2200-545 Series adjustable stroke mix-dispense valves are designed for controlled flow of 2-component adhesives and sealants, such as silicones, epoxies, urethanes and acrylics. Are based on the No-Drip valve body design for fluid control, featuring the integration of carbide ball-end needles and carbide seats. The adjustable stroke feature permits the operator to fine-tune the flow rate 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. Are 2.25" in diameter by 5.5" long, and are rated for 3,500 psi (240 bar). Double air actuated with two 1/8 NPT ports for a 4-way pneumatic valve connections. Body has two 1/4 NPT fluid inlet ports for Part A and B materials and accepts a wide variety of motionless mixers; has two screw holes and two dowel holes.
