If you use different manufacturers for your controller and valves, what should you do?

• A. Use only one brand
• B. Assume compatibility
• C. Replace all components
• D. Double check compatibility with the manufacturer

Answer: (D)

When mixing components from different manufacturers, you must verify compatibility with the controller manufacturer. Different brands often use different electrical signaling, voltages, and connector standards, as well as varying pilot pressures and mounting interfaces. Without checking, the system may not operate correctly, could damage parts, or void warranties. The right step is to consult the manufacturers’ compatibility guidance, review official documentation for supported pairings, and use any recommended adapters or clearly designated compatible models. This ensures the controller can properly drive the valves and that electrical, hydraulic, and mechanical specs align. Using only one brand isn’t a necessity if a compatible pairing can be confirmed, while assuming compatibility or replacing all components unnecessarily can lead to preventable problems.
