Red Valve has introduced a valve designed primarily for clean-water applications. The C-504 Butterfly Valve is available with a variety of seat and disc designs and flange options. A resilient elastomer seat is long lasting and easy to replace. The streamlined disk profile provides smooth flow and ensures a low pressure drop across the valve. The C-504 valves are available in sizes to 144 inches and can be supplied with manual, electrical, pneumatic or hydraulic actuators.
