News

Model 2200-545-037 two-component Miniature Mix-Dispense Valve precisely dispenses miniature beads and small volumes of low-viscosity pourable materials and abrasive or filled materials. Ideal for low-flow applications typically found in miniature potting, doming, filling and bonding operations.

The valve 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 precisely start and stop material flow.

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.

Quarter-turn bayonet mount accommodates many disposable mixer sizes. A typical bayonet-mount mixer used is a 17-element disposable mixer, 0.125” diameter, 2.46” long and 0.030” outlet orifice. Resin and catalyst materials are delivered on-ratio by Servo-Flo metering assembly fed by supply tanks or pumps.
