Butterfly Valve Double Eccentric Flanged FAF3800

PROPERTİES

• 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 ductile 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 disassembled and replaced easily in field conditions.
• With the o-rings on the bearing bushings, disc pin holes are protected against corrosion (Dry shaft)
• Retaining ring is assembled to the disc with imbus bolts, the disc is protected against corrosion by placing o-rings under the bolts.
• Through the gearbox assembled on top flange, it maintains openning/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.
