Industrial butterfly valves provide reliable flow control and isolation across a wide range of pipe sizes and applications. Like a ball valve, operation requires just one quarter-turn to move from fully open to fully closed. A plate or disc is in the center of the pipe and has a shaft passing through it that is connected to a ten-position lever handle, gear-operated handwheel, or pneumatic or electricactuator on the outside of the valve. Rotating the handle turns the disc either parallel or perpendicular to the flow. U.S. Valve's resilient seated butterfly valves are available in lug body, wafer body, and ASME BPE Tri-Clamp/Sanitary styles, from 2" through 24", with Buna-N, EPDM, and Viton® seat options to suit a wide range of process media.Butterfly valves use a rotating disc to regulate or shut off flow, offering a compact, lightweight alternative to gate or ball valves. The disc remains in the flow path at all positions, making butterfly valves well-suited for applications where space, weight, and cost are priorities. All U.S. Valve butterfly valves are designed in accordance with API 609 and tested to API 598, with bodies available in ductile iron, 304 Stainless Steel, and 316 Stainless Steel and disc materials in 304 stainless steel, 316 Stainless Steel, or nickel-plated ductile iron. Seat options include Buna-N, EPDM, and Viton® to accommodate a wide range of process media.

Frequently Asked Questions About Butterfly Valves
What is a butterfly valve?
A butterfly valve is a quarter-turn rotary valve that uses a disc mounted on a rotating shaft to control or stop fluid flow. Butterfly valves are lightweight, compact, and economical compared to ball or gate valves, making them a popular choice for water, HVAC, and industrial applications.
What is the difference between a wafer and lug butterfly valve?
A wafer style butterfly valve is sandwiched between two pipe flanges and held in place by bolts running through both flanges. A lug type butterfly valve has threaded inserts (lugs) that allow it to be bolted to flanges from each side independently, making it suitable for dead-end service where one side of the pipeline may be disconnected.
What sizes are available?
U.S. Valve butterfly valves are available from 2" through 24" in ASME Class 150 pressure ratings.
What seat materials are available?
We offer Buna-N (NBR), EPDM, and Viton® seat materials to suit a variety of process fluids and temperature ranges.
