Design Features

Concentric Butterfly Valves

Our range includes Concentric Butterfly Valves, available in multiple materials, pressure classes and operating configurations to meet diverse process requirements.

Longer Life

The strength of the vulcanised liner as well as its strong bonding with the body ensure that it doesn’t get deformed and torn by the disc during valve operations. Further, friction during operations is minimised owing to the smooth liner surface. The strong seat and reduced friction greatly enhance service life of the valve.

Tight Sealing, and Consistent Low Torque

Bubble-tight sealing is obtained by the tight interference fit between liner and disc. The moulded seat does not deform with age, and hence the operating torque stays low and consistent during the entire life cycle of the valve. AEW is the valve of choice for actuated systems because of high reliability and consistent torque.

Reliable Drive

Positive shaft-disc connection with anti-blow out is a key feature. The shaft is Xylan-coated to reduce friction and improve wear resistance. Further, the self-lubricated bearings reduce the torque and increase valve reliability.

Ease of Installation

The integral liner of the valve acts as a gasket between the valve and companion flange. The liner being bonded to the body doesn’t get stretched or damaged during installation unlike loose liners.

Lower Resistance to Flow

The discs are hydrodynamically designed to provide minimum resistance to flow and improved flow coefficients.

Assured Shaft Sealing

The flat profiles on the top and bottom of Aqua seal disc engage with matching profiles on the body liner, and the large area of contact prevents leakage to atmosphere. Integrally moulded O-Rings that compress around the top shaft provide a secondary seal. Weather seal is provided to prevent the ingress of foreign particles on valves with flow control lever.

Actuator Mounting Platform

The integral ISO 5211 platform facilitates direct mounting of actuators and gear units, thereby improving system reliability and efficiency.
