    Product DetailProduct Advantage

    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.

    Suitable Media: Wafer and other neutral medium, working temperature from -20 to 120℃, the application of the valve can be municipal construction, wafer conservancy project, water treatment etc.

    ZFA Valve strictly execute API598 standard, we do both side pressure testing for all the valve 100%, guarantee deliver 100% quality valves to our customers.

    The valve body adopt GB standard material, there’re total 15 processes from iron to valve body.

    We use CNC machining to process the valve disc, control the precision of the valve by ourselves, guarantee good sealing property from low to high temperature.

    The electric actuator is a mini design type with compact structure inside, it’ll save your space more than 1/2 so suitable for a more compact space.

    The valve body made of ductile iron, ss304, WCB, SS316(L) etc., it has great mechanical performance when used in high pressure condition.

    The flange type butterfly valve is made by ductile iron, it has a great feature that short face to face dimension and easy to install. The valve torque is small and the sealing surface between the seat and disc is small.

    Our valve can be produced by different kinds of materials, it’s produced by international standard and national standard according to your requirement.
