Product Structure Features
1, the valve body using casting structure.
2, the seat with O-ring seal and preload force applied to the floating valve seat structure, so that the two-way valve inlet and outlet seal; and the structure of the opening and closing torque only ordinary valve 1/2, to easily open, off valve.
3, the seat with PTFE seal on the surface, with PTFE pairs of metal and metal to metal seal, PTFE sealing surface at the same time remove the role of the dirt gate.
4, the valve gate, either fully open or fully closed with the sealing surface is always consistent with the sealing surface is protected from direct erosion of the media, thereby extending the service life.
5, the valve is fully open, the passage is smooth, the flow resistance coefficient is very small, no pressure loss, can pass the hair ball cleaning pipeline.
6, when the valve is closed, it can automatically remove the lumen high pressure (see working principle diagram), to ensure the safe use.
7, the use of closed gear rotation opening and closing instructions institutions, long-term clearly reflect the valve opening and closing situation.
8, Buried valve surface with epoxy coal tar preservative treatment, with the same life pipeline. One-piece flange stainless steel high temperature ball valve, flange stainless steel high temperature ball valve, stainless steel ball valve.
