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

Product Name: High-temperature Steam Control Valve
Body Material: ASTM A105
Size: DN40, 1-1/2 Inch
Pressure: PN64, Class 400 LB
End Connection: Flanged
Operation: Multi-spring Diaphragm Pneumatic Actuator
Characteristic: Linear, Equal Percentage

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.
