The Self-Sealing Ring we provide are manufactured using special wire mesh or foil along the cross section. It is a flexible pure and expanded graphite pressure sealings. These are available in rectangular, square, angular or other cross-sectional profiles. The strong and dimensionally stable profile that is has makes it suitable for gate valves, globe valves and other types of valves. Its robust conformity to body /bonnet and compressibility helps in having unmatched sealing with class asbestos or soft iron gaskets.
Its Wide applicability in different media, pressure and temperature further adds to the versatility of Win Graph SSR. Besides, being backed by sound technical know-how, makes it the right choice over the completion.
