Butterfly Valve

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 minimized 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 insitu moulded seat does not deform with age, and hence the operating torque stays low and consistent during the entire life cycle of the valve. High reliability and consistent torque make Aquaseal the ideal valve for actuated systems.

Assured Shaft Sealing
The flat profiles on the top and bottom of Aquaseal Plus disc engage with matching profiles on the body liner, and the large area of contact prevents leakage to atmosphere. Integrally molded O-Ring that compresses around the blowout-proof shaft provide a secondary seal.

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

Enhanced Reliability
The rugged body is designed to withstand pipeline stresses and vibrations. Further, enhanced liner thickness assures reliable performance over an extended service. Reinforcements are provided on Aquaseal disc also.

Lower Torque, Longer Life
The Aquaseal disc is profiled for smoother flow. Further the coating/ encapsulation of Nylon and EPDM on the disc helps to reduce torque and prevent disc damage.

Reliable Drive
In Aquaseal a two-piece shaft is employed for closer control and smooth operation. The shaft is Xylan-coated to reduce friction and improve wear resistance. While the square shaft provides positive drive, the bottom shaft acts as a pivot for operational ease.
