Balancing valve flanged Hydrocontrol VFC, grey cast iron, PN 16, DN 25 1062647

Balancing valve for precise flow control

The Hydrocontrol VFC flanged balancing valve is a reliable solution for flow regulation in central heating and domestic hot water systems. Made of durable grey cast iron and designed to operate at a pressure of PN 16, it ensures long-lasting and trouble-free operation. Its design, compliant with DIN EN 558-1 (series 1) and DIN EN 1092-2 (flanges), guarantees easy installation and integration with existing systems.

Construction and practical application

Hydrocontrol VFC is designed for precise setting and maintaining the desired flow parameters in individual circuits of the installation. Equipped with a clear, stepless pre-setting scale, it allows for optimization of the heating system efficiency and reduction of operating costs. The Kvs value of 8.38 provides adequate flow rate for installations with a nominal diameter of DN 25. Integrated measuring ports (G1/4") facilitate system monitoring and diagnostics. This valve is particularly useful in CH installations, where balancing circuits is crucial for ensuring thermal comfort in all rooms.

Key features and benefits for installers and users

• Durable construction: The body made of cast iron GG25 (GJL-250) guarantees resistance to corrosion and mechanical damage, which translates into a long service life.
• Precise regulation: Stepless pre-setting allows for accurate adjustment of the flow rate to the needs of a specific heating circuit or domestic hot water installation.
• Easy reading: The knob with a clear scale makes it easy to set the desired flow value, and the ability to seal the setting protects against unauthorized changes.
• Complete set: The valve has a set of two G1/4" measuring ports mounted, eliminating the need to purchase additional elements.
• Versatility: Designed for use in central heating (CH) and domestic hot water installations (excluding drinking water).
• Compliance with standards: Meets the requirements of DIN EN 558-1 and DIN EN 1092-2 standards, ensuring compatibility with other installation elements.
• High quality workmanship: The head made of bronze, spindle and mushroom made of dezincification-resistant brass and PTFE seal ensure reliable operation for a long time.
• Maintenance-free: Double O-ring made of EPDM ensures spindle tightness without the need for regular maintenance.
