3-Way Set: Vrg131Dn25+Ara661,230V,Kvs10 13022400

Mixing valve with actuator – reliable temperature control

This set combines precision and reliability. The VRG131DN25 mixing valve, in combination with the ARA661 actuator, creates a complete solution for temperature regulation in heating and cooling systems. The compact design simplifies installation, and the matched components guarantee optimal cooperation. The set is ideal for both professional installers and end-users looking for an effective way to control temperature.

Construction and application

The set consists of a three-way mixing valve VRG131DN25 and an ARA661 actuator powered by 230V AC. The valve is made of dezincification resistant brass (DZR), which ensures its durability and corrosion resistance. Designed for a nominal diameter of DN25 (1 inch), it is characterized by a Kvs flow rate of 10. The actuator is controlled by a three-point signal, which allows for precise adjustment of the valve position and control of the medium flow. The set is used in underfloor heating systems, radiator installations, and cooling systems requiring precise temperature regulation.

Key features and benefits

• High regulation accuracy: Linear flow characteristic ensures accurate temperature setting.

• Low leakage level: Leakage at the level of 0.05% of the Kvs value minimizes energy losses and ensures stable system operation.

• Durable construction: Dezincification resistant brass (DZR) guarantees a long valve life, even in harsh operating conditions.

• Easy installation: Compact design simplifies installation in tight spaces.

• Versatility: Manual control option (thanks to manual override) and automatic control (three-point signal) increase application flexibility.

• Wide temperature range: Operation in ambient temperature range from -5 to 55°C allows the set to be used in various climatic conditions.

• Safety: Protection class IP41 provides protection against access to hazardous parts and against environmental influences.

• Pressure class PN 10: Ensures safe operation in typical heating and cooling installations.

• Minimal energy consumption: Power consumption at 5 VA makes the set energy-efficient.
