Angle Radiator Supply Valve Calido Eskimos 1/2" (CA/ZG-ZK1/2) - Heating Valve

Calido Eskimos angle radiator supply valve CA/ZG-ZK1/2 is an angled 1/2" connection valve designed for hot-water central heating systems. It is intended to be fitted where the supply pipe meets the radiator at a 90° angle, providing controlled delivery of heating medium to the radiator. The valve is suitable for domestic and light commercial radiator installations and is built to integrate with standard 1/2" threaded radiator inlets.

Advantages

The angle radiator supply valve offers reliable flow control and a compact design that facilitates installation in tight spaces. Its 90° configuration reduces the need for additional pipe fittings and allows a neat finish at the radiator inlet. The valve is compatible with common radiator fittings and supports straightforward maintenance and replacement.

Suitable for

• Domestic hot-water central heating radiators with 1/2" threaded inlets
• Light commercial radiator installations requiring angled supply connections
• Renovation projects where existing pipework approaches the radiator at a right angle
• Situations where a compact, space-saving valve body is needed

When it may not be suitable

This valve is designed specifically for 1/2" threaded radiator connections and for use in hot-water central heating systems; it may not be suitable for radiator systems that require integrated thermostatic control or for systems using larger or metric-different connection sizes. It is not intended for use with steam heating systems or for applications involving aggressive fluids or temperatures outside typical domestic heating ranges.

Key specifications

• Connection type: angled 90° supply valve
• Thread size: 1/2"
• Application: hot-water central heating radiators
• Installation orientation: inlet at right angle to radiator inlet
• Typical materials: corrosion-resistant metals suitable for heating systems

How to use

Shut down the heating system and drain the section of pipework before starting installation. Fit the valve to the radiator inlet using the 1/2" threaded connection, ensuring appropriate sealing (e.g., PTFE tape or sealant) on the male thread if required. Align the valve so the supply pipe enters at 90° and tighten to the manufacturer’s recommended torque. After installation, refill and vent the radiator, then check for leaks and correct operation of the valve.

What to consider before purchase

• Confirm radiator inlet thread size is 1/2" and compatible with an angled valve
• Verify that a non-thermostatic supply valve meets your control needs or if a thermostatic valve is required
• Check available space behind and around the radiator to accommodate a 90° valve body
• Ensure materials and construction are suitable for your system's operating pressure and water quality

Usage recommendations

Use the valve as part of routine radiator maintenance and replacement work. When installing, follow local plumbing codes and use appropriate sealing and tightening practices. If thermostat control is needed, pair this supply valve with a compatible thermostatic head or consider replacing with a combined thermostatic angled valve.
