The high-quality wafer butterfly valves provided by Qigao Valves completely exceed the specifications of hygiene standards, while also featuring unique flow characteristics and capabilities; high-performance wafer butterfly valves meet the requirements of various working conditions.

Features:

• Minimum coating thickness 250 μm.

• No pores (3000V spark test).

• High adhesion to metal (minimum 12 N/mm2). All diameter butterfly valves can withstand a shell pressure test of 6.4 MPa.

• Special valve seat seal design, with a tongue-and-groove seal combined with the valve body, offering superior performance compared to traditional seals.

• Pinless disc design, eliminating leakage from the pin shaft, resulting in lower head loss and easier installation and removal.

• The valve body is made of high-strength ductile iron material, with the metal surface electrostatically coated with epoxy resin, with a minimum average thickness of 250 μm.
