The top entry ball valve is designed with the double blocking and bleeding function and high-strength integral ball structure. It ensures that the positioning stem of the ball adopts two groups of O-rings with blow out proof structure, plus the fireproof packing structure on the valve stem. It can effectively prevent leakage and corrosion. The bearing with low friction coefficient moves the Nylon sealed metal seat towards the ball due to the nickel corrugated spring. The standard Nylon and PEEK valve seats with excellent two-way sealing functions at the inlet and outlet ensure the design of the effective sealing sealant housing device under the low pressure state, and the sealing sealant can be housing under the emergency state. The unique seat retractable technology is adopted for sealing the valve rod or valve seat.

Product advantage: top entry, online maintenance can be realized.
