Product Description

This Smith-Cooper International 160 series lug style butterfly valve is made of iron for compressive strength and resistance to wear. It has a lever handle, Buna-N seat, a stainless steel 316 disc, and flanged connections on both ends. This lug-style valve is secured between two pipe flanges by a separate set of threaded bolts for each flange and is suitable for end-of-line service and removal or replacement of downstream piping. The disc is made of stainless steel 316, which has higher strength and greater corrosion resistance than stainless steel 304. Buna-N seats are high tensile strength and resistant to oil, fuel, and other chemicals. The lever handle rotates the disc in the valve seat to fully open, regulate, or stop flow through the valve. This valve has a maximum pressure of 200 pounds per square inch (psi), and an upper temperature range of 150 degrees Fahrenheit. Flanged connections surround the valve body on both sides for bolting to pipes and for easier installation and maintenance than welded connections. Butterfly valves are used to regulate flow between pipes, tubes, and hoses by rotating a lens-shaped disc in the center of the valve and are suited for high-capacity, low-pressure applications. When the valve is fully opened, the disc face is parallel to the inlet and outlet of the valve, and when the valve is closed, the disc face is perpendicular to the opening of the valve. Butterfly valves may have a handle or lever that aligns with the disc position (open or closed) for manual flow control. They are primarily used in applications including agriculture, water treatment, fire protection, compressed air or gas, and vacuum service. Smith-Cooper manufactures a wide variety of pipe fittings and valves. The company is headquartered in Commerce, California, and meets relevant ANSI, ASTM, and International Organization for Standardization (ISO) 9002 standards.
