A Quick Buyer's Checklist for Butterfly Valves with Actuators (2025)

With so many options on the market, varying in materials, actuation types, pressure ratings and control mechanisms, it’s easy to get overwhelmed when it comes to butterfly valves with actuators. 

The wrong choice can lead to inefficiencies, downtime or even safety risks both in the upgrading or selecting components for new installations. 

To help you make better decisions, this quick checklist breaks down everything you need to consider before you buy - from compatibility and durability to automation and maintenance.

The 6 Buyer’s checklist for butterfly valves with actuators

Know Your Application

The first step in selecting the right butterfly valve with an actuator is understanding your specific application requirements.

Different fluids demand different materials and seal types. See whether your medium is corrosive if it contains solids or particulates, its temperature range and whether it's a gas, liquid or slurry.

Various industries have unique requirements as well. Food and beverage applications need sanitary designs and food-grade materials, while chemical processing requires excellent chemical resistance.

So, define precisely what function the butterfly valve will serve for your plant. Taking time to clearly understand these fundamental requirements will narrow your options considerably.

The materials used in your butterfly valve construction can impact the performance and longevity of the same

For body materials, options range from economical cast iron with limited chemical resistance to ductile iron with higher strength and pressure ratings.

Carbon steel works well for high-temperature applications and stainless steel offers excellent corrosion resistance. Also, the PVC/CPVC serves non-metallic applications with specific chemicals.

Disc materials include stainless steel as a standard for many applications, aluminum bronze for seawater applications, nylon-coated for abrasive media and PTFE-coated for enhanced chemical resistance.

Seat and seal materials are equally important. EPDM works well for water and steam applications, while NBR (Nitrile) is excellent for petroleum products.

PTFE offers outstanding chemical resistance, silicone handles high-temperature applications and FKM (Viton) provides combined chemical and temperature resistance.

As we mentioned earlier, each serves a different thing. So, select materials based on compatibility with your specific medium, operating temperatures and pressure requirements.

Actuator Type

When it comes to the actuator, you'd have two options:

  • Pneumatic actuator
  • Electric actuator

The choice between these two impacts the valve performance.

Pneumatic actuators offer faster operating speeds and are intrinsically safe for hazardous environments. They generally have a lower initial cost and simpler maintenance but require compressed air infrastructure and may need accessories like solenoid valves and positioners.

Electric actuators, on the other hand, provide precise positioning for modulating control and don't need compressed air. They offer advanced feedback and communication options with higher energy efficiency, though they come with a higher initial cost and more complex maintenance.

If you're confused between these two, consider factors such as power availability, control precision requirements and operational environment when selecting your actuator type.

Sizing & Pressure Rating

Proper sizing is critical for optimal performance. Your consideration should include flow rate requirements, pressure drop limitations, line size compatibility and space constraints for installation.

Undersized valves restrict flow and create excessive pressure drops and oversized ones may lead to poor control, water hammer and unnecessary expense.

For pressure ratings, ensure the valve's rating exceeds your system's maximum working pressure. Consider both working pressure and test pressure, and account for pressure spikes and surges.

Also, don't forget to verify temperature effects on pressure ratings, as most valve pressure capabilities decrease at higher temperatures.

Taking the time to correctly calculate these parameters will prevent most common valve-related issues.

Maintenance & Support 

Long-term reliability depends on both the product quality and available support.

Consider spare parts availability, technical support and documentation, warranty terms and conditions, service network accessibility and training options for maintenance staff.

For specialized applications or critical processes, working with reputable Butterfly Valves with Actuators Suppliers in Dubai can provide peace of mind with local expertise and quick response times. A local supplier often means faster service and reduced downtime when issues arise.

Final Checklist

To ensure you make the best decision, verify these essential points before placing your order:

  • Ensure valve size and pressure rating match system requirements.
  • Verify materials are compatible with the process fluid and operating conditions.
  • Confirm the actuator type suits your control requirements and available power source.
  • Check that torque requirements have been properly calculated for reliable operation.
  • Validate that the valve has all necessary certifications and compliance with relevant standards.
  • Ensure installation space accommodates the entire valve-actuator assembly.
  • Confirm the delivery timeline meets your project schedule requirements.

Taking the time to review these critical checkpoints before finalizing your purchase can prevent costly mistakes and ensure you select a butterfly valve with an actuator that delivers reliable performance for your specific application needs.
