Motorized Wafer Floating Ball Valve

The electric wafer floating ball valve has a simple structure, consisting of only a few parts, which saves material consumption. It is small in size, lightweight, has small installation dimensions, and requires low drive torque. It is easy and quick to operate, needing only a 90° rotation for rapid opening and closing. Additionally, it offers excellent flow regulation and sealing characteristics. In the field of medium and large diameters and low to medium pressure applications, the electric ball valve is the predominant type of valve. When the electric ball valve is fully open, the thickness of the butterfly plate is the only resistance the medium encounters as it flows through the valve body, resulting in a very small pressure drop, which gives it excellent flow control characteristics.

Wafer Ball Valve Advantage

1. Low fluid resistance: Ball valves have the lowest fluid resistance among all types of valves, and even reduced bore ball valves have relatively low fluid resistance.
2. Quick and easy operation: The ball valve can be fully opened or closed with a 90-degree rotation of the stem, enabling rapid opening and closing.
3. Good seat sealing performance: The sealing rings of ball valves are made from elastic materials such as PTFE, ensuring easy sealing. The sealing force of the ball valve increases with the pressure of the medium.
4. Reliable stem sealing: The stem rotates without lifting during the opening and closing of the ball valve, preventing damage to the stem packing seal. The sealing force of the back seal of the stem increases with the pressure of the medium.
5. Long service life: Materials like PTFE have good self-lubricating properties and low friction with the ball, extending the service life of the ball valve.
6. Various drive mechanisms: Ball valves can be equipped with pneumatic, electric, or hydraulic actuators for remote control and automation.
7. Smooth internal passage: The smooth and even passage inside the valve can transport viscous fluids and slurries.
8. Easy installation: Ball valves can be installed in any position on the pipeline in any direction.
9. Seat sealing characteristics: Floating ball valve seats are often made from polymer materials like PTFE and PEEK, which provide good sealing performance but are relatively soft. To achieve a certain sealing specific pressure, which can increase the torque required for opening and closing, the company uses double bevel elastic sealing rings or V-groove elastic sealing ring designs. The pressure in the pipeline helps to seal the ball. When the medium pressure is low, the contact area between the sealing ring and the ball is small, ensuring high sealing specific pressure for reliable sealing. When the medium pressure is high, the contact area increases, allowing the sealing ring to withstand greater medium thrust without damage. For low-pressure ball valves, where medium pressure cannot ensure reliable seat sealing and pre-tightening force diminishes over time, the valve is designed with a lip-shaped seat. This design uses elastic deformation principles to ensure reliable sealing performance and reduced torque.
