Globe valve

A globe valve moves a disc or plug relative to a seat to control the flow passage. Straight, angle and Y-pattern bodies have different installation envelopes and flow paths.

Globe valves: compare construction, connections and application requirements. Confirm materials, operating conditions and complete-valve ratings for your project.

Globe valves — Selection and installation guide

Design and application checks

A globe valve moves a disc or plug relative to a seat to control the flow passage. Straight, angle and Y-pattern bodies have different installation envelopes and flow paths.

Follow the marked flow direction and the product instructions; do not apply one universal flow direction to every globe valve. For regulating service, confirm trim characteristic, differential pressure, required flow and cavitation or noise limits.

What should I provide for a quotation?

Provide the fluid and composition, solids content, normal and design pressure and temperature, DN or NPS, connection standard, installation orientation, operating duty and required inspection documents. State any corrosion, vacuum, fire-safety or emissions requirements separately.

How do I confirm the pressure and temperature rating?

Use the approved data sheet, nameplate and pressure–temperature limits for the complete valve, including its seat, lining and seals. PN, ASME Class and JIS K are different designation systems, not a fixed numerical conversion. A shared nominal size does not establish flange interchangeability.

What must be checked before installation?

Compare the face-to-face dimension, flange drilling and facing, pipe bore, flow direction and maintenance clearance with the approved drawing. Clean and isolate the pipeline, release pressure and follow the product installation instructions. Do not use flange bolts to pull misaligned pipework into position.

Stop valve

01 Why are stop valves suitable for throttling, while gate valves are not?
The core concept can be summed up in one sentence: The stop valve is like a faucet, allowing you to control the flow of water precisely by adjusting the opening degree; the gate valve is like a door, either fully open or fully closed; when it is partially open or closed, the water flow will "scrape" and damage the sealing surface of the gate plate.
The figure above has already shown the structural comparison between the two. The flow channel of the stop valve on the left is S-shaped (the fluid changes direction, which is itself a throttling principle), while the flow channel of the gate valve on the right is straight-through (the fluid does not turn, and the gate plate is suspended in the middle and is subject to erosion and vibration).
Selection rule: Use a stop valve for throttling and regulating; use a gate valve for full opening and full closure.
02 How to evaluate valve manufacturers?
The product's execution standards, pressure ratings and material ranges, valve body and internal component traceability, pressure and sealing test documents, flow direction and installation requirements, similar medium experience, and after-sales responsibilities should all be verified. The supplier should also provide a written confirmation of the selection based on the medium, temperature, pressure difference, diameter and regulation requirements.
03 What are the characteristics of stop valves and in which situations are they applicable?
The stop valve achieves cutting or regulation by the movement of the valve disc along the axis of the valve seat. It usually has good throttling characteristics, but the flow channel turns will result in higher pressure loss compared to the straight-through type valve. It is commonly used in steam, process media and pipelines requiring certain flow regulation; the specific structure, materials and flow direction should be determined according to the working conditions.
