SELF-OPERATED DIFFERENTIAL PRESSURE AND FLOW REGULATORS TYPE ZSN 9
Regulators ZSN 9 are designed to control set-up differential pressure and flow rate in process installations, which are connected to regulator's valve outlet or inlet. Their main fields of application are heating and power installations, chemical and food process industries. Regulators are adapted to various working fluids, such as cold and hot water, steam, air and inert gas.
pressure difference control with flow limitation in installation that is connected in series to the controller.(housing on the supply or return side),
high control accuracy,
single ported with the pressure balanced plug,
