The VMP30H is a multipurpose, mini-poppet pneumatic valve designed for controlled dispensing of low to high viscosity materials, such as silicones, RTV, epoxy, rubber adhesives, greases, and filled materials. The poppet design minimizes surface area and friction between the valve piston and the material, making it ideal for filled materials and extending the life of the valve. A diaphragm located between the driving parts and the wetted parts also increases the valve life and reduces valve maintenance. Shot sizes may be fine tuned by turning the control knob at the top of the valve. The VMP30H valve features a “Suck-back effect,” which draws material back into the fluid body at the end of the dispensing cycle.
