Inkjet valves from Sinotech can now replace almost every inkjet valve found in today's large character Drop-on-Demand (DOD) inkjet printers. Until recently, almost all inkjet valves were made by one US company who had a monopoly on the sales of these valves. Inkjet valves could only be purchased through the original manufacturer of the ink jet printer and at very high cost. For some time now, Sinotech has been selling its valves to most printer manufacturers including Loveshaw (Little David), Marsh, Alphadot, Digital Design, ABM Marking, Videojet and many others from around the world.
Now Sinotech can provide the very same ink jet valves directly to the end user. Every valve goes through a very extensive testing process using actual ink to test each valve and to assure that the valves are fully exercised prior to installation into an ink jet system. Simply open up the print head, exchange ink jet valves, close the print head and resume printing.
Sinotech announces the introduction of it's Sifel line of ink jet valve models (Pat. Pending). Sifel is a new class of flouroelastomer that is highly resistant to alcohol- and MEK-based inks. In fact, Sifel is even resistant to gasoline, toluene, hexane, acetone, and MTBE. So far, no inks have proved too tough for the Sifel seal. Initial tests indicate that a valve with Sifel seals lasts at least 2X as long as a valve made with less exotic polymers such as silicones or EPDM.
A valve containing a Sifel seal is available as a replacement for most makes of ink jet printers including those made by Loveshaw (including Little David), Marsh/VideoJet (most models including Unicorn), Alphadot, Digital Design, Tomco, Print Jet, ABM Marking and others.
