Dye DFF-20 Lazarus Valve


The New Dye DFF-20 Autococker valve from DYE is a DYELAB secret project that we referred to internally as code name “Lazarus valve”.  With years of Autococker tuning and high-level valve experience our talented engineering staff took a contemporary engineering approach to improve and create an 11/16” bore Autococker valve that offers several advantages, including increased air efficiency, smoother operation, and improved shot consistency.  This contemporary approach led to the design of the DFF-20 “Lazarus Valve”; it is a well-designed component for paintball enthusiasts looking to enhance the performance of their markers.  This valve is designed to fit modern Autococker bodies with an 11/16" valve bore.


  • Fits: Modern Autococker bodies that feature the 11/16” valve bore.
  • Balanced Valve Design: This design reduces the force required to open the valve and allows the valve to seal at very low pressure.
  • Reduced Hammer Spring Force: Spring for reduced by up to 2 pounds, which can contribute to smoother firing operation.
  • Breach Sensing Technology: Increases the valve closing speed, leading to improved air efficiency, ultra quiet shot, and eliminates wasted air.
  • Lower LPR Pressure: Allows for lower LPR (Low-Pressure Regulator) pressure, resulting in a smoother firing cycle.
  • Large Valve Diameter: With a massive .400" valve diameter, it eliminates low flow conditions, enhancing efficiency and consistency.
  • Oversized Porting and Flow Path: This feature eliminates flow restrictions and further improving efficiency.
  • Shot-to-Shot Consistency: The valve offers incredible shot-to-shot consistency, which is crucial for accuracy.
  • Standard O-Ring for Valve Face Seal:  The use of a standard 011 90D o-ring for the valve face seal makes it easy to perform rebuilds and maintenance.
  • Fully Supported Valve Stem:  This provides exceptional stability and reliability during operation.
  • Opening Speed and Lift:  These aspects remain unaffected by the operating pressure, ensuring consistent performance.
