Description

Structurally valves of series PA700 are made with a double offset of the disk - relative to the valve body axis and the pipeline axis. This design reduces wear of the seat parts and reduces the torque required to open and close the valve. A soft seat of EPDM, NBR or Viton is manufactured in the form of a removable O-ring on the disc, which simplifies its quick replacement in case of wear and extends the valve service life.

With opening angles up to 20-70° valves can be used for throttling the flow of working medium Connection type is flanged.

Valves are designed for installation on process pipelines in metallurgical, gas processing, petrochemical, oil refining, chemical industries, fuel and energy complex enterprises, housing and utilities facilities, water supply and sanitation systems.
