Radiator Valve FERRO ZG2LY straight 1/2" — manual heating valve, brass connection

Straight radiator valve FERRO ZG2LY 1/2" is a manual heating valve designed for controlling hot-water flow to radiators in standard central heating systems. The compact straight-body design with a brass connection provides durable sealing and broad compatibility with common radiator fittings. This valve is intended for installation where simple, reliable manual regulation of radiator flow is required in residential and light commercial applications.

Advantages

The brass connection ensures corrosion resistance and long service life under normal heating system conditions. The straight configuration simplifies installation on radiators with inline inlet connections and reduces the number of fittings required. Manual operation offers straightforward, low-maintenance control without the need for power supply or electronic components. The construction is compatible with standard 1/2" radiator fittings, enabling replacement or retrofit of existing manual valves.

Suitable for

• Domestic hot-water central heating radiators
• Small commercial or office radiator circuits
• Replacement of existing straight manual radiator valves
• Retrofit projects where a compact straight valve is needed

Key specifications

• Connection type: straight inline
• Connection size: 1/2"
• Material: brass connection with metal valve body
• Operation: manual control
• Application: hot-water central heating systems
• Typical mounting: radiator inlet with compatible fittings

How to use

Isolate the heating circuit and drain the radiator before removing the old valve. Fit the FERRO straight valve to the radiator inlet, ensuring the 1/2" connection is tightened to the correct torque and sealed according to plumbing best practices. After installation, refill and vent the radiator to remove air pockets, then check for leaks while the system is at operating pressure and temperature. Operate the valve manually to regulate flow; avoid forcing the valve beyond its normal travel to prevent damage.

Usage recommendations

Use appropriate thread sealant or tape on threaded joints and verify compatibility with the radiator tailpiece and pipework. Perform leak checks after thermal cycling and follow local plumbing codes for installation and maintenance. For systems requiring automatic temperature control, consider pairing this manual valve with a compatible thermostatic head or using dedicated thermostatic valves.
