Controls the destructive forces inherent in high pressure drop service through rapid energy dissipation.

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.
