A few years ago nobody trusted Chinese modulating actuators. Now half the new water treatment and chemical dosing skids have Peckwomy 4–20 mA units on the butterfly or globe valves. They hold position within 1–2%, cost a third of the imported ones, and the feedback actually works. Many plants tested one, then replaced all their old ones with Peckwomy because the price difference paid for itself in months.

• True 4–20 mA input and output – real position feedback
• 0.5–1% deadband – good enough for most loops
• Auto-calibration button – press once, done
• Fail-freeze or fail-open option
• Works with ball, butterfly, and plug valves
• LED status lights – green running, red fault

• Water flow control valves
• Cooling water temperature loops
• Chemical dosing lines
• Air damper control

Q: Does the feedback really work?
A: Yes – 4–20 mA output follows valve position accurately.

Q: Can I adjust deadband?
A: Yes – from the front panel or with the little remote.
