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.
Non-pin stem design adopts 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.
The valve adopts epoxy powder painting process, thickness of the powder is 250um at least. Valve body should be heating 3 hours under 200℃, powder should be solidified for 2 hours under 180℃.
After natural cooling, the adhesive of the powder is higher than regular type, guarantee there’s no color change in 36 months.
Pneumatic actuators adopt double piston structure, with high precision and effective, and stable output torque.
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 uses 1.1 times pressure than standard pressure.
Special Test: According to customer’s requirement, we can do any test you need.
