Butterfly valves

GF Piping Systems has introduced its new series of butterfly valves type-578 in the dimensions DN50 to DN300, which are specially suited for chemical and water treatment applications. The newly developed glass-fiber-reinforced-plastic lug housing features high stability, low weight and good corrosion and UV resistance. Compared to metal valves of the same dimension, the type-578 valves save up to 50-percent weight due to its housing. Likewise, stainless-steel-threaded lug inserts ensure that the valve can be centered perfectly between the flanges.
