Globe Control Valve

About Globe Control Valve

Globe Control Valve

A globe control valve is a type of linear motion valve that uses a movable plug or disc and a stationary seat to regulate the flow of fluids in pipelines

The valve body, usually spherical or constructed with internal partitions, guides fluid flow and supports the valves components. The disc moves perpendicular to the seat, allowing precise modulation of flow rate, while the stem connects the disc to an actuator or handwheel

This design enables excellent sealing, accurate throttling, and durability in systems with variable pressure and temperature conditions

Key Components

• Valve Body: Houses internal components and fluid flow path. Variants include straight, Y-pattern, and angle-shaped bodies 

• Bonnet: Covers the body, providing a leak-proof seal; types include bolted, welded, flanged, union ring, and pressure-seal 

• Stem: Transfers actuator motion to the disc; can be threaded or smooth for automated systems 

• Disc/Plug: Main closure element; types include plug disc, composition disc, and ball disc, optimized for flow regulation or shutoff 

• Seat Ring: Stationary ring providing guiding and sealing surface for the disc 

• Packing and Gaskets: Prevent leakage along the stem and between body components 

Types of Globe Valves

• T-pattern (or Z-pattern): Standard design; good for throttling but higher pressure drop 

• Y-pattern (Oblique): Angled seat reduces flow resistance, ideal for low-pressure loss and high flow applications 

• Angle pattern: 90 inlet/outlet for directional changes; reduces pipe fitting needs and manages pulsating flow 

• Single-seated, Double-seated, Three-way diverting: Variations for different industrial flow capacities and mixing/diverting operations 

Actuation Methods

Globe valves can be manual or automated, depending on process control requirements

• Manual Handwheel: Common for small or low-pressure systems.

• Pneumatic Actuators: Fast response using compressed air.

• Hydraulic Actuators: High force for heavy-duty applications.

• Electric / Electro-Hydraulic Actuators: Precise, automated control for complex systems.

Applications

Globe control valves are widely used in industries requiring accurate flow regulation and safety-critical operations such as

• Oil and Gas: controlling crude oil, natural gas, refined products.

• Petrochemical and Chemical Processing: managing corrosive or hazardous fluids.

• Power Generation: regulating steam, water, and coolant flow in turbines and boilers.

• Water and Wastewater Treatment: flow and chemical dosing control.

• Mixing and Diverting Fluids: three-way valves split or combine flow efficiently.
