  • Higher lift increases flow, cuts energy usage by an average of 10%
  • Damping ring reduces impact forces for longer valve life
  • Precision-engineered springs ensure timely closing
  • Standard threaded washer facilitates valve installation and removal
  • Maximum flow is achieved through optimum combination of port row widths and pitch circles
  • Reinforced plate material protects against impact fatigue
  • Heavy-duty springs withstand high speeds and lifts up to 0.150 inch (3.8 mm)
  • Superior materials provide high resistance to corrosion and wear
