Buying Guide: Key Purchase Considerations
When choosing an electric actuator for butterfly valves, the following factors help align selection with your application needs:
- Valve size and mounting: Confirm the actuator’s torque rating and mounting type (wafer vs. lug) to ensure a secure fit and reliable actuation for your valve size and piping layout.
- Voltage and control: Most options here use 24V DC or 24V AC. Consider compatibility with existing controls, safety standards, and energy efficiency goals.
- Media and temperature: EPDM seals and ductile iron bodies provide resilience in water and air services and broad temperature ranges. For harsher media, verify chemical resistance and gasket compatibility.
- Durability and environment: Industrial environments demand rugged housings and corrosion resistance. Pool/spa actuators add weatherproof and UV-resistant features for outdoor installations.
- Ease of installation: Tool-free setup, cam adjustments, and plug-and-play connectors reduce commissioning time and technician requirements.
- Maintenance and serviceability: Look for predictable torque, repeatable valve positions, and clear indicators that support proactive maintenance.
- Future-proofing: If you anticipate valve upgrades or automation expansion, select actuators with broad compatibility and adjustable travel/angles.
For industrial water and air applications, prioritize durability, precise control, and robust sealing. For pool and spa systems, emphasize plug-and-play compatibility, weatherproofing, and compatibility with common control panels. Across all uses, ensure that the actuator torque matches the valve’s opening torque to prevent under- or over-travel and to maintain reliable sealing under pressure.
