ESBE VLA121 PN16 RP1/2 DN15-2.5 regulating valve 21150200

ESBE VLA121 regulating valve is an element designed for precise flow control in heating and cooling systems. Made of high-quality spheroidal graphite cast iron, it ensures durability and reliability even in demanding conditions. This model, with Rp ½” connections and a DN15 diameter, is characterized by high controllability – a Kvs value of 2.5 allows for effective adjustment of the flow to current needs.

The VLA121 valve is compatible with ESBE actuators and controllers, making it easy to integrate with modern building management systems. Its design based on a constant percentage characteristic ensures stable operation and precise maintenance of the set temperature. Thanks to the low internal leakage rate, the valve minimizes energy losses and optimizes operating costs.

Construction features and application:

• 2-way valve, ideal for regulating flow in one direction.
• Made of spheroidal graphite cast iron – a material resistant to corrosion and high pressure.
• Rp ½” (DN15) connections facilitate installation in standard installations.
• Maximum working pressure PN 16 (6 bar) – ensures safe use.
• Stroke length of 20 mm allows for precise flow adjustment.
• Surface coating provides increased resistance to external factors.
• Designed for operation with heating water and water-glycol mixtures (up to 50%) and water-ethanol mixtures (up to 28%).
• Ideally suited for underfloor heating, radiator and air conditioning systems.

The VLA121 valve is a solid solution for both professional installers and end-users looking for a reliable element to regulate flow in their installations. Its versatility and ease of integration with existing systems make it a popular choice for modernization and construction of new heating and cooling installations. The Kvs value of 2.5 makes this valve particularly well-suited for applications requiring precise flow control at relatively low values.
