Thermostatic Steam Traps MK with Membrane Regulator

Product catalog summary
Overview: This document provides specifications and applications for various models of thermostatic steam traps with membrane regulators, designed for different condensate flow rates and applications such as steam-tracing, drainage, and air-venting.
Specifications:
  • MK 45-1 and MK 35/31: Tandem seat for low condensate flow rates, suitable for steam-tracing, steam-line drainage, and air-venting.
  • MK 45-2 and MK 35/32: Single seat for medium condensate flow rates, used in steam-tracing and heat exchanger drainage.
  • MK 25/2 and MK 35/2 S: Single seat for large condensate flow rates, primarily for heat exchanger drainage.
  • MK 36/51 and MK 36/52: Tandem seat with flat gasket for a range of flow rates, suitable for food, biological, and pharmaceutical applications.
  • MK 45 A-1 and MK 45 A-2: For small and large condensate flow rates, used in steam-tracing and air-venting.
Key Features:
  • Very sensitive response characteristic and not impaired by high back pressure.
  • Automatic air-venting capability, suitable for thermal air-venting in steam systems.
  • Installation flexibility in both horizontal and vertical lines.
  • High hot-water capacities even with low differential pressures.
  • Stainless steel internals with a corrugated membrane made of Hastelloy.
  • Optional integrated condensate monitoring for MK 45 models.
Pressure/Temperature Ratings:
  • MK 35/31 and MK 35/32: Max pressure 18.6 bar at 225°C, 14.4 bar at 400°C.
  • MK 45-1 and MK 45-2: Max pressure 28.4 bar at 250°C, 23.1 bar at 400°C.
  • MK 36/51 and MK 36/52: Max pressure 32 bar at 240°C.
  • MK 45 A-1 and MK 45 A-2: Max pressure 29.3 bar at 200°C, 24 bar at 400°C.
Connection Types and Dimensions:
  • Available in flanged, screwed sockets, socket-weld, and butt-weld connections.
  • Overall lengths vary by model and connection type, with specific dimensions provided for each.
Capacity Charts: The document includes charts showing maximum hot condensate capacities for various models, indicating their performance under different conditions.
