Choosing the right type of stop valve: Considerations for pipeline layout and fluid flow

In complex industrial pipeline systems, choosing the right type of globe valve is crucial to ensure smooth and safe flow of fluid. As a key component for controlling the on and off of fluid, the type of globe valve needs to be closely combined with the pipeline layout and fluid flow direction for comprehensive consideration. This article will explore in depth the application scenarios of straight-through globe valves and angle globe valves, and how they adapt to different pipeline needs.

Straight-through globe valve: the best choice for straight pipelines
Straight-through globe valves, as the name suggests, are designed to allow fluids to maintain a straight flow when passing through the valve, reducing flow resistance and pressure loss. The inlet and outlet channels of this valve are on the same straight line, with a compact structure and easy installation, making it particularly suitable for straight pipeline systems. In situations where there is no need to change the flow direction of the fluid or only simple on and off is required, straight-through globe valves are undoubtedly an ideal choice.

Its advantages are:
Low flow resistance: The straight-line flow design reduces the disturbance and energy loss of the fluid in the valve.

Easy installation: Standardized flange connections or threaded connections make the installation process fast and efficient.

Easy maintenance: Simple structure, easy to disassemble and repair.
Angle globe valve: a tool for changing the flow direction of fluids
In contrast, the inlet and outlet channels of angle globe valves are at a certain angle (usually 90 degrees or 45 degrees). This design enables it to play an important role in situations where the flow direction of fluids needs to be changed. Angle globe valves can not only control the on and off of fluids, but also flexibly adjust the direction of fluids in a limited space to meet the special needs of pipeline layout.

Its application scenarios include but are not limited to:
Compact equipment: In situations where the equipment layout is compact and the space is limited, angle globe valves can make full use of space, reduce pipeline bending, and reduce installation difficulty.
Change flow direction: In pipeline systems where the flow direction of fluids needs to be changed, such as branch pipelines, steering pipelines, etc., angle globe valves can provide smooth fluid paths.
Specific process requirements: Some process flows require specific fluid flow directions, and angle globe valves can meet these special requirements to ensure the stability and efficiency of the process.
Selection principles and precautions
When selecting the type of globe valve, in addition to considering the pipeline layout and fluid flow direction, you should also pay attention to the following points:

Medium characteristics: Select appropriate materials and sealing structures based on factors such as medium temperature, pressure, and corrosiveness.
Operation requirements: Consider the operation mode (manual, electric, pneumatic, etc.) and the requirements of the operating torque.
Safety and reliability: Ensure that the selected valve meets the relevant standards and specifications and has good sealing performance and durability.
Cost-effectiveness: Consider the price, maintenance cost and long-term operation benefits of the valve and choose a product with high cost performance.
Selecting the appropriate globe valve type according to the pipeline layout and fluid flow direction is the key to ensuring the safe and efficient operation of the pipeline system. Both straight-through globe valves and angle globe valves have their unique advantages and application scenarios. In practical applications, comprehensive considerations should be made according to the specific situation to select the most suitable valve type.
