Product Advantage
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 and disc use stainless steel CF8M material, which is good for rust and wear resistance, heat and cold resistance.
The PTFE Seat: PTFE ultra-fine sub-nanometer powder has ultra-low particle size, chemical stability and corrosion resistance.
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.
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.
