Valve for fan coil units ESBE VLG122 PN16 15-0.6 G 1/2 inch 21500300

Valves for fan coil units – precise flow control

ESBE VLG100 series valves are reliable components designed to control the flow of heating or cooling medium in heating, air conditioning and, above all, fan coil unit installations. Their compact design makes them easy to install even in tight spaces, for example directly on exchanger connections. These valves are particularly recommended for use with ESBE ALG400 electric actuators, creating a simple and effective control system.

Construction and application

The VLG122 valve we offer is a 2-way model with a G ½ inch threaded connection. Made of dezincification resistant brass (DZR), it ensures durability and corrosion resistance. The linear flow characteristic means that the valve responds proportionally to changes in the control signal, which translates into precise temperature control in the room. This means that both installers and end-users can count on stable thermal comfort conditions.

VLG100 valves are widely used in heating and cooling systems where precise control of medium flow is required. They are ideal for:

• Fan coil units
• Heating installations
• Air conditioning systems
• Applications requiring precise temperature regulation

Key features and benefits

• Durability and resistance: Construction from CW617N brass guarantees long life and corrosion resistance.
• Compact dimensions: Facilitate installation in limited spaces.
• Precise regulation: Linear flow characteristic ensures accurate temperature control.
• Ease of integration: Compatibility with ESBE ALG400 actuators simplifies installation and system configuration.
• High tightness: Ensures minimal loss of working medium (leakage 0%).
• Versatility: Can be used in water installations as well as with glycol (up to 50%) and ethanol (up to 28%) mixtures.
• Safety: Compliance with PN 16 standard ensures safe system operation at maximum static pressure.
• Efficiency: Kvs value at 0.63 provides optimal flow with low pressure drop.

The VLG122 valve is characterized by a stroke of 2.5 mm and a maximum differential pressure in the open position of 3 bar. The connection length is 26 mm and 23 mm respectively, which facilitates integration with the existing installation. The use of EPDM seals ensures reliability and long-lasting tightness of the connections.
