Three piece ball valve and gate valve flange butt welding is the same type of valve, the difference in its closure is a sphere, the sphere rotates around the body center line to achieve the opening and closing a valve. Ball valve in the pipeline is mainly used to do the cutting, distribution and change the direction of the flow of media. Two piece ball valve, three piece ball valve, is widely used in recent years, a new type of valve, the valve in the pipeline should generally be installed horizontally.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
