FAQ

Common questions from HVAC contractors and OEM buyers.

Are you the actuator manufacturer, not a trader?
Yes. MTD Actuator is a manufacturer based in Ningbo, China. We design, assemble and test electric actuators and motorized valves in-house — with own production lines for both actuators and valve bodies.
What torque range and valve sizes do you cover?
Standard electric actuators cover 10–2000Nm, matched with ball, butterfly and 3-way valves from DN15 to DN300. Larger custom packages are available on request.
Can I get 24V modulating control with 0–10V signal?
Yes. We supply 24V AC/DC and 220V actuators with floating, 0–10V proportional or PWM control, with feedback signal options for BMS integration.
Do you support OEM/ODM and private label?
Yes. We offer OEM/ODM programs including custom voltage, mounting, branding, logo, and packaging for volume orders. Contact us with your drawing or specification.
What is the minimum order quantity and lead time?
Samples and small trial orders are welcome. Standard stock items ship quickly; production MOQ and lead time are quoted per specification — request a quote for details.
