Butterfly Valves LBF SERIES VALVES TRIPLE STEM SEALING LBF BUTTERFLY VALVES INTRODUCTION Stem Top stem 'O' ring seal Bottom stem 'O' ring seal Flat surface seal • Butterfly Valves are easy to open & close. • They are easy to install due to their compact design & less space requirements at the place of installation. • We provide Tight Sealing due to close interference between disc & liner. We also provide a Triple Stem Seal which prevents any leakage and also any foreign particles from entering the valve. • The flow control lever as well as the gear unit are designed such that very low torque is required for controlling the valve. Also, the hand lever can be held in several positions whereby the disc position in valve is not affected by the flow pressure. • These valves have very low pressure drop. • We provide all our valves with CED coating which gives better corrosion resistance & hence gives long lasting life. Maximum Working Temperature: 110°C (230°F) MAIN FEATURES • We have designed & manufacture the Lubi LBF series type of Butterfly Valves for General Utility Water applications as well as for HVAC applications. • It is a type of quarter turn valve which means that it can be fully opened or closed when the disc is rotated a quarter turn. APPLICATIONS The main applications of this valve is for general utility water applications as well as HVAC applications. The typical applications areas are as follow: On/off isolation Dead-end service/removal of down stream piping Industrial process water piping Municipal raw water intake Municipal chlorinated water systems Full vacuum Aeration and blower applications.
