Overview

The X14 series female threaded three-way plug valve is a type of valve that switches, distributes, opens, or closes fluid passages through the rotary motion of a tapered or cylindrical plug. The valve adopts a three-way structure, with L-shaped or T-shaped medium flow ports provided on the plug. By rotating the plug 90 or 180 degrees, the flow ports align with or become offset from different passages of the valve body, thereby achieving flow direction change, merging, or diverting. The valve stem is integrally or fixedly connected to the plug. During operation, the stem and plug rotate synchronously without any lifting motion. Packing sealing is provided between the stem and the valve body to ensure reliable external sealing. Both ends and the side port of the valve body adopt female threaded connections, which can be directly connected to external threads of pipelines, making installation and disassembly convenient and suitable for small and medium-diameter pipeline systems. The valve relies on precise fit and lubrication or resilient sealing materials between the plug and the valve body sealing surfaces to achieve sealing, offering low operating torque and stable sealing performance. With a compact structure, it is widely used in pipeline systems handling water, oil, gas, and other non-corrosive or mildly corrosive media for flow direction switching or distribution purposes.

Feature

1. Female Threaded Connection for Easy Installation: Both ends and the side port of the valve body adopt female threaded connections, which can be directly connected to external threads of pipelines, making installation and disassembly convenient. Suitable for small and medium-diameter pipeline systems without the need for flange welding.

2. Three-Way Switching with Flexible Flow Path: L-shaped or T-shaped flow ports are provided on the plug. A 90-degree or 180-degree rotation of the plug completes flow direction change, merging, or diverting, providing rapid operation. Various flow control modes can be achieved according to process requirements.

3. Reliable Sealing Performance: The sealing surfaces of the plug and valve body can be precision-lapped or lined with resilient materials such as PTFE, achieving excellent sealing effect with self-lubricating properties and smooth operation.

4. Corrosion and Wear Resistance: The valve body and plug can be made of carbon steel, stainless steel, brass, alloy steel, or other materials depending on the medium. Sealing surfaces can be hardened (e.g., hardfacing with cemented carbide, nitriding, etc.), providing wear resistance, erosion resistance, and long service life.

5. Non-Rising Stem Design, Compact Installation Height: The stem and plug rotate as one unit without axial movement, resulting in a low overall height, suitable for pipeline systems with limited installation space.
