ESBE VLA121 PN16 RP1/2 DN15-4.0 regulating valve 21150300

ESBE VLA121 regulating valve is a component designed for precise flow control in heating and cooling systems. It belongs to the VLA100 series, which includes both 2- and 3-way models, designed to operate at pressures up to 16 bar. Made of high-quality spheroidal graphite cast iron, it guarantees durability and reliability even in demanding conditions.

The VLA121 valve with a nominal diameter of DN15 and a Kvs value of 4, is an ideal solution for regulating flow in circuits with lower performance. Its design based on a constant percentage characteristic ensures stable operation and precise setting of the desired flow. RP1/2 connections facilitate installation and integration with the existing system.

Design and application

The VLA100 series has been designed to work with ESBE actuators and controllers, allowing for the creation of comprehensive control systems. These valves are used in heating, cooling systems, and mixing applications where precise temperature and flow control is required. Thanks to the low leakage rate, the valve minimizes energy losses and ensures optimal system efficiency. The stroke length of 20 mm allows for accurate adjustment of the flow to current needs.

Why choose the ESBE VLA121 valve?

• Durability: Construction from spheroidal graphite cast iron provides corrosion resistance and long life.
• Precision: Constant percentage characteristic guarantees stable flow regulation.
• Compatibility: Ideally cooperates with ESBE actuators and controllers, creating an integrated control system.
• Versatility: Suitable for use in heating, cooling and mixing systems.
• Low leakage rate: Minimizes energy losses and increases system efficiency.
• Easy installation: RP1/2 connections simplify installation.
• Temperature resistance: Designed to operate in a temperature range from -20°C to +130°C.
• Safety: Maximum differential pressure in the open position is 6 bar, ensuring safe operation of the installation.

The VLA121 valve is also characterized by compact dimensions – connection length 1 is 42.5 mm, and connection length 2 is 38 mm – which facilitates installation even in tight spaces. Surface coating provides additional protection against corrosion and external factors.
