Everything You Need to Know
 

 

How to select the right type of check valve for my system?

Key considerations: media, pressure, flow rate, installation space, and backflow prevention requirements. Spring type suits frequent on-off cycles and limited space; Swing type suits high flow, horizontal pipes; Wafer type saves space. Feel free to share your parameters for our engineer's recommendation.

What is the Minimum Order Quantity (MOQ) for customization?

Standard products have low MOQ. For custom specs (special size, logo engraving, special packaging), the MOQ depends on process complexity. We strive to meet buyers of various scales.
