Features

  • Dual range throttling - primary range plus a super capacity blast range.
  • Rapid energy dissipation - controls the destructive forces inherent in high pressure drop service.
  • Accurate and repeatable settings - micrometer dial assures setting accuracy and positive resetting capability.
  • Quick-change disc - insert an interchangeable stem-disc into the same valve body to convert from one orifice size to another.
  • Guided-disc - eliminates disc vibration and chatter.
  • Loose disc: Disc design provides multiposition seating and assures positive alignment of seat and disc surfaces. This gives sure protection against premature failures from seat-to-disc “grind” prevalent in valves of integral stem-disc design.
  • Dual-purpose disc - separate surfaces for shutoff and throttling.
  • Stellite seat - resists corrosion and wiredrawing.
  • In-line repair - Yarway reseating tool can be used to cut a new seat in-line.
  • Resetting capability: The Hy-Drop® valve has positive resetting capability to accommodate multiple-operation programs with accurate flow control variations.
  • In-line repair:Yarway reseating tool can be used to cut a new seat without removing the valve from the piping.
  • Motor actuation: For local or remote operation.
