Top entry eccentric half ball Valve features
1.Pressure loss: full -time water loss is zero, flow completely smooth, medium body will not be deposited in the cavity.
2.Easy maintenance: valve repair without removing the road from the tube, simply open the valve cover can be repaired.
3.Long life: no wearing parts , as eccentric, open and close the valve when the friction between the sealing surface ,then the long service life.
4.Suitable for high-velocity medium : direct flow, strong eccentric-crank to fit the high velocity and no vibration.
5. Granule abrasion resistance: V-shaped opening of the spherical cap and the shear effect between the metal valve seat, in the closing process, only the crown at the last moment before their eyes the ball valve seat, not the formation of friction and resistant seat grinding of nickel alloys, can not easily be washed and wear, which applies to contain fiber, small solid particles, pulp, etc.
6. All points on sealing sphere various revolving radius, eccentric sphere curve are being progressively increasing curves in closing valve, after sealing sphere enter into seat, close and tight forms enough sealing pressure ratio to realize more steady and reliable dual direction sealing performance
7. Widely used in water ,sewage, solid particles containing micro, water, steam, gas, natural gas, oil and so on .
