## Summary description

Perfexim radiator supply valve, straight design with 1/2" connection (model 20-030-0000-000). Intended for use in central heating radiator installations to control inlet flow. Suitable for standard radiator fittings with 1/2" threads, used in residential and commercial heating systems to enable on/off and flow adjustment at the radiator inlet.

## Long description

Perfexim radiator supply valve 1/2" (straight) is a compact control fitting designed for the inlet of central heating radiators. The valve provides on/off function and allows adjustment of flow to the radiator. Its straight-body design with 1/2" threaded connections is compatible with standard radiator fittings used in residential and commercial heating circuits.
Advantages
The valve has a simple straight design that eases installation on radiators with 1/2" threads and reduces the need for additional adapters. It offers reliable flow control at the radiator inlet, enabling precise balancing of individual radiators. The compact form factor saves space in tight installation areas and the construction is suitable for routine maintenance or replacement of existing inlet valves.
Suitable for
 Replacement or installation of 1/2" radiator inlet valves in central heating systems
 Balancing flow between radiators in residential buildings
 Use in commercial or small industrial heating circuits with standard 1/2" fittings
 Situations requiring a straight inline valve where space behind the radiator is limited
Key specifications
 Connection type: straight inline with 1/2" threaded connections
 Function: on/off and adjustable flow control at radiator inlet
 Application: central heating radiator inlet
 Compatibility: standard 1/2" radiator fittings for residential and commercial systems
 Design: compact, space-saving straight body
How to use
Shut down the heating system and isolate the radiator before replacing or installing the valve. Fit the valve to the radiator inlet using the 1/2" threaded connection, ensuring appropriate sealing (thread tape or joint compound) as required by local practice. Tighten connections to the recommended torque for the fittings used, refill and vent the radiator to remove air, then check for leaks. Use the valve stem to open, close, or throttle flow to balance radiator temperature as needed.
Usage recommendations
For reliable operation, perform periodic visual checks for leaks and ensure the valve operates smoothly. When balancing a heating system, adjust valves gradually and allow the system to stabilize between adjustments. If corrosion or wear is evident, replace the valve to maintain system performance and prevent leaks.
