have low maintenance costs. In addition to quick, quarter turn on-off operation, ball valves are compact, require no lubrication, and give tight sealing with low torque.
Conventional ball valves have relatively poor throttling characteristics. In a throttling position, the partially exposed seat rapidly erodes because of the impingement of high velocity flow.
