a. Max. air pressure 1Mpa
b. The valve works by plane fitting which will be no liquid fluctuation during whole process, which effectively avoid the liquid dripping and backflow at the exit when proceeding accurate micro sampling.
c. The valve was endowed with status output function at the moment of working and stopping, which is much easier for upper monitor to check the ON-OFF status.

(1) Specification: two/three/four channel valve
(2) Two way valve: The path from IN to OUT was opened or closed by rotor.
(3) Three way valve: C refers to public channel, path from ON to C is normally open, path from OFF to C is normally close.
(4) Action: when external trigger signal receives voltage DC7-33V, normally close path will be opened while normally open path will be closed.
(5) Channel diameter is 1.5mm which allows particles with diameter less than 0.1mm. When channel blocked, it will get through with liquid clashing the channel inversely. (except for dead blocked)
(6) Valve screw 1/4-28UNF (Adapted with Teflon hard tube and inverted cone joint)
(7) Max. air pressure ≤1pma
(8) Max. water pressure≤1.2mpa
(9) The valve core is made of particular fine ceramic or sapphire with reliable chemical and physical properties.
(10) The largest diameter of the particles through the path must be less than 0.1mm, kindly suggest filtrating equipment for small floating particles to prolong the product service life.
