Q644F Pneumatic Three-Way Ball Valve
Other Products
I. Introduction:
Pneumatic three-way ball valves use pneumatic actuators to drive the ball, achieving directional control through a 90-degree rotation, or directional control as well as diversion and confluence control through a 180-degree rotation. The pneumatic actuators for ball valves adopt the new AT/GT series pneumatic actuators, whose structure has obtained the national utility model patent. They are available in double-acting and single-acting (spring return) types, with a rack-and-pinion transmission structure, ensuring safer and more reliable performance. For large-diameter valves, AW series pneumatic actuators are used, featuring a fork-type transmission structure with a reasonable design and large output torque. Ball valves are divided into L-type and T-type. L-type ball valves are suitable for switching the flow direction of the medium, enabling communication between two mutually perpendicular channels. T-type ball valves are suitable for medium diversion, confluence, or flow direction switching; the T-type channel can connect three channels with each other or two of them. Pneumatic three-way ball valves generally adopt a two-seat structure, and a four-seat structure can also be used according to user requirements.
II. Features:
1. Compact structure, quick opening and closing, unobstructed flow path, and small fluid resistance.
2. Easy maintenance: After depressurizing the system, inspection and maintenance can be carried out without removing the entire valve body.
3. Good sealing performance: Leakage-free sealing is achieved through the elastic deformation of the polytetrafluoroethylene (PTFE) material of the four-sided valve seat.
4. Anti-static function: A spring is installed between the ball, valve stem, and valve body to conduct static electricity generated during the opening and closing process.
5. Multi-function of one valve: Any port can be used as an inlet without leakage; the three-way valve can be made into either an L-type port or a T-type port.
6. Due to the excellent self-lubricating properties of materials such as PTFE, the friction loss with the ball is small, so the service life of the ball valve is long.
