Mini Poppet Valve The VMP30H is a multipurpose, mini-poppet, pneumatic valve designed for dispensing low to mid-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 seals.
A diaphragm located between driving parts and wetted parts increases the valve life and reduces valve maintenance.
Operation
When air pressure is applied to the valve, the valve seat will open and the material will be dispensed. Shot sizes may be fine tuned by turning the control knob at the top of the valve.
The VMP30H valve has a "Suck-back effect", which draws material back into the fluid body at the end of the dispensing cycle. This eliminates lumping at the end of the needle after dispensing.
The model DSP501A is a suitable controller for the VMP30H valve. For faster actuation, the 4-way VC-1195A valve controller is recommended.
