Description

Valves of this series are designed for operation in harsher conditions than valves with a symmetrical disk (high temperatures, more cycles of actuation).

The disk is installed in the body with an offset relative to the axis of symmetry of the valve body and the pipeline axis.

The seat and the disc have a conical profile, which together with a double offset allows the disk to come out of contact with the seat at minimum opening angles.

Connection type is wafer.

Valves of series PA400 are produced with sealing of 3 designs: with soft PTFE seat, in fire-safe design and with "metal-on-metal" seat.

Butterfly valves series PA400 are used in oil refining, chemical industry, metallurgy, technological pipelines of industrial enterprises, in energy industry, shipbuilding.

When operating valves for working mediums other than water, the reliability parameters are determined by the specific mediums, depending on its parameters.

Warranty

The warranty period is 18 months from the date of putting into operation, but not more than 24 months from the date of sale under condition of observance by the consumer of rules of transportation, installation and operation.

Conservation period - 3 years.

Average service life of body parts is not less than 30 years.

Average life removable parts and components – at least 5 years.
