September 2, 2008 - Sealant Equipment & Engineering's 2151-482 Series Servo-Mix Dynamic Mix and Dispense Valves are designed for precise mixing and dispensing two-component materials in robotic and semi-automatic product assembly processes. The dispensing applications include mixing epoxies, silicones and urethanes for bonding, gasketing, coating, potting and filling applications in aerospace, appliance, contractor, defense, electronics, filters, marine, medical, sporting goods, automotive, truck and bus assembly dispensing applications.The unique mixer design incorporates two features.
First, a standard disposable static mixer element is attached to the drive shaft of a variable speed servo motor for low to high speed mixing set by the operator on the control panel interface screen.The second design feature uses two of the company’s standard No-Drip® KISS Series fluid control valves to start and stop the flow of part-A and part B materials into the Servo-Mix dispense valve. These valves have carbide ball needles and seats for long service life with abrasive materials. The fluid control valves are used in place of typical check valves which are prone to leak and cause maintenance issues.
Also, the independent valves can be timed to reduce lead-lag issues and allow resin purging the mixer.The Servo-Mix Dynamic Mix Valve is available for ambient and controlled temperature dispensing applications for critical curing processes. A temperature control manifold assembly is available to maintain a material temperature set point incorporating a closed loop temperature transducer.Sealant Equipment & Engineering, Inc. is a leading manufacturer of precision fluid dispense systems and valves, is ISO 9001:2000 registered and designs, manufactures and integrates production-engineered dispensing systems to robotically, automatically and manually apply one- and two-component adhesives, sealants and lubricants for product assembly manufacturers worldwide.
