产品简介
Slurry Ball Valve
It has special design valve seat, matching hard sealing surface hardening treatment process, runner hardening treatment, double-blocking and venting function design, fire prevention and anti-static structure characteristics, high matching adaptability to working conditions, guarantee The device runs stably for a long period of time.
规格系列:NPS1/2"~48" CLASS150~2500
适用领域:The slurry ball valve is suitable for severe working conditions such as emergency cut-off, high-frequency switch, high temperature, high pressure difference, high wear, strong corrosion, multiphase media, alternating cold and heat, crystallization, etc. (such as ore pulp, concentrate slurry, tailings Pipeline transportation),






优势特点
Hardening of the sealing surface;
Full-through bore, Low flow resistance;
Anti-dust and anti-accumulation, long life ;
Flowway hardened,anti-scouring.
工作原理
The 90-degree angular stroke opens and closes, and the opening and closing is rapid; theFull-through bore has strong flow capacity; the special hardening process makes the sealing surface stable and reliable for a long time; the spring cavity dust-proof design extends the valve life and maintenance-free operation time.
