Highlight: Manual two-piece threaded copper ball valve
Product introduction:
Ball valve is a ball with a circular channel as the opening and closing parts, the ball with the stem rotation to realize the opening and closing action of the valve. The opening and closing part of the ball valve is a perforated sphere that rotates around the axis perpendicular to the channel to achieve the purpose of opening and closing the channel. Ball valves are mainly used for opening and closing pipelines and equipment media.
Ball valves can be closed tightly with only a 90 degree rotation operation and a small torque of rotation. The completely equal body cavity provides the medium with small resistance and straight flow channel.
