Nearly 30 years of conical valve production has made us an expert in dealing with abrasive slurry in corrosive environment. Knowing the application details such as miller number, corrosion, expected valve life etc. we carefully select material grade, either wear resistant iron or low alloy steel with high or medium hardenability. Given the lifespan of the product, our material-heat treatment specialists gives suggestion on surface hardening process so does the right type of valve rings advised by rubber engineer.


The followings are examples of successful cooperation with original pump manufacturer:
