- Double Offset Butterfly Valve
Falcon Flow Control Double Offset Butterfly Valve
A double offset butterfly valve engineered for superior sealing performance and reduced seat wear in demanding industrial applications.
Full Description
The Falcon Flow Control Double Offset Butterfly Valve features a design where the valve disc is offset from the centerline of the valve body and stem in two ways—axially and radially. This double offset eliminates the rubbing action between the disc and the seat during operation, significantly reducing wear and extending valve life.
This valve is ideal for applications requiring tight shut-off and high cycle performance under medium to high pressure and temperature conditions. The metal seat construction allows use in harsher environments, including steam, gas, and high-temperature fluids, where resilient seats would fail.
Manufactured with precision-engineered components and high-quality materials, the double offset butterfly valve combines durability with ease of operation, featuring a quarter-turn mechanism for fast opening and closing.
