AXISYMMETRIC BACK VALVE

 

NOMINAL BORE DIAMETER: from 50 to 400 mm.

NOMINAL PRESSURE: from 1,6 to 16,0 MPa.

TECHNICAL REQUIREMENTS AND STANDARDS: TU3742-003-37961533-2015

TEMPERATURE OF WORKING MEDIUM: up to +360°С.

 

APPLICATION:

The item is installed on the pipeline as a locking device to prevent backflow of the conducted (pumped) medium in the pipelines in case of shutdown of the pump or emergency.

DESIGN FEATURES:

Axial check valve – smoothly and quickly responds to pressure changes.

The auxiliary spring ensures that the valve closes quickly and without any shock (and thus in a spark-safe way) without any possible backflows or pressure pulsations.

The design of the valve is so that the flow parameters after it are restored immediately at the outlet section.

Valves have low resistance coefficient.

CLIMATIC MODIFICATION ACCORDING TO GOST 15150:

  • «ХЛ» (areas with a cold climate and ambient temperature ranging from -60°C to +40°C);
  • «УХЛ» (areas with moderate to cold climate and ambient air temperature ranging from -60°C + 40°C).
