Valve body materials: cast iron, ductile iron, carbon steel,stainless steel, copper and special alloy (cast iron, ductile iron, carbon steel surface resin spraying)

Choose different sealing materials according to different working conditions (e.g. NBR,EPDM,SIL,FKM,PTFE, food grade, seawater special rubber, stainless steel, special alloy, etc.)

Products are suitable for extremely viscous corrosive, wear resistant liquid, slurry or dry material, mineral treatment, sewage, fiber slurry and other working conditions

Can be used in medicine, food, chemical and other industries.

if you have special technical needs, please consult the company.


Product features

Integrated casting body with a variety of types of seats, products are divided into one-way seal, two-way seal, soft seat, hard seat can meet the requirements of various working conditions.

Ultra-short structure length, compact structure, small space occupation, can greatly reduce the overall weight of the pipeline system.

Strong and corrosion-resistant stainless steel gate ensures long-term sealing and prolongs service life.

Various packing types, suitable for all kinds of harsh and harsh working conditions, reliable performance, durability.

Lift gate sealing surface, can scrape the adhesive things on the sealing surface, automatically clean up sundries.

Choose hard seal stainless steel seal seat, plus hardened treatment (or thickening) valve plate, can better expand the use of temperature and pressure valve range.
