Spinner™ Valves    The Spinner™ valve is a direct replacement for a standard ball check valve, and features a 4-piece interlocking design.  Perfect for applications using non-filled resins, fast injection cycles & high speed screw rotation, the Spinner™ valve provides the latest technology for reliable performance.  When processing fluoropolymer applications, we recommend the Spinner™ design manufactured from ultra corrosion resistant Inconnel and/or Hastelloy materials.  For optimum flexibility, all Spinner™ parts are interchangeable with MALLARD® 4-piece standard & carbide-faced valves.
