World-Valve’s WVFL-70-2 series concentric double flanged butterfly valves have been updated.
The valves have a fully vulkanized liner for on and off and control services for liquids and gasses in general services, as well as the marine, power, chemical, petro, and on and offshore applications.
Benefits of the improved double flange valve include low-operating torques, sealing properties, reliable bond linings and easy installation.
