DK

Serves as efficient stop valves with flow in either direction. They are commonly used where a minimum of
pressure drop is important because they offer typically no resistance to flow when fully open. Throtting is not
conductive to accurate and consistent flow control. Also the valves may be damaged by the high velocity across
the seats. They function best fully open or fully closed.
