Valve for fan coil units ESBE VLG122 PN16 15-1.0 G 1/2 inch 21500400

Valve for fan coil units ESBE VLG122 – precise flow control

The ESBE VLG122 valve is a reliable solution for controlling the flow of heating or cooling medium in heating, air conditioning and, above all, fan coil unit installations. Its compact design makes it easy to install even in tight spaces, for example directly on the connections of heat exchangers. Made of dezincification-resistant brass (DZR), it ensures long-lasting and trouble-free operation.

The VLG122 valve is designed to work with ALG400 series thermoelectric actuators, creating a simple to install and efficient control system. Thanks to the threaded ring nut, connecting the actuator to the valve is quick and convenient. This model is a two-way, normally closed (NC) valve, which means that in the default position, the plunger blocks the flow of medium.

Construction and application

This valve, with a nominal diameter of DN15 and a Kvs value of 1, is characterized by a linear flow characteristic. This means that the medium flow changes proportionally to the position of the valve plunger. This is particularly important in precise temperature control systems in fan coil units. The use of CW617N brass guarantees corrosion resistance and mechanical strength. BSPP (G ½ inch) threads ensure a tight connection with the installation.

Advantages and benefits

• Compact dimensions: Allow installation in limited space, which is crucial for installations in existing buildings or where space is limited.
• High-quality materials: Dezincification-resistant brass (DZR) provides long-lasting protection against corrosion and extends the valve's lifespan.
• Simple installation: Threaded connection with the ALG400 actuator makes installation easier and faster.
• Precise control: Linear flow characteristic allows for accurate temperature control in the fan coil unit.
• Versatility: Suitable for use in both heating and air conditioning installations.
• Safety: Pressure class PN 16 guarantees safe operation under typical operating conditions.
• 0% leakage: Ensures no loss of working medium, which translates to energy efficiency of the system.

The ESBE VLG122 valve is a solid choice for both professional installers looking for a reliable component and end-users who value comfort and precise temperature control in their home or office.
