BS1873 Class 1500 ANSI Flanged High Pressure Angle Globe Valve

Product Overview

The BS1873 Class 1500 ANSI Flanged High Pressure Angle Globe Valve is a professional ultra-high pressure throttling and cut-off valve strictly designed and manufactured in accordance with BS1873 British standard and ASME American industrial standards. Different from straight-type globe valves, this angle globe valve adopts a unique 90° inlet and outlet vertical structure, perfectly matching angle pipeline layout, effectively changing medium flow direction while realizing precise throttling and safe cut-off.

Class 1500 ultra-high pressure grade and thickened integral cast steel structure enable the valve to withstand extreme high-pressure and high-temperature working conditions. Complying with BS1873 specifications for petroleum and petrochemical industrial steel valves, it features stable pressure-bearing performance, anti-scouring and anti-corrosion capabilities. The optimized internal flow channel reduces fluid resistance and medium impact, avoiding pipeline pressure surge. It is widely used in ultra-high pressure process pipelines, steam systems and heavy-duty industrial fluid control scenarios, serving as a core safety control valve for harsh working conditions.

Key Features & Advantages

1. Strict BS1873 Standard Certification

Manufactured fully per BS1873 standard for petrochemical industrial steel globe valves, compliant with ASME B16.34 pressure-temperature rating, ASME B16.10 face-to-face dimension and ASME B16.5 flange standards. All design, manufacturing and testing procedures meet international industrial acceptance criteria, suitable for global high-end energy and chemical engineering projects.

2. Class 1500 Ultra-High Pressure Resistance

Customized for Class 1500 ultra-high pressure working conditions, the valve adopts thick-wall integral casting and reinforced pressure-bearing structure. It stably resists long-term extreme pressure impact and cyclic load operation, effectively preventing valve body deformation, structural damage and sealing failure, ensuring safe and stable operation of ultra-high pressure pipelines.

3. Professional 90° Angle Flow Design

Unique angle-type structural design realizes 90° fluid steering, perfectly adapting to corner pipeline installation. It simplifies pipeline layout, reduces elbow accessories and pipeline pressure loss, and avoids medium dead angle. The flow channel is smooth and wear-resistant, effectively improving pipeline fluid transmission efficiency.

4. Premium Cast Steel Material Option

Optional ASTM A216 WCB carbon steel, WC6, WC9 alloy steel and other high-pressure resistant materials. The valve body has excellent high-temperature mechanical stability, strong medium scouring resistance and structural toughness, adapting to long-term ultra-high temperature and high-pressure cyclic operation without structural failure.

5. Standard ANSI Flanged Connection

Equipped with ANSI B16.5 standard flange (RFRTJ optional), with precise sealing surface processing and unified international installation dimensions. The flanged structure is easy to install, position and disassemble, convenient for daily maintenance and pipeline overhaul, with excellent vibration resistance and sealing stability.

6. Precise Throttling & Zero Leakage

The valve disc and seat adopt precision lapping process, with optional Stellite hard alloy overlay to enhance high-temperature wear resistance and scouring resistance. It realizes linear accurate flow regulation and bidirectional tight shutoff. All products pass strict API 598 hydrostatic and sealing tests to achieve bubble-tight zero leakage.

What Is a High Pressure Globe Valve

A High Pressure Globe Valve is a linear motion valve designed for regulating and isolating flow in pipelines carrying liquids, gases, and steam under elevated pressure conditions. It uses a movable disc that presses against a seat to control flow with high precision. The body and internal components are engineered with strong materials to withstand severe operating stress. This type of valve is widely applied in power generation, petrochemical processing, refinery systems, and high pressure steam networks.

Why the High Pressure Globe Valve Matters

This valve is important because it provides accurate flow control and reliable sealing in demanding high pressure environments. Its design allows stable regulation of process conditions while protecting downstream equipment from pressure fluctuations. Strong structural integrity ensures safe operation under harsh working conditions. The valve plays a key role in systems where precise throttling and dependable shutoff are essential for operational safety and efficiency.

Common Product Types by High Pressure Globe Valve

Common product types include standard pattern globe valves, angle globe valves, and Y pattern globe valves designed for high pressure service. Bonnet structures may include bolted bonnet, pressure seal bonnet, or welded bonnet configurations. Operation methods include manual, electric, pneumatic, and gear driven designs. Different trim materials and hardfaced sealing surfaces are used to handle high temperature, corrosive fluids, and erosive media.

Key Advantages of High Pressure Globe Valve

The valve offers precise throttling capability, stable operation, and strong resistance to pressure stress. Its internal structure allows accurate flow adjustment and reliable shutoff performance. Durable seat and disc materials provide long service life under severe conditions. The robust body design enhances safety, while multiple actuation options offer flexibility for various industrial control systems.

High Pressure Globe Valve Machine Structure and Core Stations

Manufacturing begins with forging or casting the body, bonnet, disc, and stem from high strength alloys. Core stations include heat treatment and CNC machining of sealing surfaces, stem threads, flow passages, and connection ends. Hardfacing may be applied to critical wear areas. Assembly stations install the disc, stem, packing system, bonnet, and actuator interface. Final processes include pressure testing, surface finishing, cleaning, marking, and packaging to ensure dimensional accuracy and reliable sealing performance.
