Switch without wear and tear: the ball off the valve seat and then rotate, eliminating the friction with the seat, to solve the traditional ball valve, gate valve, plug valve seat wear problems. Single seat design: Static single-seat ball valve seat, to ensure two-way zero leakage, to avoid the double seat cavity pressure increases. Anti-wear hard sealing surface of the spool: spool sealing surface layer of hardfacing welding and polishing, to meet the very harsh media occasions, the sealing. Double Stem Guide Pins: Stem Guide Slot, Slide along Hard Guide Pins to Smoothly Control Stem Lift and Turn. Mechanical Wedge Tightness: The cam bevel at the lower end of the stem provides a mechanical wedging force to keep the plug and seat member in close contact. Top-loading design: After the system is pressure-relief, it can be checked and repaired online to simplify the maintenance. Internal leakage detection: The valve body is designed with special devices, online leakage detection valve. Low torque operation: Due to the frictionless sealing surface of the ball valve, the torque is small. In addition to the large size, the pinion can be used. Optimum flow characteristics: Full bore and standard bore have high Cv values, reducing drag losses along the line and minimizing wear problems. Self-cleaning: When the spool off the valve seat, the medium can flow along the sealing surface 360 ​​degrees, the impurities in the media rinse. Can be injected sealant: In operation can be maintained, the sealant injected through the grease injector, the valve will be completely controlled to prevent leakage. Long life: track ball valve can replace those who normally fail to seal ordinary ball valve, gate valve, globe valve, plug valve. Track ball valve unique features, can effectively reduce the device failure rate, greatly reducing the user's use and maintenance costs.
