Suck-back valve BV-315

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.
