Design Features

First eccentricity: the center of the stem rotation deviates from the centerline of the seat to ensure a tight seal between the seat and the disc

Second eccentricity: the center of the stem rotation deviates from the center of valve body. When the valve is opened, the disc can be quickly separated from the sealing surface.

Third eccentricity: the center of the sealing ring cone deviates from the center line of the valve, completely eliminating the friction between disc and seat.

1. The yoke is designed according to ISO5211, which is convenient for installing gearbox, pneumatic or electric actuator.

2, Anti-valve stem blowout design

3, low leakage packing (optional), advanced metal-bonded graphite packing (for the bottom and top ) and low leakage packing (for the middle) to ensure a maximum leakage no less than 20ppm

4, Extend the bearing design, the use of long precision bearings, reduce valve stem friction, to ensure low operating torque, graphite ring is used to prevent pollutants from entering the bearing

5, Multi-layer seal design, elastic deformation of the seal ring can guarantee zero leakage, the seal ring is truly interchangeable, convenient maintenance

6, The valve seat surfacing hard alloy, the overall hardened valve seat, extending the life of the valve, reducing the number of maintenance

Design: API609

Structure: lug type, wafer type, double flange type, butt welding type
