Ultra high purity gas products

Low-pressure diaphragm valves KD Series

KD Series

The KD Series includes compactly designed diaphragm valves. 
Realizing high Cv values, they support semiconductor high purity gases. These high-reliability valves combine high durability and high corrosion resistance.

Features

  • With minimized body vertical hole dimensions, excellent gas replacement characteristics are realized through smaller interior volume

  • Realizes high sealing, high durability, degassing performance, and corrosion resistance through a proprietary gas-contact part seal structure

  • High corrosion resistance through carefully selected diaphragm materials and minimized individual variation through proprietary molding methods

  • Particle performance optimized through a clean manufacturing environment and interior polishing

Low-pressure zero volume valves ZCD Series

ZCD Series

The ZCD Series includes diaphragm valves with minimized internal dead volume (*A part) and enhanced gas replacement characteristics.

Features

  • Dead volume from seat to main flow path is minimized at valve closing, realizing superb gas replacement characteristics Reduced by 86% from our 1/4" KD type

  • Forcible lift of the lift part diaphragm prevents vacuum closure and improves opening speed

  • Replaceable structure allows users to replace the seat assembly
