VP300: Poppet valve

VP300 Pneumatic Poppet Dispensing Valve

The multipurpose VP300 Pneumatic Poppet Dispensing Valve is designed for dispensing low to mid-high viscosity materials, such as silicone, RTV, epoxy, rubber adhesive, grease, liquids containing filler, etc. A diaphragm located between driving parts and wetted parts increases the valve life and reduces valve maintenance.


3-Way & 4-Way Valve 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 VP300 valve has a suck-back effect that eliminates lumping at the end of the needle after dispensing.

The model DSP501N is a suitable controller for the VP300 valve. For faster actuation, the 4-way VC1195N valve controller is recommended.
