⚠ Warnings
*
1. Conditionswhen fluid medium is liquid or chemical.
1. Surge pressure must be controlled lower than maximum operating pressure
when using with water and other liquids.
2. The specification above may not be applied, depending on chemicals or
mixed gases used as fluid medium. Make sure to use PISCO products after
verifying their suitability on the user side.
3. Liquid and chemicals are limited to those with no effect to valve material.
*2. Valve maximum operable pressure varies upon operating temperature. Please
refer to the "Relation of Operating Temp. & Max. Operating Pressure" graph
when use and operate in the condition.
