Working Principle

Forged Ball Valve is a valve with a spherical disc that controls the flow through it. The ball has a port through the middle so that when the port is aligned with the ends of the valve, the flow will pass through the valve. When the valve is closed, the hole is perpendicular to the end of the valve and the flow is blocked.

The trunnion mounted ball valve has additional mechanical anchoring at the top and bottom of the Forged Ball Valve for larger and higher pressure service. To ensure a tight seal at low pressure, a high tension spring forces the seat against the ball, while at higher pressures, the medium pressure pushes the upstream seat toward the ball.


We are willing to cooperate with colleagues at home and abroad to make contributions to the development of High Quality Forged Brass Ball Valve with Long Lever, 1/2 -4 Inch for the industry.
