AsalAra Triple Offset Butterfly Valve
- Triple Offset Butterfly Valve
The AsalAra Triple Offset Butterfly Valve incorporates a sophisticated design with three distinct offsets: the shaft is positioned outside the centerline of the sealing surface and the sealing surfaces are designed as conical profiles. This eliminates friction between the disc and seat during operation, resulting in zero leakage capability and an extended service life.
This valve is engineered for critical applications requiring bubble-tight shutoff, such as in oil and gas, petrochemical, power generation, and other severe service industries. Its metal-to-metal sealing mechanism enables reliable performance at high pressures and temperatures, including cryogenic and high-temperature steam applications.
Manufactured using premium materials and precision engineering, the triple offset butterfly valve ensures minimal torque for operation, excellent flow control, and long-lasting durability with minimal maintenance.
