Steam Globe Valve
Product Description
Vcore steam globe valve is engineered for specialized applications requiring temperature maintenance or freeze protection. Our valve is equipped with a steam jacket welded around the valve body, ensuring that the fluid medium remains at optimal temperature throughout operation. It combines precise flow control with heat preservation, making it ideal for industries where viscosity or crystallization is a concern. The body adopts a forged or cast steel construction with a globe-style closure mechanism for robust sealing and minimal leakage.
Key Features
-
Full Steam Construction: Valve body and bonnet are fully jacketed to ensure medium temperature remains consistent throughout operation.
-
Excellent Thermal Efficiency: Steam or thermal oil circulates through the jacket to prevent crystallization or solidification.
-
Versatile Connection Options: Available in flanged, butt-welded (BW), or socket-welded (SW) ends to meet diverse pipeline requirements.
-
Reliable Shutoff Performance: Hardened sealing surfaces and precision lapping provide secure closure and long service life.
-
High Material Compatibility: Body and jacket materials include carbon steel, stainless steel, or alloy steel for different process conditions.
-
zEasy Maintenance: Bolted bonnet and replaceable seat/disc design allow for quick inspection and servicing.
-
Compact and Robust Design: Optimized structure for minimal heat loss and excellent mechanical strength under high pressure.
