- Can dual AF actuators on the same shaft be wired parallel?
- No, dual AF actuators on the same shaft should NOT be wired parallel.

- No, the new-generation SR actuators have removed primary and secondary capabilities, so the AFB24-SR cannot replace the older dual-mounted AF24-SR.
- Is there a difference in functionality between the AFB24-MFT and AFB24-MFT-X1?
- No, there is no difference in functionality between these two models. The only difference is that the AFB24-MFT-X1 has a linkage and is designed to pair with a valve.

- Do Fire and Smoke (FS) actuators come with plenum-rated cables?
- No, they do not.
- Do Fire and Smoke (FS) actuators require maintenance?
- No, they never require maintenance.
- Can Fire and Smoke (FS) actuators be mounted on valves?
- No, they should never be mounted on valves.
- What is the rating of Fire and Smoke (FS) actuators?
- They are NEMA 1/IP40 rated.
- Are Belimo flow meters rated for use in wastewater treatment applications?
- No, they are not rated for use in wastewater treatment applications.
- Are Belimo flow meters rated for use in potable water?
- No, they are not rated for potable water.
- Are Belimo flow meters factory calibrated?
- They are wet-calibrated from the factory to ensure accuracy.
- Does Belimo have universal butterfly valve retrofit kits?
- No, we do not.
- Does Belimo have universal globe valve retrofit kits?
- Yes, we do.
- Can the Belimo UGVL linkage be used on both new and old-style Belimo globe valves?
- No, it cannot.
- Should an SGVL linkage be used to retrofit current Belimo globe valves?
- No, it should not be used.
- Do FGVL linkages work on Belimo flanged globe valves?
- Yes, they do.
- Does Belimo have universal ball valve retrofit kits?
- No, we do not.
- Can universal linkages for Belimo linear valve actuators be purchased separately?
- Yes, they can.
- How should steam valves be piped?
- Steam valves should always be piped in horizontal piping.
- What does Cv mean?
- Cv is a valve’s flow rating, indicating how many gallons per minute (GPM) of water at 60°F can flow through the valve with a 1 psi pressure drop.
- Can the B port on a three-way valve be capped to convert it to a two-way valve?
- No, a three-way valve cannot be capped to convert it to a two-way valve.
- Should the characterizing disc in a Belimo CCV be removed in the field?
- No, the disc is not designed to be removed at all.
