Here we are mainly talking about the butterfly valve disc, which is installed in the diameter direction of the pipeline. Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. In the cylindrical channel of the valve body of the butterfly valve, the disc-shaped butterfly plate rotates around the valve shaft to achieve opening and closing, and the rotation angle is between 0° and 90°. When it is rotated to 90°, the valve is fully open.
Next, we will mainly introduce the aluminum bronze valve plate.

Q1: Why choose an Aluminum Bronze (C954/C958) disc over standard stainless steel?
A: Aluminum bronze offers superior natural resistance to seawater corrosion, pitting, and marine bio-fouling compared to standard stainless steel. Its excellent anti-dezincification and erosion-resistant properties make it the ultimate, long-lasting choice for offshore, marine, and desalination applications.
Q2: What is the primary difference between C95400 and C95800 materials?
A: C95400 is a versatile, high-strength aluminum bronze excellent for general wear and impact resistance. C95800, on the other hand, contains a higher nickel content (4.0-5.0%), which significantly boosts its corrosion resistance and toughness, making it the premium standard for severe saline and continuous seawater exposure.
Q3: Which valve seat materials are compatible with these discs?
A: The precision-machined, highly polished edge of our aluminum bronze disc pairs perfectly with a variety of elastomeric soft seats, including EPDM, NBR (Buna-N), and Viton (FKM). The ideal seat selection will depend on your system's specific media, temperature range, and operating pressure.
