District heating – heat exchanger for heating
Typical for applications are: slow changes in heating demand; high operating pressures and temperatures; safe and reliable operation even under extreme operating conditions is essential; fail-safe function is required; 2-port flanged or threaded valves; 3-position control.
The proposed combinations vary in: control accuracy; plant operating conditions, amount of flow volume.
High performance, high control quality solution
Stroke valves (20/40 mm stroke) with selectable flow characteristic; fine gradual increments in kVS-values; excellent flow control in heating circuits; VVF52 suitable for operation in PN 25 plants up to 180°C with medium volumetric flows VVF45 suitable for operation in PN 16 plants up to 180°C with large volumetric flows offering for different PN classes and control signals.
