Type 2488 N/5857 Pressure-independent Control Valve

Type 2488 N/5857 Pressure-independent Control Valve

Application Globe valve DN 15. Nominal pressure PN 10. Flow set point ranges from 0.3 to 1.0 m³/h or 0.1 to 0.5 m³/h with a differential pressure at the restriction of 0.2 bar. Suitable for treated water up to 110 °C and non-flammable gases up to 80 °C.

Pressure-independen control valve (PICV) for flow rate control in heat supply networks, combined with an electric actuator to apply a control signal of an electric control device.

Particularly suitable for local heat supply and large heating networks.

The valve closes when the flow rate or the output signal of the electric control device increases.

The combined regulator consists of a valve with integrated diaphragm actuator and an additional Type 5857 Electric Actuator

Special features 

. Low-maintenance proportional regulators requiring no auxiliary energy 

. Single-seated globe valve • Compact design 

.Control quality independent of the network differential pressure, for example for temperature control with weather-compensated control equipment 

. Suitable for treated circuit water
