Steam Trap MK 35/31

Thermostatic steam trap MK 35/31 with membrane regulator. Corrosion-resistant thermostatic capsule unaffected by waterhammer. Integral strainer. Asbestos-free cover gasket (graphite/CrNi). Installation in any position. The traps with standard capsule “N” discharge the condensate with virtually no banking-up, The traps with special capsule “U” with an undercooling of approx. 30 K (degC). 

MK 35/31 with tandem seat

In particular for low condensate flowrates. Optionally either with standard capsule “5 N 1” or undercooling capsule “5 U 1”. 

Mechanical: 

PN25

Max Temperature: 400°C

DN 10-15

End Connections:

+ Screwed sockets

+ Socket Weld

Features of the MK series

+ Very sensitive response characteristic

+ Function is not impaired by high back pressure
+ Automatic air-venting (trap can be used for thermal air-venting in steam systems)
+ Installation in any position (horizontal and vertical lines)
+ High hot-water capacities even with low differential pressures

+ With tandem seat (double sealing) for low condensate flowrates
+ Stainless steel internals (corrugated membrane of Hastelloy)
+ Design “U” with undercooling capsule: utilization of a certain amount of sensible heat by banking-up of condensate, decreasing the amount of flash steam
 

Application

MK 35/31: For low condensate flowrates, steam-tracing, steam-line drainage, air-venting 

MK 35/32: For medium condensate flowrates, steam tracing, drainage of heat exchangers, air venting
