Dumping valve is a high performance industry valve which made

by henan quanshun flow control science & technology

Co,ltd,which has characteristics of anti-abrasive,anti-high

pressure and anti-scrab . Dumping valve is widely used in alumnia

,coal chemical,steel ,metallurgy indusrty for dischaging materials

in the reaction kettle or reactor.
1.valve body design
The series of dumping valve has two constructions :Y type and

angle type .According to the actual operating conditions, has two

types: pipe connecting and flat bottom. We can design the

dumping valve according to customer’s demand.
2.Special plated
An anti-washing and anti- corrosion protection plate is set in the

cavity of the valve body.At the moment of the valve opened,the

plate can protect valve from washing and cossosion,and carry

out chemical Ni/P plating treatment on the whole valve which

makes the surface hardness up to HRC60.
3.Sealing surface
The sealing adpots spherical seal ,the surface of which is line

connecting. This can ensure the sealing realiability and avoid

scarred .Moreover ,the valve belt has back sealing structure

which can protect packing in full-open state.
4.Rotation-resisent device
A rotation-resisent device is set up to ensure that the valve stem only has straight line motions ,and no more revolving motions.
5.A variety of driving methord can be choosed
The driving manner of the valve include hand driving ,electric driving ,pneumatic and gear driving .
