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.
