    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.

    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.

    The valve seat is wide edge seat, sealing gap is wider than regular type, makes the sealing for connection easier. Wider seat also easy to install than narrow seat. The stem direction of the seat has lug boss, with O ring on it, archive the second sealing of the valve.

    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.

    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.

    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.

    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.

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

    Pneumatic actuator adopt double piston structure, with high precision and effective, and stable output torque.
