+ butterfly VALVE I CATEGORY — concentric rubber lined butterfly valve — high performance double offset butterfly VALVE — awwa c504 rubber seated d.i butterfly valve 
CONCENTRIC RUBBER LINED BUTTERFLY VALVE
⌈DISTINCTIVE FEATURES⌋ □ Concentric Butterfly Valve ■ Rubber or PTFE Lined □ API 609 Butterfly Valve ■ Cast Iron or Ductile Iron □ Wafer, Lug or Flanged ■ Resilient Seat □ Bi-Directional Seal ■ Lockable Lever
– MAIN CHARACTERISTICS – □ Glofa concentric rubber lined butterfly valves are with simple structure and easy to produce, the center of stem, disc and valve body are in same position. The valve are lined by rubber such as Natural Rubber, or NBR, EPDM, which have been widely used in services containing corrosion medium like strong Acid or Alkali. The center lined butterfly valve are with high precise connection with excellent strength, suitable to operate by lever, gear, electric or pneumatic.
– DESIGN ADVANTAGES – ■ The butterly valve is of compact structure and with superior sealing, and there is no leakage from the stem. Glofa rubber lined butterfly valve are with perfect sealing capability, less torque, easy to maintenace, besides, the seat and packing could be replaced. They are bi-directional seal and could be achieved zero-leakage for both. By the way, the sealing materials are with high capability of aging resistance and corrosion resistance, the service life are long. Glofa also supply pinless butterfly valve design which may eliminate potential leakage point at the disc and shaft joints, and perform better in high corrosive medium.
