Smart Shield’s Flexible expanded pure graphite pressure sealing / self sealing/ Bonnet Sealing rings  represent a major enhancement of the operational capabilities of graphite sealing rings used on valve stems . They are manufactured either plain or special SS wire mesh / foil along the cross section. They are available in square – rectangular – angular or any other cross sectional profile. The strong and dimensionally stable profile makes them suitable on gate, Globe and other types of valves. Excellent conformity to body /bonnet and requisite compressibility of Smart Shield SSR enables unmatched sealing; out classing asbestos or soft iron gaskets. Wide applicability in various media, temperature and pressure further add to the versatility of Smart Shield SSR; backed by sound technical know how, making it a popular choice over the competition

Advantages

• Greatly reduce the torque needed for efficient valve action
• Save on power consumption and enable smaller actuators to be used
• Lowers the break-out friction for smoother valve operation
• Retain exceptionally low friction characteristics for up to 20,000 valve cycles
• Subsequent manual adjustment extends performance to 60,000 cycles
• Fire-safe capability enables rings to be used in plant subjected to fire rating tests

• Sizes: As per Drawings,Dimensions and types of valves (OD Upto 800 mm)
• Density:1.8 gm/cc or more depending upon reinforcements
• Thickness: upto 100 mm
