The thermostatic steam trap features minimum stagnant area and a corrosion-resistant membrane regulator unaffected by waterhammer.
Used for discharging condensate and air-venting steam in sterile and aseptic applications.

The membrane regulator with rolling ball features a selfcentering valve cone that can move freely, thereby ensuring steam-tight shut-off unaffected by dirt particles.

High response sensitivity thanks to small dimensions of the regulator (evaporation thermostat). Automatic air-venting and discharge of condensate without any banking-up within the whole pressure / temperature range.
The opening temperature is approximately 5 K below the boiling point.

All parts in contact with the fluid are made of stainless steel and the body gasket is of PTFE (FPM) in accordance with the regulations specified by the Food and Drug Administration (FDA).

The surface roughness Ra of the wetted surfaces is ≤ 0.8 μm, optional: ≤ 0.6 μm.
The surface roughness Ra of all other surfaces is ≤ 1.2 μm.

End Connections / Optional Extra:
For the first installation of the SMK 22-81 and SMK 22-82 an accessory kit is available which consists of:
2 FDA-approved gaskets DIN 32676 -D40- PTFE (with FPM core)
2 Clamps
2 End connections for orbital welding for
– pipes to ISO 1127 (DN 8, 10, 15, 20, 25) or
– pipes to ASME BPE (½”, ¾”, 1″)
– pipes to DIN 11850 (DN 15, 20, 25)
Different sizes of end connections for orbital welding available on request.
