Product Introduction

The BS1873 cast steel globe valve is designed for precise flow regulation and reliable throttling control in demanding industrial pipeline systems. It is widely used in oil & gas, petrochemical, power generation, and process industries where stable flow adjustment is critical.

Unlike isolation valves, this globe valve is engineered for controlled flow modulation under high pressure and temperature conditions, ensuring operational stability and safety in severe service environments.

Technical Overview

Size range:	DN50–DN600 (NPS 2"–24")
Pressure rating:	Class 150 to Class 2500
Body materials:	WCB / WC6 / WC9 / CF8M
Temperature range:	-29°C to +600°C (material dependent)
End connections:	Flanged or butt weld

Working Principle

The valve controls flow through a linear motion disc mechanism. As the disc moves toward or away from the seat, the flow passage is gradually adjusted, enabling precise throttling.

The internal flow direction change enhances control accuracy, making it ideal for regulation rather than on/off isolation.

Typical Applications

Steam control in power plants

Refinery and petrochemical process lines

Boiler feedwater regulation

Chemical injection and corrosive media systems

High-pressure industrial utility pipelines

Material Selection

Trim options can be selected for erosion resistance and long-cycle throttling service.

WCB

General industrial oil, gas, and steam service

WC6 / WC9

High-temperature steam and power applications

CF8M

Corrosive chemical and seawater environments

Testing & Quality Assurance

Each valve is tested according to API 598 standards, including:

Shell hydrostatic test
Seat leakage test
Dimensional inspection
Material traceability (MTC available)

Ensures reliability for critical industrial applications.
