A ball valve 4 inch is a quarter-turn on/off device. A pivoting ball in the center of the valve controls the flow of liquid or gas media.
The pivoting ball is known as a rotary ball, and it is designed with a hole (a bore) in the center. A stem on the top of the ball rotates the ball to open or close the valve. The stem can be turned using manual levers or automation.
ZECO 4 inch ball valve is also the most common batch product, which is mainly floating ball valves. Occasionally, fixed ball valves may be used due to special working conditions. ZECO and the National Pump and Valve Testing Center are long-term strategic partners. ZECO regularly sends samples of products for routine use to the testing center for testing every year to verify that the products have not changed due to any possible changes in the long-term production process.
