10 Questions You Should Know about the H920 Hilton Wafer-Swing Check Valve

1. What is the H920 Hilton Wafer-Swing Check Valve?

The H920 Hilton Wafer-Swing Check Valve is an advanced valve designed to permit fluid flow in one direction while preventing backflow. Its wafer-style design allows for easier installation between flanges, making it a preferred choice in various applications such as waterworks, HVAC, and industrial systems.

2. What materials are used in the H920 valve?

This valve is typically constructed from high-quality materials such as stainless steel, cast iron, or carbon steel. Each material is chosen based on the specific requirements of the application, including temperature, pressure, and fluid compatibility.

3. What are the key features of the H920 Hilton Wafer-Swing Check Valve?

• Compact Design: The wafer-like structure allows for space-efficient installations between flanges.
• Bi-Directional Flow: Although it primarily functions to prevent backflow, it can be oriented for bi-directional flow in certain configurations.
• Minimal Maintenance: The valve is designed to require minimal upkeep, providing long-lasting service.
• High Durability: Manufactured to endure high pressure and temperature, making it suitable for various industrial applications.

4. In which applications is the H920 valve commonly used?

The H920 is popular in applications like:

• Water supply and waste management systems
• Pumping stations
• Chemical processing facilities
• HVAC systems

5. How does the wafer-swing design function?

The wafer-swing design utilizes a swing disc that pivots on a hinge, allowing for the valve to open during forward flow. When flow ceases or reverses, the disc swings back against the seat, effectively sealing the valve and preventing backflow.

6. What are the installation requirements for the H920 valve?

Installation is straightforward but should follow these guidelines:

• Ensure proper alignment between the valve and flanges
• Use appropriate gaskets to ensure a leak-free seal
• Follow torque specifications for bolting to prevent damaging the valve

7. What are the maintenance requirements for the H920 valve?

Regular inspections are recommended to check for wear or corrosion. The valve typically requires minimal maintenance, but components like seals may need replacement depending on usage and environment.

8. What are the benefits of using the H920 Hilton Wafer-Swing Check Valve?

• Enhances system efficiency by preventing backflow
• Saves installation space due to its compact design
• Reduces operating costs with low maintenance needs
• Highly adaptable to various industrial environments

9. Are there any limitations of the H920 valve?

While the H920 valve is versatile, there are limitations to consider, such as:

• Not suitable for use under vacuum conditions
• Performance may be affected in low-flow scenarios

10. How do I select the right H920 valve for my application?

Choosing the right valve involves assessing the flow characteristics, pressure, temperature, and compatibility with the fluid. Consulting with a qualified engineer or supplier can help you make the best choice for your specific needs.
