Ball Valves

Ball valves Manufacturer

With so many different types of valves on the market today, it can be difficult to decide which valve is most suitable for your application. In this article, HPValves explores the merits of ball valves.
Selecting the best valve can make or break your system. Ball valve and gate valves are both designed to restrict and control flow. The ball valve is designed with a ball inside the valve. A ball valve is a form of quarter-turn valve which uses a hollow, perforated, and pivoting ball (called a “floating ball”) to control flow through it. It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve’s status.
If the ball valve is left partially open for an extended period under conditions of a high-pressure drop across the ball, the soft seat will tend to flow around the edge of the ball orifice and possibly lock the ball in that position.
