Discover the high-quality GOETZE pressure reducers in all-metal design, ideal for drinking water installations, fire extinguishing systems, sprinkler systems as well as maritime and high-rise water installations. These pressure reducers are characterised by their robust design and optimised materials, which are suitable for various water qualities and hot water applications. The solid construction guarantees versatility in numerous areas of application.
Our pressure reducers cover an extensive setting range: the standard range is between 1 and 8 bar, supplemented by outlet pressure ranges of 0.5 to 2 bar and 5 to 15 bar. This enables use under high inlet pressures of up to 40 bar.
For individual requirements, we offer the pressure reducers with an optional internal thread. Put your trust in GOETZE quality for efficient and reliable water pressure regulation in various environments.
