Triple Offset Butterfly Valves, Lined Butterfly Valves Manufacturer In India

Triple eccentric pneumatic butterfly valves are suitable for both throtting and positive isolation applications. These valves are capable of bi-directional flow control, zero leakage, low fugitive emissions and stream-based applications (up to 550.c)

When the disc is closed, the seal ring (on the disc) energises the seat (on the body) there by proving a snug – tight high – performance fit.

Due to the triple offset sealing system, the disc moves smoothly and free of friction at all points along the specially designed body seat & disc seal.

The laminar seal is constructed with grafoil layers sandwiched between metal laminations. This resiliency of the seal flexes and energizes according to the compressive forces generated and allows for minor body deformations due to temprature fluctuations without the risk of jamming. This provides a uniform wedding effect and ensures bubble tight shut-off.
