Verified by manufacturer 3 days ago
DN15
DN15
Flow regulator with electric actuator, DN15–50 with threaded ends. Low-maintenance, medium-controlled proportional regulators requiring no auxiliary energy.
Application
Flow rate control in district heating systems or extended heating or cooling networks.
For use with water and other liquids, provided these do not cause the materials used to corrode. Suitable for treated water up to 150°C.
Description
Flow regulator with electric actuator, DN15–50. Low-maintenance, medium-controlled proportional regulators requiring no auxiliary energy.
Features and benefits:
- Closes when the flow rate rises or when the output signal issued by the electric control device increases.
- Compact design.
- Consists of a valve, diaphragm actuator and an adjustable orifice (with an electric actuator attached to it).
- A maximum flow rate can also be adjusted mechanically at the orifice.
- Valve 2488: Compact design, single-seated valve with balanced plug.
- Threaded end connections.
- Globe valve, size DN15, DN20, DN25, DN32, DN 40 or DN50.
- Pressure rating PN16 or PN25.
- Flow set point ranges from 0.03 to 15 m³/h.
Flow regulator with thermostat connection also available (Type 2489), consult manufacturer for details.
