Control valve ESBE VLA131 PN16 RP1/2 DN15-1.6 21150900

Control Valve for Precise Flow Regulation

The ESBE VLA131 control valve is a component designed for heating and cooling systems requiring precise flow regulation. Manufactured from high-quality ductile iron, it ensures durability and reliable operation even under demanding conditions. The VLA131 is a 3-way valve ideal for mixing and flow control, operating at pressures up to 16 bar.

Construction and Application

The VLA131 valve features internally threaded connections (Rp ½"), facilitating easy installation and integration into existing systems. Its constant-percentage characteristic ensures stable performance and precise flow control. A Kvs value of 1.6 guarantees suitable flow capacity for nominal diameter DN 15. This valve works seamlessly with ESBE actuators and controllers, forming a complete regulation system.

Applications include:

• Heating systems with 3-way control
• Cooling systems with 3-way control
• Heating systems with circulating pumps
• Cooling systems with circulating pumps
• Installations using water-glycol mixtures (up to 50%) and water-ethanol mixtures (up to 28%).
