Industrial Valve application topic: How to correctly select
gate valves, water stop valves,
butterfly valves and
ball valves
June 11, 2025 As my country's industrial 4.0 process accelerates, the selection of valves as core components of fluid control has received increasing attention. This newspaper specially invited fluid control experts to analyze the key points of using four types of mainstream valves.
Structural features: wedge-shaped gate is used to cut off fluid vertically
Applicable scenarios: fully open/closed conditions such as petroleum, water supply and drainage
Key points for use: not suitable for throttling control, installation must ensure that the valve stem is vertical
2. Stop valve (stop valve): precise flow control expert
Core advantages: small wear on the sealing surface and high adjustment accuracy
Typical applications: steam system, high-pressure pipeline
Operation specification: must follow the "low in and high out" installation principle
Innovative design: the disc-type opening and closing parts can be operated by rotating 90°
Energy-saving characteristics: head loss is only 1/3 of the gate valve
Maintenance tips: rubber sealing rings need to be checked and replaced regularly
4.
Ball Valve: reliable guarantee for emergency cut-off
Response speed: 1/4 turn can achieve fast opening and closing
Pressure resistance performance: can reach Class1500 high-pressure standard
Selection suggestion: V-type ball valve is particularly suitable for slurry media
Industry trend: the valve market size is expected to exceed 8 billion yuan in 2025, and electric actuators with Internet of Things functions are becoming the standard of the new generation of valves.
