Frequently Ask Questions

It is a wafer-style butterfly valve with a double-offset disc and shaft arrangement, designed to reduce seat contact during operation and provide reliable isolation with lower operating torque.
The valve has a compact body installed between compatible pipeline flanges, rather than having integral flanges on the valve body.
Alis Valves manufactures and supplies Wafer Type Double Offset Butterfly Valves for oil & gas, petrochemical, power generation, water treatment, chemical processing, HVAC, and other industrial applications.
The double-offset design causes the disc to move away from the seat early during opening, reducing rubbing, friction, and seat wear.
Yes. The standard listed temperature range is -20°C to +250°C, while the metal-seat configuration can be used up to approximately +550°C, subject to the complete valve design and application conditions.
