Belimo EP100F+MP – EPIV control valve
The device combines a characterised control ball valve, a measuring tube with a flow meter and an actuator. It measures the flow rate and adjusts the valve position by comparing the measured value with the setpoint. It is designed for analogue control of water flow in air handling unit circuits and heating systems.
Key features and specifications
- 2-way design; DN 100, PN 16 flanged connection.
- Nominal flow rate V'nom 20 l/s; adjustable V'max 30...100% V'nom.
- Ultrasonic flow measurement and electronic flow control independent of pressure changes.
- Power supply AC/DC 24 V; MP-Bus communication or analogue control with an operating range Y 2...10 V.
- Medium: water or water with a maximum of 50% by volume glycol; medium temperature -10...120°C [14...248°F].
- Pressure difference ∆pmax 340 kPa; closing pressure ∆ps 690 kPa.
- Equal-percentage flow characteristic (VDI/VDE 2173), with the option to switch to linear (VDI/VDE 2173).
- Permissible leakage: bubble-tight, leakage rate class A (EN 12266-1).
- Enclosure protection rating IEC/EN: IP54.
Permitted mounting position: from vertical to horizontal relative to the spindle; installation with the axis pointing downwards is not permitted. The flow direction must match the arrow on the housing. A straight inlet section of at least 5 x DN is required upstream of the flow sensor.
