IMI TA balancing valve DN25 with 3/4" drain, model 52851625

IMI TA balancing valve DN25 with 3/4" drain, model 52851625 is a hydraulic balancing component designed for heating and cooling systems that require accurate flow regulation. The valve has a DN25 connection size and an integrated 3/4" drain connection that supports draining and venting during commissioning and maintenance. It is intended to ensure correct flow distribution across branches of a hydraulic network, helping maintain stable operation and efficient heat transfer.

Advantages

The valve provides precise flow control and repeatable adjustment to achieve hydraulic balance in pipe networks. Its integrated drain connection simplifies venting and system emptying procedures without the need for additional fittings. The compact design and standardized DN25 port make installation straightforward in typical residential or commercial heating and cooling loops. Materials and construction are chosen to resist common system conditions and to enable routine maintenance operations.

Suitable for

• Commissioning and balancing of hydronic heating systems
• Balancing chilled water and cooling circuits
• Hydraulic balancing of radiator and fan coil branches
• Maintenance tasks requiring controlled draining and venting

Key specifications

• Nominal connection size: DN25
• Integrated drain connection size: 3/4"
• Function: manual hydraulic balancing and flow regulation
• Application: heating and cooling (hydronic) systems
• Mounting: inline installation in pipework

How to use

Install the balancing valve inline at the designated branch point following the system layout and accepted piping practices. Use the valve’s adjustment mechanism to set the required flow rate during system commissioning, measuring differential pressure or flow as necessary with appropriate instruments. The integrated 3/4" drain connection is used to vent air or to drain the section for maintenance; connect suitable hoses or fittings before opening. After adjustment, secure the setting to prevent unintended changes and verify balanced operation across the system.

Usage recommendations

Perform commissioning with calibrated measurement tools and follow manufacturer guidance for incremental adjustments. When draining or venting through the integrated connection, ensure downstream containment and environmental safety. Schedule periodic inspections to confirm settings and check for leaks or wear.
