ESBE VLE122 PN16 G1 DN15-4.0 regulating valve 21250700

Control valve for precise flow control

The ESBE VLE122 control valve is a reliable solution for heating and cooling systems, designed for mixing, switching (at a pressure difference below 50 kPa), and flow regulation. Made of high-quality bronze (Rg 5), it ensures durability and corrosion resistance, translating into a long service life even in demanding conditions. This model, with a nominal diameter of DN15 and a Kvs value of 4, is ideal for precise control of liquid flow in installations.

Design and application

The VLE series valves are characterized by their versatility – they are available in 2-way and 3-way versions, in a wide range of sizes (DN 15-50). Equipped with external cylindrical gas threads (BSPP) with a length of 50 mm (connection 1) and 36 mm (connection 2), they allow for easy installation and integration with existing installations. Thanks to the constant percentage flow characteristic, the valve provides stable regulation regardless of pressure changes. This is particularly important in systems powered by pumps with variable performance. The VLE122 valve works perfectly with ESBE actuators and controllers, creating comprehensive and efficient heating solutions.

Key features and benefits

• High quality workmanship: Bronze construction guarantees corrosion resistance and long-term use.
• Precise regulation: A Kvs value of 4 allows for accurate adjustment of the flow to the needs of the installation.
• Low pressure drop: The maximum pressure difference in the open position is 6 bar, which minimizes energy losses.
• Low leakage: Leakage at only 0.02% of the Kvs value ensures minimal leaks and stable system operation.
• Versatility: Can be used in heating and cooling systems and with various ESBE actuators.
• Easy installation: Standard BSPP threads facilitate integration with existing installations.
• Durability: Solid construction and high-quality materials ensure reliable operation for a long time.
• Stroke length: The valve stroke is 20 mm, allowing for precise setting of the desired flow value.
