We received a enquiry about duckbill valve, the working pressure as below:
We quote it and told customer that “the duckbill valve has been used for air, but the flow is not exact. Because we do not produce the valves under the working pressure, we will produce it better to meet your requirements”. Then the customer accept it and send us the PO. Told us if duckbill valves can work it will be also install in other projects. We produce the goods and send it to the customer ASAP. The customer told us duckbill valve can work, we will discuss other projects later. Believe that there will be more chance to cooperate with this customer.
