Steam Traps MK 35/2S

Data sheet 810739-02 Issue: 03-2024
Thermostatic Steam Trap
MK 35/2S, MK 35/2S3 PN40/CL300
DN 25, NPS 1" Description Thermostatic steam traps with corrosion resistant 5H2 membrane regulator capsule, unaffected by water hammer and with
flat seal. With integral strainer. Installation in any position.
The “H” version discharges the condensate supercooled to approx. 5 K. The superheating of the steam at the membrane
regulator capsule must not exceed 5 °C.
Design
MK 35/2S With two 5H2 membrane regulator capsules. For condensate flowrates up to e.g. 1100 kg/h at Δp 5 bar.
MK 35-2S, MK 35-2S3
MK 35/2S3 With three 5H2 membrane regulator capsules. For condensate flowrates up to e.g. 1700 kg/h at Δp 5 bar
Fluids The equipment is designed for the following fluids (in accordance with the EU Pressure Equipment Directive or Pressure
Equipment (Safety) Regulations in the UK):
MK 35/2S, MK 35/2S3 ■
Group 2 fluids
Chemical and corrosive influences must be taken into consideration.
Use in potentially explosive atmospheres The equipment does not have its own potential source of ignition (as per ATEX Directive). Please note the following:
Once installed, static electricity may arise between the equipment and the connected system. If the equipment is used in
potentially explosive atmospheres, the plant manufacturer or owner is responsible for discharging or preventing possible
static charge.
If it is possible for fluid to escape, e.g. through actuating mechanisms or leaks in threaded joints, the plant manufacturer or
owner must take this into consideration when dividing the area into zones.
Function
MK 35-2S
The equipment is used for discharging condensate from steam or for venting steam lines.
The condensate is discharged by two or three membrane regulator capsules and associated nozzle holder insert.
