FBGD is a double eccentric flange butterfly valve, with soft seal on the body, it has the lowest operational torque, much less wearing, the dovetail seal design has been proven over half century service with reliability.
Features: The butterfly valve is made of DI body and DI disc.. Advanced newly design with dovetail seal design and captured by epoxy on the back, with multiple raised ring to have more contact with disc but less friction during closure. . The double eccentric design provides less contact area of seal with disc, and less stress at the open position of the disc. . The disc design with arch shape and thru disc can provide better flow capacity, stronger and less weight . The shaft and disc connection with tangential pin which can be exchangeable and provide rigid connection. The DN 100-500MM use flat disc, and DN 600-1200MM use arch shape disc. . Epoxy coated interior and exterior. Valve design meets or exceeds EN 593. . Top flange connection meets ISO 5211-1982, and F/F meets EN 558-1 series 13 & 14.
