Attention! The dependence of the flow rate Q on the pressure P is given by the equation: Q = K√10P, where Q is expressed in liters / minute and P in megapascals.

Possibility of implementation

52 valve with slant reduction

Hydrant can be connected to DN52 water supply due to 52 valve with slant reduction

Nozzle crimping

  • nozzle crimping with aluminum sleeve in standard
  • nozzle crimping with brass sleeve

Ball valve 32 – optional

Possible to use 5/4” ball valve (32)
