DN125 Hard Back Seat Wafer type Casting Iron Butterfly Valve

The main charactoristics hard seat back wafer casting iron butterfly valve:

• 1. Compared with the soft-backed valve seat, the hard-backed butterfly valve seat has resin ring inside of the seat.
• 2. The sealing performance is reliable and achieves two-way sealing and zero leakage.
• 3. The hard back seat wafer butterfly valve can prevent the valve body from deforming.
• 4. Casting iron butterfly valve, with strong wear and corrosion resistance, has lower cost and higher competitiveness than other materials.
• 5. Cf8m disc has excellent corrosion resistance.
