Overview / Design Principle:

These isolation valves offer 2-way Normally Open (NO) and Closed (NC), or 3-way Directional Control operation. while sharing similar configurations with the KM Series, the KL Series features larger orifice sizes with greater Cv values. Their design ensures that the only wetted parts are the valve diaphragm and body.

Fluid Control Applications:

Liquid Chromatography
Gas Analyzers
Analytical Chemistry
Water Quality

Corrosive Materials

Acids
Bases
