Information / restriction of technical rules need to be observed!
Operating and installation instructions can be downloaded at www.ari-armaturen.com. ARI-Valves of EN-JL1040 are not allowed to be operated in systems acc. to TRD 110.
A production permission acc. to TRB 801 No. 45 is available (acc. to TRB 801 No. 45 EN-JL1040 is not allowed.) The engineer, designing a system or a plant, is responsible for the selection of the correct valve.
Resistance and fitness must be verified (contact manufacturer for information, refer to Product overview and Resistance list).
Application
The pressure regulating valve PRESO is a spring loaded differential pressure-control valve. The main applications are:
– Pump protection: PRESO inserted parallel to the pump, this secures a minimum flow.
– Application in bypass lines from users, e.g. heat exchanger in thermal oil systems to sustain a minimum flow.
– Parallel to piping systems to avoid to higher differential pressures.
– Pressure maintaining valve to avoid the flashing in condensate systems.
