ESBE VLE122 PN16 G1 DN15-2.5 regulating valve 21250600

Flow control valve for precise flow control

The ESBE VLE122 flow 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, resulting in a long service life even in demanding conditions. Model VLE122 with BSPP (G1) threaded connections and a nominal diameter of DN15, is characterized by a Kvs flow rate of 2.5, making it an ideal choice for systems with medium flow.

Design and application

The VLE122 valve belongs to the VLE series, which includes 2- and 3-way valves designed for mixing, switching (with a pressure difference below 50 kPa), and flow control. Thanks to its design, this valve works perfectly with ESBE actuators and controllers, allowing the creation of advanced control systems. Its constant percentage flow characteristic ensures stable operation and precise setting of the desired medium flow. The use of bronze as a construction material guarantees compatibility with heating water and water-glycol (up to 50%) and water-ethanol (up to 28%) mixtures.

Key features and benefits

• High regulation accuracy: Ensures optimal operating parameters of the heating or cooling installation.
• Durability and reliability: Rg 5 bronze construction guarantees corrosion resistance and long service life.
• Low leakage rate: Minimizes energy losses and ensures system efficiency. Leakage in relation to the Kvs value is only 0.02%.
• Versatile application: Can be used in heating, cooling installations and mixing systems.
• Compatibility with ESBE actuators: Enables integration with advanced control systems.
• Appropriate operating parameters: The maximum differential pressure in the open position is 6 bar, and the medium temperature can range from -20°C to +150°C.
• Easy installation: BSPP (G1) threaded connections facilitate installation in existing systems. Connection length 1 is 50 mm, and connection length 2 is 36 mm. Valve stroke is 20 mm.
