Product Advantage

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.

Our valve seat use imported nature rubber, with more than 50% of rubber inside. The seat has a good elasticity property, with long service life. It can be open and close more than 10,000 times with no damage for the seat.

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.

Handle of the valve use ductile iron, is anti-corrosion than regular handle. Spring and pin use ss304 material. Handle part use semicircle structure, with good touch feeling.

Butterfly valve pin use modulation type, high strength, wear-resisting and safe connection.

ZFA Valve body use solid valve body, so the weight is higher than regular type.

The valve adopt epoxy powder painting process, thickness of tht powder is 250um at least. Valve body should be heating 3 hours under 200℃, powder should be solidify for 2 hours under 180℃.

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.
