ESBE VLE122 PN16 G2 DN32-16 regulating valve 21251000

Control valve for precise flow control

The ESBE VLE122 control valve is a reliable solution for precise flow control 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. Model VLE122 with threaded connections G2 and a diameter of DN32 is characterized by high efficiency – a Kvs coefficient of 16 guarantees an effective flow of the medium.

Construction and practical application

The VLE122 valve belongs to the VLE series, including 2- and 3-way valves designed for mixing, switching (with a pressure difference below 50 kPa), and flow regulation. Its construction based on a constant percentage characteristic ensures stable operation and precise setting of the desired flow. This makes it ideal for underfloor heating systems, fan coil units, and cooling applications. The valve is compatible with ESBE actuators and controllers, enabling easy integration with advanced building automation systems.

Key features and benefits

• High quality workmanship: Bronze construction (Rg 5) guarantees corrosion resistance and long-term reliability.
• Precise regulation: Constant percentage characteristic ensures stable flow and accurate setting of operating parameters.
• Low leakage level: Leakage at only 0.02% of the Kvs value minimizes energy losses and ensures system efficiency.
• Versatile application: Can be used in heating and cooling systems.
• Easy integration: Compatibility with ESBE actuators and controllers simplifies installation and configuration.
• Pressure resistance: Pressure class PN 16 allows operation in installations with a maximum working pressure of 16 bar.
• Stroke length: Valve stroke length of 20 mm allows precise adjustment of the flow to current needs.
• Maximum differential pressure: The valve can operate at a maximum differential pressure of 6 bar in the open position, ensuring stable system operation.
• Standard connections: External tapered gas threads (BSPP) facilitate connection to the existing installation. Connection lengths are 52.5 mm and 39 mm, respectively.
