Pressure reducing valves
ARI steam pressure reducer/pressure reducer type PREDU for reducing saturated steam pressures, available in EN JL 1040 (formerly GG 25) and EN JS 1049 (formerly GGG 40.3) materials as a mechanically operating pressure regulating fitting incl. feed vessel for protecting the regulating diaphragm. Nominal sizes from DN 15 to DN80 available from stock. Precise and constant regulation of the output pressure is optimally possible by selecting the right drive. Of course, all appropriate fittings such as isolation valves, strainers and pressure gauges, etc. are also available in our shop. We will also be delighted to supply you with entire pressure reduction sections/pressure reduction stations with upstream and downstream fittings, safety valve or bypass capacity, if required, as well as pressure gauge combinations that are ready to install. Are you looking for fittings that you can’t find in our web shop? -> Contact us by e-mail or telephone!
