FAQs – DN20 Fan Coil Motorized Valve
Q1: Do you supply both 2-way and 3-way motorized valves?
Yes. A 2-way valve controls flow in one direction, while a 3-way valve is designed for mixing or diverting flow between two channels.
Q2: Can the motorized valves be customized for international OEM projects?
Yes, we provide OEM & ODM customization, including special voltage ranges, housing design, branding, and material selection.
Q3: What is your typical delivery time for valve orders?
For bulk orders, the lead time is usually 2–4 weeks, depending on order volume and customization needs. We also stock popular models for quicker delivery.
Q4: Can I get samples before placing a bulk order?
Yes, we encourage international customers to test samples to ensure suitability before mass purchasing.
