Structural characteristics and uses

1.little pressure loss:warer loss is zero at full open ,compeletly smooth flow.which will not be deposited on dielectric Valve cavity.

2.Bears the particles attrition:V shape opens the mouth between the crow and the metal valve seat the action is shear,in the closure process.only then depends on is last the moment ball crown to the valve seat.does not form the firction,also the valve seat makes whit the wear-resisting nickel alloy,si not easily washed out the attrition,thud is suitable to contains the textile fiber,the small soild particle,the thick liquid and so on.

3.Suitable for high-veocity media：direct flow,soild eccentric crank make it suitable for high speed without vibration.

4.Long life:no vulnerable parts,there is on friction between the surface when the valve opens and close due to the function of the eccentric,therefore there is long life.

5.Easy maintenance:valve repair without remove from the pipeline,as long as the valve cover is opened foe maintenance.

6.Widely used in water,sewage,containing tiny solid particlaes,water,steam,gas ,gas,

Oil.ect.
