Four-way Ball Valve

A four-way ball valve is an advanced flow control device featuring four ports, enabling simultaneous management of multiple fluid pathways within a single valve body. Unlike standard 2-way or 3-way valves, our four-way ball valve utilizes a precision-engineered spherical disc (with X-shaped or L-shaped internal channels) that rotates 90° to control, divert, or mix fluid flow efficiently. This innovative design eliminates the need for multiple valves and complex piping configurations, reducing installation space, cost, and operational complexity-making it an ideal choice for modern industrial systems.

Our four-way ball valve is available in manual, pneumatic, or electric operation modes, supporting both on-site and remote control to adapt to diverse automation requirements. Crafted with high-quality materials and strict manufacturing standards, it ensures leak-free performance, long service life, and compatibility with a wide range of media and working conditions.

1.Multi-Path Flow Control : Equipped with X-shaped or L-shaped internal channels, the valve can easily switch, divert, mix, or reverse fluid flow between four ports-replacing complex valve groups and simplifying system design. For example, in power station cooler systems, it can replace four separate valves to realize forward and reverse water supply switching with a single operation, saving time and reducing operational errors.

2.Superior Sealing Performance : Adopts top-mounted fixed ball structure and high-quality sealing materials (special plastic, PTFE, or hard metal seal) to ensure excellent airtightness and wear resistance. The sealing force increases with medium pressure, effectively preventing leakage even under high-pressure and high-temperature conditions, and maintaining system integrity.

3.High Efficiency & Easy Operation : 90° quarter-turn operation enables quick flow switching, with smooth operation and small driving torque. It supports manual, pneumatic, and electric operation modes, and can be switched to manual operation when needed, ensuring flexibility in various working scenarios. The control system features clear indicators (power, flow direction, fault alarm) for intuitive operation and easy monitoring.

4.Robust & Durable Construction : Valve body, bonnet, ball, and stem are made of high-quality materials such as cast steel, 304/316 stainless steel (austenitic or martensitic), offering excellent corrosion resistance, wear resistance, and high-temperature resistance. The one-piece trunnion-mounted ball and stem design eliminates shear failure common in two-piece designs, further extending service life.

5.Low Fluid Resistance & Energy Saving : The full-port flow path and arc connection of the internal channel ensure smooth fluid flow, minimizing pressure drop and energy consumption-improving overall system efficiency. It is suitable for both liquid and gas media, with no media accumulation, facilitating pipeline cleaning and maintenance.

6.Wide Compatibility & Standard Compliance : Designed and manufactured in accordance with international standards such as GB/T12237, API 6D, ASME B16.34, DIN 3357, and BS 5351, ensuring interchangeability and compatibility with global industrial systems. Available in various sizes, pressure classes, and connection methods to meet diverse project requirements.
