ESBE VLE122 PN16 G2 3/4 DN50-38 regulating valve 21251200

Control valve for precise flow control

The ESBE VLE122 control valve is a reliable solution for heating and cooling systems, designed for precise flow control of the medium. Made of high-quality bronze (Rg 5), it ensures durability and corrosion resistance, translating into a long service life even in demanding conditions. Model VLE122 with external threaded connections (BSPP) with a diameter of 3/4 inch (DN50) and a Kvs value of 38, is ideal for applications requiring a constant percentage flow characteristic.

Construction and application in installations

Valves from the VLE series are versatile devices that find application in mixing, switching (with a pressure difference below 50 kPa), and flow regulation. Thanks to the pressure class PN 16, they can operate in installations with a maximum working pressure of 16 bar. The valve stroke length is 20 mm, allowing for accurate adjustment of the flow to the system's needs. It provides minimal leakage at a level of 0.02% of the Kvs value, which guarantees efficient operation and minimizes energy losses. This valve is compatible with ESBE actuators and controllers, making it easy to integrate with modern building management systems.
