Product Selection Differences for Bare Shaft Butterfly Valves

When selecting Bare Shaft Butterfly Valves, there are several key differences to consider:

1. Size and Application: Consider the size range and specific application requirements of the valve. Ensure that the valve size matches the piping system and flow requirements for optimal performance.

2. Valve Material: Choose the appropriate material based on factors such as the type of fluid being handled, temperature, pressure, and corrosiveness. Common materials include stainless steel, carbon steel, and PVC.

3. Design Type: Bare shaft butterfly valves come in various design types, such as concentric, double offset, and triple offset. Each design offers different performance characteristics in terms of sealing, pressure rating, and flow control.

4. Sealing Technology: Consider the sealing mechanism used in the valve, such as resilient or metal seals. Resilient seals (rubber or PTFE) provide tight shut-off but may have limitations in terms of temperature and chemical compatibility, while metal seals offer higher temperature and pressure capabilities.

5. Operation and Actuation: Bare shaft valves require external actuation equipment for operation. Consider the type of actuator (manual, electric, pneumatic, hydraulic) required for your application and ensure compatibility with the valve.

6. Performance and Standards: Look for valves that meet industry standards such as API, ANSI, or ISO to ensure quality, reliability, and compliance with regulations.

7. Maintenance and Service: Consider ease of maintenance, availability of spare parts, and the reputation of the manufacturer for customer support and service.

By considering these factors, you can select the most suitable Bare Shaft Butterfly Valve for your specific application needs.
