A globe valve is a type of stop valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. Unlike gate valves, globe valves excel at flow regulation and throttling control.
Excellent throttling capability allows precise control of flow rate and pressure.
Spherical body design with disc provides superior sealing and minimal leakage.
Disc moves parallel to flow direction for precise control and positive shutoff.
The Globe Valve is a versatile linear-motion valve engineered for precise flow regulation and reliable shutoff in high-pressure pipeline applications, ideal for oil, gas, water, and chemical systems. Designed to API 602, ASME B16.34, and BS 1873 standards, this Industrial Globe Valve features a spherical body and disc-plug mechanism, providing superior throttling capabilities and tight sealing for pressures up to PN40 (Class 150-600) and temperatures to 425°C. Constructed from forged ASTM A216 WCB carbon steel or A351 CF8M stainless steel, it ensures excellent corrosion resistance with coatings like epoxy or 3LPE, making it suitable for refineries, petrochemical plants, and power generation facilities.
Precision-manufactured through forging or casting, the Pipeline Flow Control Valve undergoes stringent heat treatment and 100% non-destructive testing (RT, UT, MT, PT) to ensure structural integrity. Available in sizes from 1/2" to 24" (DN15 to DN600) with flanged, threaded, or butt-weld ends per ASME B16.5/B16.25, it supports manual handwheel or actuated operation with an outside screw and yoke (OS&Y) rising stem for clear position indication. The disc-plug, often hard-faced with Stellite #6, ensures abrasion resistance and bidirectional sealing, achieving Class VI shutoff per API 598. Hydrostatic shell tests at 1.5x rated pressure confirm tensile strengths above 485 MPa, ensuring durability under cyclic loading.
The Corrosion Resistant Globe Valve excels in throttling applications, offering precise flow control with minimal cavitation compared to gate or ball valves. Its globe-shaped body increases flow resistance for better regulation, ideal for steam, condensate, or viscous media. Enhanced with NACE MR0175 compliance for sour service, it resists H2S and chlorides in aggressive environments like offshore platforms. Optional features like bellows seals or pressure-seal bonnets enhance safety in high-temperature or hazardous applications. Face-to-face dimensions align with ASME B16.10 and BS EN 558 for seamless integration.
Compared to gate valves, the High Pressure Globe Valve provides superior flow modulation but higher pressure drop, making it ideal for applications requiring frequent adjustments rather than full-bore isolation. It outperforms ball valves in throttling precision, with 3-5 times longer service life in high-pressure, corrosive environments due to its robust disc and seat design. Customizable with pneumatic or electric actuators for automation, it suits remote operations in water treatment or chemical processing. Compliance with API 6FA for fire safety and SIL 3 for critical systems ensures reliability in demanding conditions.
Addressing challenges like pipeline corrosion, cavitation in throttling, and leakage under high pressures, the Globe Valve incorporates secondary seals and low-emission packing for enhanced safety. Its value-engineered design balances performance and cost, reducing maintenance in long-term projects. Whether regulating flow in steam boilers or isolating chemical lines, the Globe Valve delivers precise, reliable Pipeline Flow Control Valve solutions for global industrial needs.
Below are typical specifications for key materials in the Globe Valve, focusing on ASTM A216 WCB Carbon Steel for the body, ASTM A351 CF8M Stainless Steel for trim, and Stellite #6 for hard-facing. Data aligns with ASTM A216, A351, and industry standards.

Engineered for precise flow control and reliable isolation with corrosion-resistant design.
Globe valves manage water flow in a pipeline through a movable plug/disc-type element and a stationary ring seat in a spherical body. The plug is connected to a stem that operates through a screw action.
Here is a quick-reference globe valve diagram for easy understanding:
There are three basic globe valve body designs: Tee, Angle, and Wye. Each design has unique characteristics, advantages, and applications.
Primarily, when people talk about the type of globe valve, they mean the body style.
The classic and most common globe valve design. The seat is placed horizontally, and the stem moves vertically to the flow.
The ends are set at a 90° angle, requiring fluid to make a single turn. Useful for flows that pulse or surge.
The seat and stem are set at a 45° angle, providing a straighter flow path and reducing pressure drop.
Globe valves and Gate valves are among the most common valves used in industrial plants. Both are engineered to keep systems running efficiently and safely, but their unique designs make them suitable for different applications.
| Aspect | Globe Valve | Gate Valve |
|---|---|---|
| Design | Parts are located inside the cavity, with a rising stem that allows flow changes but also contributes to higher pressure drop. | Simpler construction, most internal components are in the upper part of the body. Provides little pressure drop when open. |
| Flow Control | Excellent for throttling and regulating flow. | Designed mainly for on/off service, not ideal for throttling. |
| Pressure Drop | Higher pressure drop due to changes in flow direction. | Low pressure drop when fully open, straight-through flow path. |
| Applications | Used in applications requiring frequent operation and precise flow control. | Common in pipelines for isolation service, where the valve is fully open or closed. |
| Operation Speed | Slower operation due to shorter stem travel. | Faster operation with longer stem travel to open/close fully. |
| Durability | Better suited for throttling but may wear faster under high-pressure drops. | Longer service life when used in fully open or closed positions. |
| Functions | Primarily used as a control valve. | Designed for media isolation, not for flow control. |
| Working | The disc moves parallel to media flow, requiring minimal lift for full flow. | The disc moves at a right angle to the flow, providing either full flow or zero flow. |
