Space of the valve cavity employs streamlined design, overcoming turbulent flow of the media.

The spherical structure at the front part of the discs and bevelled sealed surface reduce impacts on media and also the flow -resistant coefficient.

The inner guide vane adopts a style of thin eggshell so as to ensure the flow of the media unblocked. At the same time, the weight of the valve reduces as well.

A largest flowing sectional area is created by reasonably lifting the height and enlarging the inner space, which also effectively avoid the produce of an air-chamber, upgrade the valve’s Cv value and overcome noise.

Excellent anti-corrosion

Internal and external surfaces of the valve body, bonnet, disc and the guide vane are all coated with epoxy resin without any exposure of iron.

Reliable sanitation

The epoxy resin and rubber used comply with sanitary standard DVGW

Inner components including the spring, the discs are all made of stainless steel.

Applying area

The two kinds of valves are widely used in heating systems and industrial water supply and drainage systems.
