Frequently Ask Questions

It is a double-offset butterfly valve fitted with a resilient rubber seat, designed to provide reliable isolation, low operating torque, and bubble-tight shut-off.
A resilient rubber seat provides excellent sealing and bubble-tight shut-off for compatible fluids and operating conditions.
Yes. Nickel-plated ductile iron disc construction is available as an option, according to the product specification.
The double-offset geometry allows the disc to move away from the seat during opening, reducing rubbing, friction, and seat wear.
