Product views and applications
Volume flow controller ...Reg-V...-CT
Description
The ExReg-V... flow controller is an indispensable integrant in Building
Management Control Equipment for Chemical, Pharmaceutical, Industrial
and Offshore plants for use in hazardous areas of zones 1, 2 (gas) and
21, 22 (dust).
Highest protection class (ATEX) and IP66 protection, small dimensions,
universal functions and technical data as well as an optional stainless
steel housing guarantee safe operation even in harsh environments.
ExReg-V... is used directly in hazardous areas for control of air flows in
ventilation systems. To complete the technical solution an additional
damper actuator type ExMax-...-CY or ExMax-...-CYF (with Fail Safe
spring return) is required and also a ventilation damper with orifice plate
and a known shield factor (called k-factor).
All controllers are programmable on site with menu guide. The internal
PID control structure is simple to use and automatically configured for
standard applications. The display shows the current status during
operation for the actual value, setpoint and actuator position (can be
disabled if required).
...Reg-V...-OCT and ...-OVA offshore versions are equipped with stain-
less steel tubing Ø 6 mm.
