Description

2 inch Ball Valves are normally floating ball valves according to API 6D, API 608 standard

What is 2 Inch Ball Valve?

ZECO 2 inch ball valve is usually a floating ball valve and is available in brass ball valve, cast steel ball valve and forged steel ball valve.

A 2 inch floating ball valve gets its name from the ball-like sphere that “floats” freely inside the valve’s body, which is compressed between two flexible seats while suspended in liquid. What a floating ball valve normally does during operation is float slightly downstream, which causes the seating mechanism to compress under the ball. Should the seating disintegrate, the ball floats to the metal stem to seal it. This provides a failsafe within the design.
