VP300 Poppet Valve

Engineered Solutions

The VP300 is a versatile pneumatic valve designed for dispensing materials with low to mid-high viscosity, such as silicone, RTV, epoxy, rubber adhesive, and grease. It features a diaphragm that separates the driving parts from the wetted parts, enhancing valve longevity and reducing maintenance needs. The valve operates by applying air pressure, which opens the valve seat to dispense material. The shot size can be adjusted using the control knob. The suck-back effect prevents material lumping by changing the volume in the material area when the valve closes.

Catalog excerpts

VP300Poppet Valve The VP300 is a multipurpose, poppet-type pneumatic valve 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. 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 suck-back effect occurs when the valve is closed because of the change in the volume of the material area as the poppet moves up in the valve Features • Suck-back effect • Suitable for filled materials • Seperated wetted parts • Fine tune shot size Models VP300 Poppet valve Sales & Support Fisnar Global Headquarters Tel: 1 (973) 646-5044 www.fisnar.com Material delivery pressure: 85 psi Flow rate: 2.4 l/min Max.
