, must
be connected to the drain since there is no pressure upstream of the steam control valve to push the
condensate back to the boiler. Therefore, normal draining design applies on the condensate side of the
header steam trap slope to evacuate the condensate, and a P-trap (6” or 152 mm) to avoid the steam
vapor coming from the drain. All other steam traps can be connected to the condensate return line.
Stage 7 – Isolating Valve Installation
Any installation work must be carried out by suitably qualified personnel.
Isolating Valve Positioning
The valve body must be positioned properly to have the steam supply going into the A port and exiting
from the AB port. Do not refer to the orientation of the actuator head for positioning, since the head can
be reversed. Install the actuated valve between 20 to 30 degrees from the vertical line to reduce the heat
transfer to the actuator head.
