📝 Product Description
A globe valve is an instrument used to stop and/or control the flow of fluids in a pipeline. It works by halting the flow of a fluid through a pipe. The name globe comes about due to the valve's cylindrical shape. There are usually two halves of the body within the globe valve that are separated by an internal baffle.
Key Characteristics:
- A curved valve body
- A gap in the centre of the pipe with a seat that a circular plug can sit in firmly
- A handle and stem that is twisted to raise or lower the plug
- A bonnet and packing to prevent leakage
- Designed for one-way fluid flow
Advantages:
- Good shutoff capability
- Moderate to good valve throttling capability
- Shorter stroke compared to a gate valve
- Easy to machine or resurface the seats
- Can be used as a stop-check valve
- Long life performance with small friction between sealing faces
🔍 Working Principle
The disc inside the valve is movable whereas the seat is stationary in a spherical body. The disc moves up and down according to the actuation of the wheel. When the wheel is moved manually or via an actuator, the disc rises or falls. To stop the flow completely, the disc is fully seated on the seat ring. Throttling is achieved by adjusting the position of the disc.
🔧 Main Components
Body & Seat Ring
The body is the main structure containing all internal parts. The seat ring provides a stable and replaceable shutoff surface, sealing the space between the disk and bonnet.
Bonnet & Stem
The bonnet connects to the body for a leak-proof closure (bolted, screw-in, or union types). The stem connects the disk to the handwheel or actuator to transmit actuation force.
Plug (Disk)
The plug acts as a physical barrier moving perpendicular to the seat. Available in composite, ball, and needle types for different pressure and temperature needs.
❓ Frequently Asked Questions
What is a globe valve used for?
A globe valve is primarily used to stop, start, or regulate the flow of fluids in a pipeline, offering excellent throttling and shutoff capabilities.
Can globe valves handle high-pressure applications?
Yes, these valves are designed to handle various pressure ratings from ASME 150# up to 2500#, making them suitable for demanding industrial environments.
What materials are used for construction?
The valves are typically manufactured using high-quality Carbon Steel and Stainless Steel to ensure durability and resistance to corrosion.
How does a globe valve differ from a gate valve?
Globe valves have a shorter stem stroke compared to gate valves and are much better suited for throttling flow, whereas gate valves are primarily for full on/off service.
What standards do your globe valves comply with?
Our globe valves are designed and manufactured in accordance with international standards including DIN, GB, ANSI, BSW, and JIS.
Is it possible to customize the coating or design?
Yes, we offer OEM and ODM services, allowing for customized coatings and special material requirements to meet specific industrial needs.
