Quick Details 

General Description

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting 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.

Features

●Anti-static feature:  An anti-static mechanism is built in to conduct between the stem and body and the stem and ball. It prevents the valve from being catch fires when using flammable fluids.

●Fire-safe mechanism: Even if the ball seat (PTFE) is burned away, the fluid pressure still moves the ball and blocks the hole in the body, preventing further leaks.
