RTK MV 5291 V-D / PV 6291 V-D

Electric or pneumatic actuated continuous blowdown control valve for steam boilers

Continual evaporation during steam generation increases the dissolved solids content in the boiler water. To keep this content within the limits and in accordance with regulations is important to blow out the boiler water continuosly or with intervals.

RTK MV (electric) 5291 V-D, PV (pneumatic) 6291 V-D are actuated control valves created for steam boiler continuous blow down for excact dosing of blow down flow rate. The dimension of the continious blow down valve is on normal operation 5% of the boiler steam rating. The maximum blow rate (full valve opening) is sized for 10% steam flow.

Meanings V or D are accordingly with or without sampling valve.
