Purpose:

The IPU is intended to protect the ECCS hydroaccumulator from pressure exceeding preset values by automatically discharging the medium from the hydroaccumulator.

Purpose:

The IPU is intended for automatic discharge of the working medium in the event of emergency pressure increase above the set value in equipment and pipelines of NPP systems.

Purpose:

The IPU is intended to protect equipment and pipelines of the reactor plant primary circuit from pressure exceeding the permissible safe level by reducing the pressure in the primary circuit due to medium discharge from the pressurizer to the bubbler tank.

Purpose:

The valves are intended for installation on pipelines of general industrial process systems in the nuclear, defense, gas, oil, petrochemical, chemical and other industries in order to automatically prevent reverse flow of the working medium.

Purpose:

The valves are intended to maintain pressure at a preset level downstream on process pipelines of NPP Class 4 safety systems.

Purpose:

Special sewage system valves are intended to collect water and solutions entering room floors as a result of unorganized leaks in case of radioactive circuit leakage at NPPs, and to prevent air communication between rooms connected by special sewage pipelines.

Purpose:

Used as an independent remote control line as part of the pressure compensator IPU system.

Purpose:

The impulse line isolation device is intended for automatic shut-off in the event of leakage exceeding the set response flow rate in the pipeline downstream of the device, as well as for limiting the medium flow in the event of leakage and failure of the isolation device in nuclear power plant systems.

Purpose:

The valves are intended for releasing air from the cooling system of critical consumers during system filling with water when the pump starts, and for admitting air into the system when the pump unit stops, when the system pipelines are rapidly drained.
