Pneumatic ball valves are essential components in industrial control systems, offering reliable and efficient on-off operation. The Q641 Pneumatic On-Off Ball Valve is a high-precision device that combines a robust pneumatic actuator with a precision-cast ball valve body. It is available in two main types: soft-sealed and metal-sealed, each designed for different application requirements.
This valve is ideal for applications involving viscous media, particles, or fibrous materials, making it suitable for industries such as petrochemicals, pharmaceuticals, water treatment, and more. It can be controlled using either electric or pneumatic actuators, and it supports both on-off and continuous signal control modes. When paired with accessories like limit switches, solenoid valves, and pressure regulators, the valve can achieve accurate remote or local control.
The valve is equipped with a dual-piston gear rack actuator, which ensures quick and stable operation. Its aluminum alloy cylinder provides durability and resistance to corrosion. The actuator design allows for easy adjustment of the valve position and offers multiple mounting options for accessories like positioners, limit switches, and transducers.
Key specifications include a nominal diameter range from DN15 to DN300, with working pressures up to 6.4 MPa. The valve undergoes rigorous testing, including strength and sealing tests, ensuring long-term performance under various conditions. It is compatible with a wide range of media, including water, oil, steam, nitric acid (up to 200°C), and acetic acid (up to 200°C).
The product is certified with CE, SGS, and ISO standards, and it is manufactured in Tianjin, China. It is packaged in wooden cases or cartons for safe transportation. With its compact design, low flow resistance, and excellent sealing properties, this pneumatic ball valve is a versatile and reliable choice for industrial automation systems.
