Typical for the application are: fast 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 valves; 0-10 V or 3-position control signal.
The proposed combinations vary in: control accuracy; plant operating conditions; control signals.
PN 16 magnetic flanged valves with integrated actuator and selectable valve characteristic; fast and high-precision flow control for operation up to 180°C and steam pressure up to 9 bar; opening without inlet jump; excellent for minimum controllable load; designed specifically for district heating applications; excellent performance with compact heat exchangers, where heat transmission is considerably faster.
PN 25 stroke valves (20/40 mm stroke) with selectable flow characteristic; fine gradual increments in kVS-values; excellent flow control in heating circuits for operation up to 180°C or steam pressure up to 6 bar; 0-10 V or 3-position control signal.
