SIERRA model 7200 is concentric rubber lined valve, double flanged or wafer type that shall be suitable for installation between flanges. Face to face according to EN 558 table 5 basic series 20 valves are drilled in accordance with EN 1092-2. The disc has a profiled sealing edge which requires minimal deformation of the liner to achieve a tight sealing. This gives less wear of the liner and low operating torques.  The 7200-butterfly valve is an excellent valve for isolation purposes and it might also be used for throttling purposes under certain conditions.

Main Product Features

• Symmetric and slim design of disc ensures favorable flow, low pressure loss and energy cost saving
• Smooth machining of disc edge also provides less deformation on the rubber sealing thus longer life of the valve
• Absolutely tight sealing with flow in either direction
• The valve body and disc are accurately machined which results in low operating torque and long service life and reliability
• Shaft bearings design prevents shaft deflection and guarantee optimum guidance even after many years of operating service
• Can be supplied in flanged or wafer design
• The valve can be installed in any desired position
• Disc shall be made of ductile cast iron, stainless steel, Duplex, Aluminum bronze
