3 Operation

Proceed as follows:

− Unscrew the ller plug on the chamber

and undo the vent screw on the dia­phragm actuator.

− For applications with steam: use the sup-
plied plastic funnel or a watering can to
ll the chamber with water until it over­ows at the vent hole on the actuator.

For applications with other liquids, ll the
compensation chamber with the process me­dium.

− Screw the ller plug back on the cham-
ber and tighten.

1 Application

A compensation chamber is installed in the
control line together with the listed regulators
and actuators. The liquid lled in the cham­ber (water for steam control) acts as a buffer
for process medium temperatures above
150°C and for steam. It prevents any hot
process medium coming into direct contact
with the actuator diaphragm and damaging
it.

2 Installation

Install the compensation chamber at the
highest point of the control line. Make sure
that the control line between the diaphragm
chamber and compensation chamber as well
as between the pipeline and the compensa­tion chamber inclines downwards at a ratio
of at least 1:10.

Connect the control line at the side of the
pipeline transporting the process medium or
the manifold.

The mounting position of the chamber is in­dicated on the chamber by an adhesive la­bel with an arrow as well as by the word
oben (top) impressed on the chamber. It is
imperative that the mounting position of the
chamber is observed to guarantee the safe
functioning of the regulator.

Weld the control line coming from the pres­sure tapping point to the R
