Trunnion Ball Valve

The trunnion ball valve has the design of dual blocking and discharge services, as both upstream and downstream valve seats float independently. The trunnion design usually uses a valve seat lubrication port, and lubricant can be injected around the valve seat to help with the closing effect. The trunnion ball valve has low fluid resistance and will not get stuck during operation (in the absence of lubricants), making them reliable for use in corrosive media and low boiling liquids.

Design Advantages

Good sealing performance, small opening and closing torque.

The lowest flow resistance, close to zero.

When quickly opening and closing the valve, there is no impact during operation.

The trunnion ball valve is equipped with fire and anti-static devices.

Anti spray design prevents the stem from spraying out from the valve body due to improper operation.

The valve stem can be extended according to installation or operation needs.
