Steam pipelines are critical components in various industries, including power generation, chemical processing, and HVAC systems. Selecting the appropriate valve for steam applications is essential to ensure safety, efficiency, and longevity of the system. Yuanda Valve Group offers a range of valves suitable for steam pipelines, each designed to meet specific operational requirements.

Valve Selection Criteria for Steam Pipelines

When choosing valves for steam pipelines, consider the following factors:

• Temperature and Pressure Ratings: Ensure the valve can withstand the operating conditions of the steam system.

• Material Compatibility: Select materials resistant to high temperatures and potential corrosive effects of steam.

• Functionality: Determine whether the valve is needed for isolation, flow regulation, or backflow prevention.

• Size and Pressure Class: Match the valve size and pressure class to the pipeline specifications.

Recommended Valve Types for Steam Applications

1. Gate Valves

• Function: Isolation (fully open or fully closed)

• Advantages:

• Excellent sealing performance

• Low flow resistance when fully open

• Applications: Mainline isolation in high-pressure steam lines

• Materials: Cast steel, forged steel, stainless steel

• Actuation: Manual handwheel or electric actuator

Yuanda's gate valves are designed to provide reliable isolation in steam systems, ensuring minimal leakage and efficient operation.

2. Globe Valves

• Function: Flow regulation and throttling

• Advantages:

• Precise flow control

• Can handle high temperature and pressure

• Applications: Control stations, temperature regulation, or bypass lines

• Materials: Cast steel, forged steel, stainless steel trim

• Actuation: Manual handwheel, pneumatic, or electric actuator

Yuanda's globe valves are engineered for accurate flow control in steam systems, allowing for precise adjustments to meet operational needs.

3. Ball Valves

• Function: Quick shut-off or blowdown

• Advantages:

• Fast operation

• Compact design

• Applications: Blowdown lines, drain systems, and isolation points

• Materials: Stainless steel or carbon steel with high-temperature seals

• Actuation: Manual lever, pneumatic actuator, or electric actuator

Yuanda's ball valves are suitable for applications requiring rapid opening and closing, ensuring quick response times in steam systems.

4. Check Valves

• Function: Prevent backflow to protect equipment like boilers or traps

• Advantages:

• Automatic operation

• Protects boilers and steam traps

• Applications: Condensate lines, boiler protection

• Materials: Cast or forged steel, stainless steel

• Types: Swing check valve (horizontal lines), lift check valve (vertical systems)

Yuanda's check valves are designed to prevent reverse flow, safeguarding critical components in steam systems.

5. Butterfly Valves

• Function: On-off control in large, low-pressure steam lines

• Advantages:

• Cost-effective

• Easy to install and maintain

• Applications: Large low-pressure steam ducts, non-critical systems

• Materials: Cast steel or ductile iron body, stainless steel disc, graphite seat

• Actuation: Manual gear, pneumatic, or electric actuator

Yuanda's butterfly valves are ideal for applications where space and cost considerations are paramount, providing reliable on-off control in steam systems.
