DN150 Wafer Type Butterfly Valve
Our DN150 wafer butterfly valve is constructed from premium GGG50 ductile iron, featuring a compact wafer design, rubber sealing, and lever operation. It provides efficient flow control with low torque, widely used in water treatment, HVAC, and general industrial applications.
Product Description
Our DN150 (6 inch) wafer type butterfly valve is engineered for efficient on/off flow control in general industrial, water treatment, and HVAC systems. As a professional valve manufacturer, we produce this GGG50 ductile iron butterfly valve with a focus on durability, cost-effectiveness, and high performance.
This 6" wafer butterfly valve features a GGGG50 ductile iron body and a stainless steel disc, ensuring exceptional strength and corrosion resistance in water, sewage, and non-corrosive gas applications. The EPDM/NBR rubber lining provides a tight seal, minimizing leakage and reducing operating torque for smooth, effortless handling. Equipped with a lever handle operator, this valve allows for quick, manual operation, making it ideal for applications where frequent adjustments or immediate shutoff are required.
Designed to the DIN 3202 F4 / BS 5155 standard, this wafer butterfly valve features a compact wafer design that simplifies installation—simply bolt it between two flanges without the need for additional accessories. It is compatible with both PN16 (1.6MPa) and 150LB (Class 150) pressure ratings, offering versatility for global pipeline systems. Built to meet CE & ISO quality standards, this valve is a reliable, cost-efficient solution for a wide range of fluid control needs.
