Boiler module IVAR.TV3-300 DN 50 with 3-way mixing valve, without circulation pump

Product detailed description

The boiler module IVAR.TV3-300 DN 50 (code IVA49043630) prepares and distributes heating water with mixing via a three-way valve. It is suitable for radiator, floor, and wall heating systems in circuits with a source whose output temperature varies significantly – typically a solid fuel boiler. It operates in closed hot water heating and cooling systems.

What the module contains

• Three-way mixing valve with a Kv value of 40
• Mounting location for a single or double circulation pump (pump is not part of the delivery)
• Inlet and return pipes with flanges DN 50 for connection to a horizontal distribution manifold
• Four flanged shut-off valves, check valve, and pressure ports
• Two filling/draining valves on the primary side
• Two temperature gauges 0–120 °C and sleeves for sensor Ø 6 mm
• Thermal insulation Trocellen C080 with thickness 30 mm (λ 0.034 W/m·K)

Performance and dimensions

The module can handle up to 225 kW at ΔT 20 K and up to 56 kW at ΔT 5 K, with a flow rate of up to 9700 l/h. The maximum operating pressure is 10 bar, temperature +100 °C. The steel body Fe EN 10217-1 has an epoxy powder surface finish, the axial distance of the connection is 300 mm, and the dimensions are 940 × 660 × 477 mm.

Valve actuator and installation

The actuator is ordered separately: IVAR.SERVOPOHON TV3 230 V with 3-point control (IVA20317350) or 24 V with 0–10 V control (IVA20317351). The module is mounted directly on the IVAR.HC-DN 50 manifold or via IVAR.CONNECTA reduction kits. The connecting material is part of the delivery. The valve is manufactured to the right; by rotating the valve and return pipe according to the instructions, a left version is created. Do not use lubricants with mineral oil for EPDM seals. The installation of the module and the mounting and wiring of the pump should be carried out by a qualified person. Before starting the system, flush it.

Technical parameters

Frequently asked questions

When to choose the mixed module IVAR.TV3-300 DN 50?
When you need to regulate the water temperature in the circuit – for example, for floor or wall heating or for a source with fluctuating temperature, such as a solid fuel boiler. The non-mixed module IVAR.S-300 is used for direct distribution without mixing.

Is the valve actuator included in the package?
No, the actuator IVAR.SERVOPOHON TV3 is ordered separately – in the version 230 V with 3-point control (IVA20317350) or 24 V with 0–10 V control (IVA20317351).

Is the circulation pump part of the module?
No, variant IVA49043630 is delivered without a pump and is prepared for a single or double circulation pump. The version with the DAB.EVOPLUS B 120/280.50 M pump has code IVA49043630DAB.

To which manifold is the module connected?
To the horizontal distribution manifold IVAR.HC-DN 50, directly or via IVAR.CONNECTA reduction kits. The connecting material including seals is included in the package.
