Features:
Top-mounted design: the main parts of the valve, such as ball and seat, can be mounted and dismounted from the top of the valve, which is convenient for online maintenance and replacement.
Fixed shaft support: the ball is supported by a fixed shaft, which keeps it stable during rotation and reduces friction and wear.
Superior sealing performance: metal-to-metal sealing structure is usually adopted, together with soft sealing materials (e.g. PTFE) to ensure sealing performance under various working conditions.
Flexible operation: it can be driven by manual, electric or pneumatic means to meet the needs of different occasions.
Main Technical Parameters
Nominal pressure: According to specific models and specifications, the nominal pressure range can vary from ANSI Class 150 to 2500.
Working temperature: usually can work in the range of -196 ℃ to 550 ℃, depending on the material and seal structure of the valve.
Connection method: common flange connection, butt-welding connection, etc., can be selected according to the needs of the piping system.
Driving mode: including manual, electric, pneumatic and other ways, can be selected according to the ease of operation and the degree of automation.
