Valves

BOMAFA develops and manufactures the right products for your plant, whether as individual valves or complete HP-IP-LP turbine control systems. Precise, holistic coordination of the valves - from the high-pressure diverter station to the vapor-extraction basket in the condenser - efficiently minimizes piping system costs. Always in compliance with strict standards for sound emissions and operational safety.

Turbinen Bypass Station

Turbine control systems

Whether as individual fittings or complete HP-IP-LP turbine control systems, we offer the highest quality through precise tuning. Our turbine control stations are:

  • Designed for high-frequency, flexible power plant operation via KS-InductiveCoat
  • Customised with process-specific / equal-percentage / linear control characteristics
  • Superheated steam cooling possible to 5 ° C above saturated steam
  • Use of modern pneumatic or hydraulic drive systems for fast vapor transfer (open / close) <1 sec

Control valves

steam control valves

Steam control valves are used in power plants, chemical plants and in the processing industry to safely and accurately control steam pressures and temperatures. BOMAFA performs the pressure reduction through spindle-hole bushing systems step-by-step undercritical and particularly low-noise. Hot steam cooling is tailored to the process of pressure reduction, creating a solid system within a valve. Our control valves are:

  • Designed for maximum availability in continuous operation with short revision times
  • Customised with process-specific / equal-percentage / linear control characteristics
  • Superheated steam cooling possible to 5 ° C above saturated steam
  • Use of modern pneumatic or hydraulic drive systems for exact steam control

Dump Tubes

Dump Tubes are used where gaseous or vaporous media are released. Mostly they are used after LP steam control valves in the transition to capacitors. Our Dump Tubes offer:

  • Single or multi-stage constructions
  • Complete housing or dished bottom as connection to the condenser
  • noise reduction

HP-Gate Valves

BOMAFA high-pressure gate valves are designed for optimum shut-off of pipes at high pressures and temperatures. Due to the cylindrical passage in the valve body, the velocity of the flowing medium is not significantly changed, so that the pressure loss is hardly greater than in the connected pipeline with the same dimensions. Our gate valves offer:

  • Self-sealing lid closure
  • Flexible double wedge plates, fully guided with seated seats
  • Bypass to reduce the required opening force
  • Overpressure protection by relief bore or by pressure relief valve with rupture disc

Desuperheaters

Superheated steam coolers are used to cool superheated steam in pipelines and to produce process steam at given temperatures. In the case of BOMAFA superheated steam coolers, the cooling water is preferably injected in the area of the smallest flow cross-section, with correspondingly highest vapor velocities. Due to the streamlined design, impermissible pressure losses are effectively prevented. Our steam boilers offer:

  • Ring cooler with spring-loaded nozzles
  • Venturi cooler with annular gap or nozzles (swirl atomization)
  • motion steam-assisted superheated steam coolers
  • Multi-stage, regulated nozzle injection coolers
