Wafer Type Butterfly Valves
Nickel-Disc Wafer Butterfly Valve
Nickel-disc wafer butterfly valve; GG-25 cast iron body with nickel-plated GGG40 ductile iron disc and wafer type butterfly valve clamped between two pipe flanges with bolts. Nickel coating protects the cast disc against corrosion while offering a more economical solution than stainless steel disc models.
Operates to +130 °C with EPDM seal. Operating pressure is PN16 for DN25–DN300 range and PN10 for DN350–DN600 range; flange connection is PN16. It is the most commonly used butterfly valve type in heating, cooling, air conditioning and general water lines. Manufactured to TS EN 593 standard; more economical PN10 series also available.
