Special Features

• Sizing Calculation in accordance with all international standards such as API 520
• Seat Tightness Test as per API 527
• Body Design and Thickness in accordance with ASME B 16.34
• High Lift Full Nozzle design
• Single Blow down bring for easy maintenance and control
• Maximum inter changerablility of parts
• Special Geometry of Disc’s seal lip allows to minimise the thermal stresses avoiding the distortions that causes leakage through the seat. This is transferred from spindle to disc through a ball. This feature together with low positioning of the centre of thrust, helps in the homogenous distribution of the force on the sealing surface and minimise the side shifting of the disc from the nozzle while opening & closing of the valve. These structural features together with a scrupulous lapping of the seat contribute to obtain high seat tightness and set pressure reproducibility.
