Valve for fan coil units ESBE VLG122 PN16 15-0.25 G 1/2 inch 21500100

Valves for fan coil units – precise control in heating and cooling systems

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

Construction and application

The VLG122 valve, made of dezincification resistant brass (DZR), features BSPP threaded connections with a diameter of 1/2 inch (DN15). Its design is based on the principle of a poppet valve, which ensures a linear flow characteristic. This means the valve responds proportionally to the control signal, allowing precise adjustment of system performance to current needs. A Kvs value of 0.25 m³/h indicates that this valve is ideal for installations with relatively low flow rates.

VLG100 valves are available in various versions – 2-way (VLG122), 3-way (VLG132) and 3-way with bypass (VLG142). All models are normally closed (NC) as standard, meaning the poppet blocks the flow in the initial position. Connection with the ESBE ALG400 actuator maintains the same characteristic – a normally closed circuit.

Key features and benefits

• Durability and resistance: Construction from CW617N brass guarantees corrosion resistance and long-term reliability.
• Precise control: Linear flow characteristic ensures accurate control of system performance.
• Compact dimensions: Allow easy installation even in tight spaces.
• Versatility: Availability in various versions (2-way, 3-way, 3-way with bypass) allows the valve to be adapted to specific installation needs.
• Safety: Maximum working pressure PN 16 and 0% leakage ensure safe operation.
• Ease of integration: Compatibility with ESBE ALG400 actuators simplifies the installation and configuration process.
• Wide temperature range: The ability to operate in a temperature range from +5°C to +95°C makes the valve suitable for a variety of applications.
• Compliance with standards: The valve meets the requirements of PED 2014/68/EU article 4.3, confirming its safety and quality.

The ESBE VLG122 valve is an optimal solution for installers looking for a reliable and precise control element in fan coil unit systems and for end users who value the comfort and energy efficiency of their heating and cooling installations.
