Pressure Seal Valves are intended for high pressure and high temperature applications in all types of fluid, except where severe coking may occur. The Pressure Seal Valves use the process pressure to exericise additional force in the body / bonnet sealing ring, ensuring far superior sealing of this area. The Sealing rings are metallic, thus avoiding the possibility of wear or deterioration. The thrust ring above the sealing rings ensures homogeneous distribution of forces in the entire circumference.
