Butterfly Valves: A Closer Look
Butterfly valves offer true isolation and control capabilities in a single product. Designed for accurate flow and pressure control, they are ideal in applications where positive isolation is required. Butterfly valves offer reliable high-cycle service for applications in the Oil & Gas (upstream and downstream), Energy (power and steam distribution), Chemical, Petrochemical, Pulp & Paper, HVAC (Institutional), Water and Waste Water Treatment, Life Science and Food & Beverage industries. Butterfly valves can replace gate, ball and globe valves very cost-effectively.
