Product overview
The three-way flange ball valve is mainly used to realize the channel switching function on the premise of cutting off or connecting the medium.
Product features
• the fluid resistance is small. The ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has very small fluid resistance.
• the switch is quick and convenient. As long as the valve stem rotates 90 °, the ball valve will complete the full opening or full closing action, which is easy to realize rapid opening and closing.
• good sealing performance. The sealing ring of ball valve seat is generally made of PTFE and other elastic materials, which is easy to ensure sealing.
• reliable valve stem sealing. When the ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easy to be damaged.
• the opening and closing of the ball valve only rotates 90 °, so it is easy to realize automatic control and remote control. It can be equipped with pneumatic actuator and electric actuator.
