Float steam traps ASTA PM521 and PM523 DN15–25 with steam lock protection valve

DN: 15-25
PN: 25 bar
t max°: 250 °С
Body material: ductile iron
Connection: threaded, flanged

Overview

ASTA PM THERMOKON is a mechanical float steam trap with a built-in bypass needle valve designed for efficient condensate drainage from steam lines. It is used in systems with siphon condensate drainage. The rise of condensate relative to the drainage point, load spread, and the specifics of equipment operation can cause the formation of steam locks in front of the steam trap, which complicates the drainage of condensate as it forms and can disrupt the operation of the equipment. The built-in steam release valve allows for a small adjustable steam flow into the bypass of the main valve, eliminating steam locks. They are mainly used in the piping of rotating drying cylinders, cooking boilers, consumers with a rising condensate line, etc.

Advantages

  • High flow capacity
  • Built-in thermostatic air vent
  • Wide range of operating pressures and temperatures
  • Anti-corrosion treatment of the inner surface of the housing
  • Continuous condensate drainage
  • Possibility of changing the flow orientation (for DN15-20)
  • Erosion deflector
  • Possibility of repairing the condensate drain without dismantling it from the pipeline

Options on request

  • ASTA KDA — valve for automatic removal of condensate from the float chamber
  • ASTA PV — valve to prevent the formation of a vacuum
  • Various materials for the housing (carbon / stainless steel)
