- FAF3800 Double Eccentric Flanged Butterfly Valve; operating through the disc rotating with a quarter turn (90 degrees), ensures 100% sealing with the sealing “T” section ring fixed to the outer diameter of the disc fully facing the seat surface inside the body pe-rimeter made of stainless steel welding. The WRAS approved epoxy coating is suitable for potable water systems.

*** Double Eccentric structure ensures low operating torques with zero leakage performance
*** Inner and outer surfaces of the valve are coated with average 250 microns thickness of fusion bonded epoxy. (FBE) min 300micron available upon request
*** Higher thicknesses are available upon request.
*** Low moments are obtained by decreasing the friction through self-lubricating bushings
*** Can bear high stretching stresses on the pipeline through the duc-tile iron body and disc
*** High impact resistance
*** Reduces the pressure loss through the disc designed in accordance with the direction of flow
*** Pressure loss is at minimum level by double shaft design
*** Sealing gaskets made of EPDM (default), NBR or VITON supplied according to operating conditions and demand can be disassem-bled and replaced easily in field conditions
*** With the o-rings on the bearing bushings, disc pin holes are protect-ed against corrosion (Dry shaft)
*** Retaining ring is assembled to the disc with imbues bolts, the disc is protected against corrosion by placing o-rings under the bolts
Through the gearbox assembled on top flange, it maintains open-ning/closing the valve with very low torques
*** Lifting lugs and feet ease the weight balance during transport and installation
*** With the stainless steel welding, in the valve will have higher sealing resistance.
