The No-Drip design feature integrates carbide ball-end needles with carbide seats for long-life dispensing of low-viscosity abrasive materials. Sealant Equipment and Engineering’s 2200-545 series adjustable-stroke mix-dispense valves are designed for controlled flow of two-component adhesives and sealants such as silicones, epoxies, urethanes and acrylics. The valves are based on the company’s No-Drip valve body design for fluid control.

The No-Drip design feature integrates carbide ball-end needles with carbide seats for long-life dispensing of low-viscosity abrasive materials. The adjustable stroke feature allows the operator to fine tune the flow rate of the adhesive dispensing application by rotating the threaded stem on the back of the valve. The valve is also available with an eyelet stem for attaching to a tool balance.

The valves are 57mm, 140mm long and are rated to 240bar. The valves are double air actuated with two 1/8 NPT ports for four-way pneumatic valve connections. The divorced-design fluid body has two 1/4 NPT fluid inlet ports for Part A and B materials and accepts a wide variety of motionless mixers.

The valve bodies have two screw holes and two dowel holes for accurate mounting. The valves may be mounted to robot tooling, automation fixtures and electric or pneumatic valve handles. The valves are used to apply two-part adhesives and sealants for bonding, gasketing, coating, potting and filling processes in aerospace, appliance, contractor, defence, electronics, filters, marine, medical, sporting goods, automotive, truck and bus assembly dispensing applications.
