1, ball core adopts the design of round hole for high flow capacity, the characteristics of small resistance;
2, ball core is the use of special processing technology and surface hardening treatment (or do lining fluorine handling), its smooth surface corrosion resistance, long service life;
3, the valve stem with self-lubricating materials, effective transfer sealing force, small friction coefficient, the valve torque is small, high mechanical stability, sensitivity, valve to reduce response time;
4, ball valve has simple structure, convenient maintenance.
