用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。本产品可广泛应用于造纸、石化、化工、冶金、电力、环保、石油、轻工等工业部门的自动化控制系统中。

产品特征：
■ 采用全通径或缩径设计，流通阻力小。
■ 阀杆采用内装式，轴肩及聚四氟乙烯（或增强石墨）推力垫结构防止阀杆因管道内压力而吹出，同时聚四氟乙烯（或增强石墨）材料减小阀门的启闭扭矩，使操作更为省力。
■ 耐火结构双重保护，当万一发生火灾而使密封圈烧损时，球阀的各个密封部位均能形成金属对金属的硬密封结构。

, Used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. This product can be widely used in papermaking, automation of petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial sectors in the control system.
Product features:
■ using full size or reducing design, small flow resistance.
■ stem with built-in, shoulder and polytetrafluoroethylene (or reinforced graphite) thrust pad structure to prevent the stem for pipeline pressure blow out, at the same time, polytetrafluoroethylene (or reinforced graphite) materials reduce the opening and closing torque of the valve, the operation is more labor-saving.
■ refractory structure of double protection, in case of a fire and the sealing ring is damaged, the ball all the sealing parts are able to form a hard seal structure of metal on metal.
Technical parameters:
■ nominal size: NPS1/2 ~ NPS8, DN15 ~ DN200
■ nominal pressure: Class 150 ～ Class 600 PN1.0 ~ PN10.0MPa
■ design standard: ANSI API 6D GB/T 12237
■. Structural length: ASME B16.10 GB/T 12221
Application: temperature ≤ 550 ℃.
■ flange end / butt-welding ends: customer requirements.
