Steam Used High Temperature Pneumatic Globe Control Valve
Steam-Used High-Temperature Pneumatic Globe Control Valve – Features and Specifications
This high-performance pneumatic globe control valve is designed for use in steam systems, offering excellent control capabilities under extreme temperature conditions. It features a multi-spring pneumatic actuator combined with a low-flow-resistance sleeve, ensuring precise and stable operation. The balanced disc design minimizes unbalanced forces, allowing for higher allowable pressure differentials and improved performance. Compared to traditional single or double-seat regulating valves, this model offers reduced noise, a simpler structure, and easier assembly and maintenance.
The extended stem option makes it suitable for low-temperature applications as well. Its compact design, lightweight body, and robust performance make it ideal for industrial control systems that handle common fluid media. This new generation of general-purpose control valve is highly versatile and reliable.
**Key Features:**
- Balanced disc design for minimal unbalanced force
- Low noise operation
