Product Q&A

Q:What is the working principle of the double-layer flap valve?

The valve uses upper and lower layers that switch at different times. The upper valve opens via mechanical transmission and closes by balance weight, followed by the lower valve. This keeps the middle closed to prevent air turbulence and acts as a gas lock for powdered material conveying.

Q:What materials are available for the valve body?

You can choose from stainless steel (SS304, SS304L, SS316, 316L, SS836L) or carbon steel based on actual needs. Polishing accuracy can reach 300# for food-grade applications.

Q:What drive methods are supported?

The valve supports pneumatic, electric, and manual drive methods. Motor power ranges from 0.55kw to 6kw depending on the model.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 1 set.

Q:Can the product be customized?

Yes, we offer OEM and ODM services. Customization options include samples, designs, full customization, minor customization, and flexible customization. Capacity and flange sizes can be adjusted.
