Introduction

We are one of leading control valve manufacturers in China, delivering high-quality valves and control actuators designed to meet a wide range of industrial applications.
In the fast-paced world of industrial automation, efficiency, reliability, and precision are essential. The pneumatically controlled 3-way ball valve (L-port) marks a major advancement in fluid control technology. Designed to replace manually operated valves, this innovative valve integrates effortlessly into automated systems, enhancing performance while reducing operational costs. With a 10 mm diameter and the ability to handle both liquids and gases across a temperature range of -10°C to 100°C, it offers versatile applicability across various industries.

Unmatched Performance and Durability

At the core of this 3-way ball valve lies a powerful pneumatic actuator, delivering a torque of 9.92 Nm at 8 bar and operating efficiently within a control pressure range of 6 to 10 bar. Featuring G 3/8" threaded connections, it ensures easy installation with existing piping or tubing systems. The valve’s Kv value of 3 m³/hr guarantees optimal flow regulation for precise process control.

Its double-acting actuator utilizes a durable aluminum rack-and-pinion mechanism, providing superior responsiveness and control compared to single-acting designs. This allows for fast, accurate valve actuation—critical in applications where timing and precision matter. The anodized aluminum housing offers excellent corrosion resistance and durability, while the acetal resin cover protects against wear, extending service life.

Constructed with a brass valve body renowned for strength and pressure resistance, the valve is sealed with PTFE (polytetrafluoroethylene), offering outstanding chemical resistance and low friction. This combination enables the valve to withstand media pressures up to 40 bar, making it suitable for the most demanding industrial environments.

Seamless Integration and Control

Designed for convenience, this valve supports direct mounting of Namur solenoid valves via its G1/8 air supply and return ports, minimizing the need for extra fittings or tubing. This streamlined setup reduces installation complexity and potential leak points. A mechanical indicator on the actuator provides clear, real-time visual feedback on valve position, enabling quick operational checks.

Certified for Safety and Reliability

Safety is paramount in hazardous industrial settings. This 3-way pneumatic ball valve is ATEX (EX II 2GD c) certified, rigorously tested for use in explosive atmospheres. This certification ensures the valve meets stringent safety standards, giving operators confidence in its reliability under the most challenging conditions.

Cost-Effective Automation

While electric actuators often lead automation solutions, this pneumatic ball valve presents a highly cost-effective alternative. It requires a lower initial investment, making automation accessible without compromising on performance. The double-acting actuator provides rapid valve operation and precise control, enhancing system responsiveness and efficiency.

However, it’s important to consider that double-acting actuators consume more compressed air than single-acting models, which may lead to higher ongoing energy costs. Additionally, a compressed air supply and solenoid valve are necessary to operate the system, potentially requiring infrastructure upgrades. Despite these factors, the overall value and performance benefits make this valve an excellent choice for many applications.

Enhanced Control with Limit Switch Box Option

For applications demanding advanced monitoring, the valve can be fitted with an optional limit switch box. This accessory delivers real-time feedback on valve position, enabling precise control and seamless integration with automated control systems. It’s ideal for processes requiring continuous position monitoring or remote system optimization.
