​​​​​​​ Pressure independent balancing and control valve for modulating control The new uniquely shaped EQM characteristics provide highly precise temperature control. The valve is compatible with linear, proportional or 3-point actuators. A built-in differential pressure controller provides high control authority, control stability and automatic limitation of design flow. Measurement of flow and available pressure enables system optimisation and diagnostics.

Precise temperature control

Provide uniquely shaped EQM characteristic for best modulating control.

Precise control

Uniquely shaped EQM characteristic provides an up to 6 times larger operating stroke than linear valves.

Quick hydronic balancing

Automatic flow limitation when actuator is fully open protects entire system against overflows.

Easy troubleshooting

Flow and differential pressure measuring helps to reduce pump consumption and provides all necessary data for system diagnostics.

Technical description

Application:

Heating and cooling systems.

Functions:

Control EQM: DN 15-150 normal flow
Control LIN: DN 100-150 high flow

Differential pressure control
Measuring (ΔH, t, q)
Isolation (for use during system maintenance – see "Leakage rate")

Dimensions:

DN 15-150

Pressure class:

DN 15-50: PN 16
DN 65-150: Class 150

Differential pressure (ΔpV):

Max. differential pressure (ΔpVmax):
DN 15-32: 600 kPa = 6 bar
DN 15-25: 400 kPa = 4 bar*
DN 40-50: 400 kPa = 4 bar
DN 65-150: 800 kPa = 8 bar
Min. differential pressure (ΔpVmin):
DN 15-20: 15 kPa = 0.15 bar
DN 25-32: 23 kPa = 0.23 bar

DN 100-125 HF: 55 kPa = 0.55 bar
DN 150 HF: 60 kPa = 0.60 bar
(Valid for maximum setting, fully open. Other settings will require lower differential pressure, check with the software HySelect.)

ΔpVmax = The maximum allowed pressure drop over the valve to fulfill all stated performances.

ΔpVmin = The minimum recommended pressure drop over the valve, for proper differential pressure control.
