High-temperature Steam Control Valve, ASTM A105, DN40, PN64

Key Specifications / Features

The High-temperature Steam Control Valve is engineered for precise regulation of steam flow in high-temperature environments. Made from ASTM A105 carbon steel, this 1-1/2 inch (DN40) valve operates at PN64 and Class 400 LB pressure ratings, ensuring reliability under extreme conditions. It features flanged ends for secure installation and is equipped with a multi-spring diaphragm pneumatic actuator for smooth, automated control.

The Pneumatic High-Temperature Steam Control Valve is a top-entry, globe-type valve with flange or welding connections and a cage-type seat. The valve body features a streamlined S-shaped channel, offering low-pressure loss, high capacity, a wide regulating range, and high accuracy in flow characteristics. The plug is designed with a guiding area for enhanced vibration resistance. Equipped with a multi-spring diaphragm actuator, the valve has a compact structure and delivers high output force. It is suitable for controlling various fluids, including steam, water, and gases.
