pk valve – Forged Steel Valves

Rubber Seat Butterfly Valves (Concentric Design)

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 practically no resistance to flowwhen fully open. Throttling is not conducive to accurate and consistent flow control. Also the valves may be damaged by the high velocity across the seats. They function best fully openor fully closed.
