Features and Applications of Pneumatic Three-way Valve Structure
1. Compact structure, quick opening and closing, smooth flow passage, and low fluid resistance.
2. Excellent sealing performance: The four-sided valve seat material, polytetrafluoroethylene, can deform elastically to achieve leak-free sealing.
3. Multi-purpose: Any of the three ports can be used as an inlet without leakage. The three-way valve can be made with either L-shaped or T-shaped ports.
4. Easy maintenance: After the system is depressurized, inspection and maintenance can be carried out without removing the entire valve body.
5. Widely applicable in pipeline systems such as water supply, petrochemical, metallurgy, mining, light industry, energy, papermaking, food, steel, etc., for switching the direction of the medium flow and for splitting or mixing the medium.
The flow principle of the pneumatic three-way ball valve
The three-way ball valve is divided into L-type and T-type. The direction of medium flow is shown in the following figure. The L-type three-way ball valve is suitable for the switching of medium flow direction, enabling the connection of two perpendicular channels: The T-type three-way ball valve is suitable for the diversion, confluence or flow direction switching of the medium. The T-shaped channel can connect the three channels or connect two of them. The three-way ball valve generally adopts a two-seat structure, and can also be designed with a four-seat structure according to user requirements.
Pneumatic three-way ball valve standard
I. Design and manufacture: GB/T12237-1989; API 1608.
2. Inspection and testing: GB/T13927-1992; API 1598.
3. Flange connection: JB/T79-2-1994; ASME/ANSI B165.
4. Structural length: JD-2002
Pneumatic three-way ball valve actuator: It adopts the new series GT type pneumatic actuator, which has double-acting type and single-acting type (spring reset), gear transmission, and is safe and reliable; for large-diameter valves, it uses the series AW type pneumatic actuator with fork transmission, which has a reasonable structure, large output torque, and is available in double-acting type and single-acting type.
1. Gear type double piston, with large output torque and small volume.
2. The cylinder is made of aluminum alloy material, which is lightweight, has a beautiful appearance.
3. Manual operation mechanism can be installed at the top or bottom.
4. Toothed bar connection can adjust the opening angle and rated flow.
5. The actuator can be selected with electrical signal feedback indication and various accessories to achieve automatic operation.
6. The IS05211 standard connection provides convenience for the installation and replacement of the product.
7. The adjusting screws at both ends can make the standard product have a ±4° adjustable range from 0° to 90°. This ensures the synchronization accuracy with the valve.
The stainless steel pneumatic three-way ball valve is widely used in water supply, petrochemical, metallurgy, mining, textile, energy, papermaking, food, steel and other pipeline systems. It is used to switch the flow direction of the medium and to split or mix the medium. It is divided into L type and T type. The L type is suitable for switching the flow direction and can connect the two perpendicular channels; the T type is suitable for splitting, merging or flow direction switching, and can connect the three channels or make two of the channels connected.
