Poppet Valves for Precision Dispensing

A multipurpose poppet valve developed for dispensing silicone, grease, RTV, single part epoxy, and fluid with fillers. A diaphragm located between the driving parts and the wetted parts increases the valve life and reduces valve maintenance. The valve design also provides a suck-back effect which prevents post-dispense "dripping."

A mini poppet valve designed for smaller shot sizes than the VP300 dispensing valve, although the cycle rate is the same at 300 cycles a minute. Suitable for dispensing high viscosity liquids such as sealants, silicone, RTV, epoxy, adhesive, grease, and filled materials. The VMP30H contains a diaphragm to increase the life of the valve and reduce maintenance costs.

When using the DSP501LF controller to operate a poppet valve, the internal return spring is used to close the valve at the end of the dispense cycle. For faster cycling and an increase in suck-back, the VC-1195A is recommended, which provides an air pulse to open the valve and a second air pulse to snap the spool shut.
