Thermostatic Steam Traps MK with Membrane Regulator0 pages
Features of the MK series
nn֕ Very sensitive response characteristic Function is not impaired by high back pressureՕ Automatic air-venting (trap can be used for thermal air-venting in steam systems) Installation in any position (horizontal and vertical lines)Օ High hot-water capacities even with low differential pressures
With tandem seat (double sealing) for low condensate flowratesՕ Built-in non-return valve Stainless steel internals (corrugated membrane of Hastelloy)Օ Design UӔ with undercooling capsule: utilization of a certain amount of sensible heat by banking-up of condensate, decreasing the amount of flash steam Optional extra: Integrated condensate monitoring for MK 45 (temperature or steam loss) L

Air Venting
nnSteam Trap for Thermostatic Air-Venting with Membrane Regulator The thermostatic steam traps with membrane regulators of the MK series can also be used for air-venting. Application Thermostatic steam trap for automatic air-venting and discharge of non-condensable gases and steam/air mixtures from steam lines and heat exchangers .A special type of membrane might be required. >
