OEM PTFE Seat Wafer Type Butterfly Valve Manufacturer, Exporter
Product Description
Our valve connection standards include DIN, ASME, JIS, GOST, BS etc. It’s easy for customers to choose the suitable valve, help our customers reduce their stock.
Our valve has standard thickness according to GB26640, makes it capable of holding high pressure when needed.
The valve body use GGG50 material, has higher mechanical property, rate of spheroidization more than 4 class, makes the ductility of the material more than 10 percent. Compare to regular cast iron, it can suffer higher pressure.
Each valve should be cleaned by ultra-sonic cleaning machine, in case of contaminant left inside, guarantee the cleaning of the valve, in case of pollution to the pipeline.
The valve body use high adhesive force epoxy resin powder, helps it adhere to the body after melting.
Marker Plate located on body side of the valve, easy to watch after installation. Material of the plate is SS304, with laser marking. We use stainless steel rivet to fix it, makes it cleaning and tighting.
Non-pin stem design adopt anti-blowout structure, the valve stem adopt double jump ring, not only can compensate the error in installation, but also can stop the stem being blow off.
Each product of ZFA has material report for the main parts of the valve. ZFA Valve body use solid valve body, so the weight is higher than regular type.
Body Test: The valve body test use 1.5 times pressure than standard pressure. The test should be done after installation, the valve disc is half close, called body pressure test. The valve seat use 1.1 times pressure than standard pressure.
Special Test: According to customer’s requirement, we can do any test you need.
