    Product Advantage

    Our valve has standard thickness according to GB26640, makes it capable of holding high pressure when needed.

    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.

    The valve seat with 3 bushing and 3 O ring, helps supporting the stem and guarantee the sealing.

    The valve body use high adhesive force epoxy resin powder, helps it adhere to the body after melting.

    Bolts and nuts use ss304 material, with higher rust protection capability.

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

    Each product of ZFA has material report for the main parts of the valve.

    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℃.

    Pneumatic actuator adopt double piston structure, with high precision and effective, and stable output torque.
    Special Test: According to customer’s requirement, we can do any test you need.

    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.

    All valve body casted by precise casting body, DI, WCB, Stainless Steel and many other materials, with perfect appearance, each batch has its casting stove number, easy to trace for material protection.

    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.
