Pressure regulator ZSN (self-operated regulator)

Series ZSN pressure regulators are used for flow control in heating systems and in industrial and process technology of water and steam (max. 200°C) and non-flammable gases (max. 80°C) They operate through pre-set downstream pressure (ZSN 1) or upstream pressure (ZSN 3) without auxiliary power (controlled by the transported media).

Nominal sizes: DN 15, 20; 25; 32; 40; 50; 65; 80; 100
Nominal pressure: PN16- PN40 or ANSI 150; 300
Face to face DIN EN 60534-3-1 or ANSI B16.10
Leakage classes (according to DIN EN 60534-4): IV (<0,01% Kvs); VI (bubble-tight)
