5.3.1.6 Function
BOA-Control IMS
BOA-Control IMS balancing valves are equipped with a set of sensors for measuring
flow rate and temperature. The permanently attached set of sensors can be
connected to a measuring computer (BOATRONIC MS or BOATRONIC MS-420) which
processes the measured values and displays the specific system flow rates; the
required operating data are set by appropriate adjustment of the valve plug position
via the handwheel. The balancing valve setting can be secured by the locking device
mounted to the body. Prior to the first measurement, the data of the fluid handled
must be entered in the measuring computer.
BOA-Control IMS DN 15 to 200 valves have single-piece bodies (100) with flanged
ends without separate bonnets. The globe valves are provided with an elastomer
stem seal. The functional unit consists of the valve disc (350), the stem (200) and the
handwheel (961). The stem (200) passage is sealed by a profile ring (412). The stem
seal is maintenance-free and does not require re-tightening. The set of sensors is
permanently glued to the measurement bosses on the valve body.
BOA-Control IMS DN 250 to 350 valves consist of the pressure-retaining parts, i.e.
body (100) and body bonnet (161), and the functional unit. The functional unit
consists of the stem (200), the throttling plug (350), the bellows (442), and the
handwheel (961). Body (100) and body bonnet (161) are joined by means of hexagon
head bolts (901) and hexagon nuts (920) (for EN-GJL-250) or by means of studs (902)
(for DN 350 EN-GJS-400-18-LT) and sealed to atmosphere by the joint ring (411). The
stem (200) passage is sealed by means of the bellows (442) in accordance with TA-
Luft [German Technical Guidelines on Air Quality Control]. The back-up gland
packing (461) is tightened by means of two stuffing box screws (45-6) at the stuffing
box ring (454).
The seating faces of the body (100) and/or the throttling plug (350) are made of rust-
proof materials as standard. The set of sensors is permanently glued to the
measurement bosses on the valve body.
BOA-Control
BOA-Control balancing valves are equipped with two measurement bosses in
preparation for flow rate and temperature measurement. Attaching a set of sensors
and connecting them to the appropriate BOATRONIC MS measuring computer
enables the user to display the specific system flow rates and to set the required
operating data by appropriately adjusting the valve plug position via the handwheel.
The balancing valve setting can be secured by the locking device mounted to the
body. Prior to the first measurement, the data of the fluid handled must be entered
in the measuring computer.
BOA-Control DN 15 to 200 valves have single-piece bodies (100) with flanged ends
without separate bonnets. The globe valves are provided with an elastomer stem
seal. The functional unit consists of the valve disc (350), the stem (200) and the
handwheel (961). The stem (200) passage is sealed by a profile ring (412). The stem
seal is maintenance-free and does not require re-tightening. BOA-Control is
equipped with two sensor bosses on the valve body in preparation for measuring.
