High Purity Gas Valve KD, Diaphragm Valve Straight Type, Manual (Part Numbers)

[Features]
· The KD series is a direct diaphragm valve with a compact design that provides high CV value. It is suitable for high purity gas for semiconductors, demonstrating high durability, corrosion resistance, and reliability.
· Superior gas replacement performance is achieved by minimizing the dimensions of the vertical hole in the body and achieving an internal volume of 1.2 cm3 (when 1/4" CVC male is open).
· The unique gas seal structure was implemented for better seal performance, high durability, outgassing performance, and corrosion resistance.
· The unique formation method and the high corrosion resistance of the carefully selected diaphragm material means there is little individual difference between pieces, and this gives high durability.
· The high-level production environment and inner surface polishing process delivers quality particle performance which supports high purity gas for the semiconductor industry.
