Product Function
(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) 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)
(5) Valve screw 1/4-28UNF (Adapted with Teflon hard tube and inverted cone joint)
(6) The valve core is made of particular fine ceramic or sapphire with reliable chemical and physical properties.
(7) When external trigger signal receives voltage DC7-33V, normally close path will be opened while normally open path will be closed.
(8) 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.


Three way valve:
Power on with DC24v (+/-), at this moment, when no powered with 7-33v between V-Tin and GND then OFF-C path will be opened while ON-C path will be closed; when 7-33v controller signal removed then three way valve will be back to boot default state, that is ON-C path opened, OFF-C closed.
Note: The trigger voltage must be less than 33V, or the inside circuit will be burned; and trigger voltage must be higher than 7v, or the control will not be reliable.
