Valve precisely dispenses miniature beads

A Sealant Equipment and Engineering product story
Edited by the Engineeringtalk editorial team Mar 24, 2006

Two-component miniature mix-dispense valve precisely dispenses miniature beads and very small volumes of low-viscosity pourable materials and abrasive or filled materials.

Sealant Equipment and Engineering's Model 2200-545-037 two-component miniature mix-dispense valve precisely dispenses miniature beads and very small volumes of low-viscosity pourable materials and abrasive or filled materials.

The valve is for low-flow applications typically found in miniature potting, doming, filling and bonding operations.

It uses no-drip technology for dispensing solvent-based, moisture-curing and stringy materials such as epoxies, silicones and polyurethanes in difficult product-assembly applications.

The pneumatically actuated valve opens and closes its carbide resin- and catalyst-material passages at the mixer entrance to start and stop material flow.

The valve has stainless-steel wetted components, dual carbide ball-and-seat shut-off, safety-closure spring, flow-control adjustment and balancer eye-hook.

The valve's stroke adjuster can set the needle opening to adjust material-flow rates.

Wear-resistant fluid seals extend valve life.

Precision dowel and screw holes allow easy and accurate mounting.

For optimum material mixing, the valve's quarter-turn bayonet mount accommodates many disposable mixer sizes.

A typical bayonet-mount mixer used is a 17-element disposable mixer, 0.3175cm diameter, 6.25cm long and 0.076cm outlet orifice.

Resin and catalyst materials are delivered on-ratio to the valve by the firm's Servo-Flo metering assembly fed by supply tanks or pumps.
