Adhesive Dispensing Equipment


Meter, Mix & Dispense Valves


Micro-Metering Valve (MMV)

MMV is used for accurate shot metering during small parts assembly and encapsulation.

Features and Benefits

  • Positive displacement design provides high accuracy and repeatability, regardless of viscosity and fluid inlet pressure variations.
  • Threaded stoke limiter on the back of the air cylinder makes shot size easily adjustable
  • Simple, all-pneumatic operation
  • Minimal retained volume in dispense chamber assures fluid inventory exchange.

Typical Applications

  • Apply beads and drops for assembly applications
  • Electrical potting and encapsulation

More Valves to Choose From...


Double acting valve designed for dispensing adhesives with low to medium viscosity
 
Snuff-back extruder valve for extruding sealer, anti-flutter mastic. The nozzle and seat are all metal construction for long life dispensing low abrasive materials.
 
Manual flow valve is hand operated with a light trigger force. Provides precise control of low viscosity sealant and adhesive materials. Ideal for PVC sealers with glass or plastic fillers, low to high abrasive fluids, waterborne and solvent borne materials as well as most materials to 15,000 cps.
 
Air operated single-acting valve has an adjustable stroke piston which will repeatedly displace from 0.2cc to 4.0cc material. Used for accurately dispensing metered amounts of material on a repetitive basis.
 
Diaphragm valve designed for low to high viscosity materials in a wide range of shot sizes. Stainless steel construction ensures broad material compatibility. Unit has no-drip shutoff and operates up to 1,000 psi material pressure.
 
A spool valve with balanced spool design creates a fast "ON/OFF" function that is not affected by material inlet pressure up to 2,500 psi. The valve is suitable for materials with viscosities from 100 cps to 3,000,000. Includes snuff-back.
 
A rotary, micro valve is a self-contained valve capable of depositing small, accurate shots to 0.010 inch diameter at rates of 5 or more per second. Available in disposable injection molded wetted parts for solvent-free cleanup.
 
Adjustable needle valve designed to dispense very precise deposits over a wide range of shot sizes, down to a fraction of a milliliter.
 
A micro shot valve provides a high degree of control for continuous or micro shot applications of low to semi-viscous fluids. The "ON/OFF" control is achieved by automatically opening and closing (pinching) a molded polyethylene tube assembly.
