When dispensing high viscosity materials, after stopping putting pressure onto the surface of liquid, the materials would be able to continue pouring out due to the remaining air pressure. As a result, it would lead to some problems regarding material consumption or not be able to control the quantity of dispensing fluid.
Our Suck-back valve would prevent tunneling and dripping effect. This helps you achieve consistent deposits and allows users to dispense virtually everything inside the syringe barrel reservoir — reducing fluid waste and operating costs.
FEATURES:
BV-303 is suck- off type
Most suitable for the process requiring the vacuum efficiency to prevent the remaining pressure after dispensing.
Applied materials of BV-303: Epoxy, Silicone, Urethane, Engine oil
