150LB 5 inches Butterfly valve, cast iron body and disc, Seat NBR

Butterfly valves are used in industry and manufacturing. The devices are used on pipelines with a large pipe diameter that transport the medium under low pressure and low flow. Depending on the model, the shut-off valve discs can be made of cast iron, stainless steel or alloy steel. Butterfly valves are universal for their intended purpose. Advantages of butterfly valves: - compact size; - light weight; - Class A tightness;  - minimal hydraulic losses ; - easy installation, maintenance, operation ; - wear-resistant anti-corrosion materials. The use of butterfly valves reduces installation costs, minimizes hydraulic resistance, and allows you to effectively regulate flows in main systems.
