The QJ41M integral high-temperature ball valve is designed specifically for high-temperature conditions and features high temperature resistance, wear resistance, and corrosion resistance. It is suitable for media such as steam, oil, hot oil, and acid.
● Easy to Operate: Rotating the sphere facilitates easy switching of actions without the need for additional tools or complex programs, significantly improving work efficiency.
● High Temperature Resistance: The valve body is usually made of high-quality cast steel, which enables it to work continuously and stably under harsh conditions such as high temperature, high pressure, and corrosive environments, thereby extending the service life of the equipment.
● Convenience: Compact structure, low installation space requirements, and simple installation process. In addition, maintenance costs are kept at a low level, and regular inspection and replacement of seals and other consumables are sufficient to ensure optimal operation.

Q1:What is the benefit of the floating ball design?
The floating ball design allows for smooth, efficient flow control as the ball moves with the flow of the fluid, ensuring minimal resistance and optimal performance.
Q2:What is the valve's temperature and pressure range?
The valve can handle temperatures from -40ºC to 300ºC (hard seal) or -40ºC to 180ºC (soft seal) and is rated for nominal pressures from PN1.6 to 6.4 MPa.
Our high-temperature ball valves are made of advanced materials and complex processes, ensuring excellent heat resistance and extended service life. They are designed to be compact, easy to install, and space saving, thereby minimizing time costs to the greatest extent possible. Each valve undergoes comprehensive quality testing to meet industry standards and ensure seamless operation. We provide comprehensive after-sales support, including technical consultation and repair services, to meet your needs in a timely manner.
