Pneumatic High-Temperature Control Valve

The pneumatic high-temperature control valve consists of a multi-spring pneumatic diaphragm actuator and a low-flow-resistance high-temperature valve body. The multi-spring actuator features a low profile, light weight, and simple installation. The valve body's flow passage adopts an S-shaped streamlined design, offering advantages such as compact structure, light weight, responsive operation, minimal pressure drop, high valve capacity, accurate flow characteristics, and easy maintenance. It is suitable for demanding operating conditions.

Product Details

Pneumatic high-temperature control valves, when paired with electro-pneumatic valve positioners or pneumatic valve positioners, enable automatic regulation and control of fluid media within process pipelines. These valves are widely used to precisely maintain process parameters—such as pressure, flow rate, temperature, and liquid level—at specified values for gases, liquids, and steam. They are particularly suitable for applications requiring minimal leakage, moderate pressure differentials across the valve, and high-temperature environments.
