Application: Regulators for district heating systems, heat generators, heat exchangers and other HVAC and industrial applications. Temperature set points from 0 to 150 °C · Valves G ½ to 1 · DN 15 to 50 · Pressure rating PN 25 · Suitable for liquids up to 150 °C, Steam up to  200 °C and non-flammable gases up to 80 °C · The valves close as the temperature rises

The valve opens or closes when the temperature rises.

• Low-maintenance proportional regulators requiring no auxiliary energy
• Temperature sensor suitable for installation in any desired position and for operation at high excess temperatures (50 K above the set point), designed for operating pressures up to 40 bar
• Globe valves with plug balanced by a piston
• Particularly suitable for district heating supply networks
• Suitable for gases and liquids
• Special version: fast-responding thermostats for instantaneous water heater
