Resilient Seated Gate Valve (Sfrero F5) FAF 6200

PROPERTİES 

• 100% tight sealing is achieved through EPDM covered wedge fully contacting the fusion bonded epoxy coated flow surface.
• The body and bonnet are manufactured from ductile iron castings. It is resistant to high tensile stress occurring in pipelines.
• Low operating torque due to plastic sliding guides on the wedge
• Maintenance-free and corrosion-resistant stem sealing.
• With O-ring sealing.
• Up to DN 300 (inclusive) sizes are supplied with hand wheel as default DN 350 (inclusive) and above can be supplied with gear box as optional.
• Large conical stem hole in the wedge prevents stagnant water.
• Wedge and body guide rails ensure stable operation.
• Stainless steel stem with rolled threads for high strength & low operation torque.
• Inner and outer surfaces are coated with minimum 250 microns fusion bonded epoxy. 300 microns is available.
• Suitable to use with aboveground and underground applications. Can be operated with actuator, gearbox, handwheel and extension spindle.
• The top of the shaft bearing and shaft nuts are made of MS58 brass. High precision machining enables low operation torques.
• Full bore characteristics without distruption of flow results in low pressure drops across the valve.
