Since corrosion resistance can be improved relatively inexpensively, it has also been used as countermeasures against metal ion elution in addition to measures against corrosive fluids and crevice corrosion.

When the fluids are ferrous metal corrosive, it is necessary to form a valve box with special alloys with superior corrosion resistance or resin etc. The special alloys with excellent corrosion resistance are generally expensive. On the other hand, plastic valves are inexpensive but may be inferior in strength.

By applying resin lining to the flow surface of the metal valve body in our lining products both rigidity and corrosion resistance are achieved.
We have wide selection of economical rubber linings, fluoropolymer lining inert to most chemical and glass, porcelain etc. which meet customers' requirements.
