Product features
The disc and shaft are connected without pin to reduce the leak achieve on-site replacement.
Ball-type sealing is adopted by the connection of Disc and Seat ensuring better connection of Disc and Seat, better sealing capacity and low torque. The double stem designof the Disc efficiently lowers the pressure loss of the valve and reduce flow resistance.
The seat has no skeleton and adopts concave and convex slot design. Seat stability, sealing compensation and effective reduction of torque. According to the requirements of different working conditions can have a variety of different material choice.
The shaft and body can be accurately connected to the plate and self-lubricated by adding a bushing design to extend the life of the valve.
According to the requirements of different working conditions (body, plate, shaft, seat) can be a variety of different materials to choose
The upper and lower shaft ends of the valve are designed for special sealing to ensure zero leakage of the outer seal of the shaft end.
Within the rated pressure range, the product torque is reasonable. It has been verified by practice that the sealing life of the product is long and the opening and closing torque is stable.
