Electric Forged Steel Control Valve
Description
Electric Forged Steel Control Valve – Technical Datasheet
1. Product Overview
This product is a high-performance Electric Forged Steel Control Valve, designed for precise flow regulation and shut-off in high-pressure and high-temperature industrial pipelines. As shown in the provided images, it features a robust forged steel body (characterized by its compact, square profile), flanged connections, and a smart electric actuator. The actuator is equipped with a blue manual override, a clear position indicator window, and local control buttons. The forged construction provides superior structural integrity and safety compared to cast steel, making it ideal for critical applications in power plants, petrochemical, and high-pressure steam systems.

5. Key Features
-
Superior Forged Steel Body: The forged construction (A105 or F304/F316) eliminates casting defects such as porosity and sand holes, offering higher tensile strength and reliability for high-pressure applications.
-
Smart Electric Actuator: Equipped with a high-precision electric actuator featuring a transparent display window, local control buttons, and a blue manual override for emergency operation.
-
Precise Flow Control: Available with 4-20mA analog signals or digital communication protocols (Modbus, Profibus) for accurate modulating control, ensuring optimal process efficiency.
-
Compact & Robust Design: The square forged body and integrated yoke design significantly reduce the valve’s overall footprint, making it ideal for space-constrained installations.
-
Excellent Sealing Performance: The precision-machined plug and seat (with optional Stellite overlay) provide excellent shut-off capability, meeting ANSI Class IV, V, or VI leakage standards.
-
Easy Maintenance: The modular design of the actuator and valve body allows for quick disassembly and maintenance of internal components without removing the entire valve from the pipeline.
