Direct acting pressure regulator type ZSN 5

Regulators are used to control preset pressure in process installations connected to regulator valve outlet.

They are used in district heating systems, industrial processes in water to control flow of cold and hot water, steam, air and non-combustible gases. Using with other media subject to consulting with manufacturer. We can adjust the control valve to match your individual needs.
