Detailed Introduction

Structural characteristics and uses

1、Pressure loss:full-time water loss is zero,flow completely smooth,medium body will not be deposited in the cavity.

2、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,cannot easily be washed and wear,which applies to Contain fiber,small solid particles,pulp,etc.

3、Suitable for high-velocity medium:direct flow,strong eccentric-crank to fit the high velocity and no vibration.

4、Long life:no wearing parts,as eccentric,open and close the valve when the friction between the sealing surface,then the long service life.

5、Easy maintenance:valve repair without removing the road from the tube,simply open the valve cover can be repaired.

6、Widely used in water,sewage,solid particles containing micro-,water,steam,gas, natural gas,oil and so on.
