GYLDT duckbill valve model will change [2014-10-08]

From the first duckbill valve was made twenty years ago, duckbill valves were named by Chinese system of valves. For example, XH81A-the “X” is rubber, “H” is check, “81” means the connection is clamp, “A” is the type. Until a customer asked us, what do you mean by XH81A? So we explained it was a Chinese method to name the valves, and our customer had to explain to his customer, it’s an inconvenience way to make things clear. And in another hand, engineers of GYLDT had improved all spool type duckbill valves to a curved bill, as experience showed curved bill design is better sealed; the straight bill design is only for part of the mould made duckbill valve, it has smooth surface and as good seal as curved bill design, the only disadvantage is the size only from DN20 to DN300. New model of duckbill valves will be: 1. RV-FMO: Rubber valve, flange connection, mould type, out installation. 2. RV-CMO: Rubber valve, clamp connection, mould type, out installation. 3. RV-FSO: Rubber valve, flange connection, spool type, out installation. 4. RV-FSI: Rubber valve, flange connection, spool type, inner installation. 5. RV-CSO: Rubber valve, clamp connection, spool type, out installation. 6. RV-CSI: Rubber valve, clamp connection, spool type, inner installation. 7. RV-FSH: Rubber valve, flange connection, spool type, housed inner installation. 8. RV-C: Rubber valve, customizing items.
