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.

Manufacture and supply:	Acc. to TU 3700-001-55604618-2013

Nominal diameter:	DN 50 – DN 2400 mm
Nominal pressure:	- PN 6, 10, 16, 25 kgf/cm2
Temperature of working medium:	Up to +200 °С depending on the seat material
Operation:	– gearbox DN 100-2400 mm – electric or pneumatic actuator DN 100-2400 mm
Leakage class:	«А» acc. to GOST 9544-2015
Main working mediums:	Water, oil, oil products, water-gas-oil mixtures, drainage and sewage, sea water
Connection type:	- flanged Connecting flanges according to GOST 33259-2015
Installation position:	Any, except the position "electric actuator down" for valves with electric actuator
Flow direction of the working mediums:	Unidirectional, along the arrow on the valve body, bidirectional upon request
Flow rate of the working medium:	Not more than 1,0-5,0 m/s (for liquids)
Climatic version:	У, УХЛ, Т, ТМ, ТВ acc. to GOST 15150-69

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.
