FAQ

Common questions from OEMs and plant operators.

Are you the actuator manufacturer, not a trader?
Yes. MTD Actuator is a manufacturer based in Ningbo, China, designing, assembling and testing electric actuators and motorized valves in-house.
Are your valves resistant to seawater corrosion?
Yes. Our SS316 wetted parts are built for seawater and high-chloride environments. Material options can be confirmed against your water chemistry.
Can actuators handle high-pressure RO duty?
Yes. We supply high-pressure actuator-valve packages for RO feed and train isolation applications.
Do you support OEM/ODM and private label?
Yes. We offer OEM/ODM programs including custom voltage, mounting, branding, logo, and packaging on volume orders.
What is the minimum order quantity and lead time?
Samples and small trial orders are welcome. Standard stock ships quickly; production MOQ and lead time are quoted per specification.
