ESBE VLE122 PN16 G1 1/2 DN25-10 regulating valve 21250900
Control valve for precise flow control
The ESBE VLE122 control valve is a reliable solution for mixing, switching and regulating flow in heating and cooling systems. Made of high-quality bronze (Rg 5), it ensures durability and corrosion resistance, which translates to a long service life even in demanding conditions. The VLE122 model with G1 1/2 (DN25) connections and a Kvs value of 10 is ideal for systems with medium flow.
Construction and practical application
The VLE122 valve is characterized by a constant percentage flow characteristic, which means that changing the position of the mushroom causes a proportional change in the medium flow. This allows for precise adjustment of the temperature in rooms or maintaining a constant temperature in a closed circuit. The use of a bronze valve makes it resistant to the action of heating water and glycol (up to 50%) and ethanol (up to 28%) mixtures. The ability to cooperate with ESBE actuators and controllers allows for automation of the regulation process and integration with smart home systems. This valve is used both in new installations and in the modernization of existing heating systems.
Key features and benefits
- Durability and reliability: Construction from Rg 5 bronze guarantees corrosion resistance and long-term use.
- Precise regulation: Constant percentage flow characteristic enables accurate temperature adjustment.
- Low leakage level: Ensures minimal energy loss and stable system operation. Leakage in relation to the Kvs value is only 0.02%.
- Versatility: Possibility of use with various ESBE actuators and controllers facilitates integration with existing systems.
- Media resistance: Adapted to work with heating water and glycol and ethanol mixtures.
- Safety: Pressure class PN 16 ensures safe operation with a maximum differential pressure of 6 bar in the open position.
- Easy installation: BSPP external threads facilitate connection to the installation. Connection length 1 is 52.5 mm, and connection length 2 is 39 mm. Valve stroke is 20 mm.
