Regulators ZSN2 are used to control preset pressure in process installations connected to regulator valve outlet. Regulators are applied in heating systems, in industrial processes with cold and hot water, steam, air and nonfl ammable gases. Using with other media subject to consulting with manufacturer. CONSTRUCTION:
Regulator comprises three, temporary fastened main units: valve (01), actuator (02) and booster (06). Regulator valve single-ported with balanced plug.
