Cast Steel Flanged API Globe Valve - Industrial High Pressure Flow Control Valve

Product Overview

The Cast Steel Flanged API Globe Valve is a versatile industrial flow control valve engineered for high-pressure, general-service applications, adhering to strict API (American Petroleum Institute) standards for reliability and performance. Constructed with premium cast steel (WCB/WCC/A216) for exceptional strength and durability, this valve features flanged end connections for secure installation and a precision globe valve design for accurate flow regulation and tight shutoff. Compliant with API 600, API 598, and ASME B16.34 standards, it is widely used in oil & gas, petrochemical, power generation, and industrial piping systems, handling media such as steam, oil, gas, and water with operating pressures up to Class 2500 (PN 420) and temperatures ranging from -29℃ to 427℃. Designed to meet the rigorous demands of industrial operations, this valve balances performance, longevity, and cost-effectiveness for global customers.

Key Features & Advantages

1.High-Quality Cast Steel Construction

Manufactured from ASTM A216 WCB/WCC cast carbon steel (or optional alloy steel), the valve offers superior mechanical strength, impact resistance, and thermal stability. Cast steel’s excellent compatibility with diverse industrial media (neutral, alkaline, and non-corrosive fluids) makes it a cost-effective choice for general-service applications, while resisting wear and deformation under high pressure and temperature.

2.API Standard Compliance

Fully adheres to API 600 (Steel Globe Valves for Flanged End Connections) and API 598 (Valve Inspection and Testing) standards, ensuring dimensional accuracy, interchangeability, and leakage-free performance. API certification guarantees compliance with global industrial requirements, facilitating cross-border procurement and project approval.

3.Flanged End Connection for Versatility

Flanged ends comply with ASME B16.5 (NPS 1/2" - 24") or BS 4504 standards, supporting RF (Raised Face) or RTJ (Ring Type Joint) configurations. This design enables easy integration into existing industrial pipelines, secure leak-proof installation, and convenient disassembly for maintenance, compatible with standard flanges across pressure classes (Class 150 to 2500).

4.Precise Flow Control & Tight Shutoff

Globe valve’s linear motion plug-and-seat design provides accurate throttling and flow regulation, ideal for applications requiring precise media control (e.g., pressure regulation, flow rate adjustment). Precision-machined seating surfaces (with optional Stellite overlay) ensure tight shutoff (API 598 Class IV leakage standard), preventing media waste and system inefficiencies.

5.Robust & Low-Maintenance Design

Bolted bonnet construction with a backseat design allows in-line maintenance—inspection, repair, or replacement of internal components (stem, plug, seat)—without removing the valve from the pipeline. The one-piece forged stem ensures structural integrity, while the handwheel (or optional gear/actuation) offers smooth operation with minimal friction, extending service life.

6.Wide Operating Range

Suitable for working pressures from Class 150 (PN 10) to Class 2500 (PN 420) and temperatures from -29℃ (-20°F) to 427℃ (800°F), adapting to diverse industrial conditions such as high-pressure steam systems, oil pipelines, and chemical processing plants.
