How to Choose the Right Butterfly Valve

Selecting the appropriate butterfly valve involves considering several factors:

• Application Requirements: Determine if the valve will be used for isolation, control, or regulation purposes.
• Media Characteristics: Consider the temperature, pressure, and chemical properties of the fluid being handled.
• Size and Flow Requirements: Calculate the required flow rate and select a valve with appropriate Cv value.
• Pressure Rating: Ensure the valve can withstand the maximum system pressure with an adequate safety margin.
• Temperature Range: Verify that all valve components are suitable for the operating temperature range.
• Actuation Method: Decide between manual operation or automated control with pneumatic, electric, or hydraulic actuators.
• Installation Space: Consider the available space and choose between wafer, lug, or flanged designs accordingly.

Maintenance and Troubleshooting

Proper maintenance ensures the longevity and reliable performance of butterfly valves:

• Regular inspection of seals and seats for signs of wear or damage
• Lubrication of moving parts according to manufacturer recommendations
• Checking for proper alignment and adjustment of actuators
• Cleaning of valve internals to prevent buildup of deposits
• Replacement of worn components before failure occurs

Common issues and solutions:

• Leakage: Usually caused by worn seats, improper alignment, or damaged sealing surfaces. Replacement of seals or valve refurbishment may be required.
• Difficult Operation: May indicate issues with the stem, bearings, or actuator. Proper lubrication or component replacement can resolve this.
• Incomplete Closure: Often due to debris trapped between the disc and seat or actuator adjustment problems. Cleaning and recalibration are typically effective solutions.
