Angle radiator valve kfa² 1/2" model 750-160-15 for heating systems

The kfa² Angle radiator valve 1/2" model 750-160-15 is a compact plumbing fitting intended to connect radiators to central heating pipework at a 90° angle. Designed for standard 1/2" threaded radiator and inlet connections, the valve provides flow control and shutoff capability to enable radiator installation, isolation and maintenance without draining the entire heating system. The construction is suited to domestic and light commercial hydronic heating systems where a reliable angled connection is required.

Advantages

This angle radiator valve offers space-saving 90° orientation for installations where wall and pipe positions require an angled connection. It provides integrated shutoff functionality to isolate a single radiator for servicing or replacement. The valve is compatible with standard 1/2" threads, simplifying replacement of existing valves and reducing installation time. Its compact form factor supports neat, low-profile radiator connections and helps maintain consistent flow control within the heating circuit.

Suitable for

• Domestic radiator connections in apartments and houses
• Light commercial radiator installations and replacements
• Hydronic heating repairs and component upgrades
• Situations requiring a 90° connection between radiator and pipework

Key specifications

• Connection type: angled (90°) radiator valve
• Thread size compatibility: standard 1/2" radiator and inlet threads
• Function: flow control and shutoff for single-radiator isolation
• Application: central heating / hydronic systems for residential and light commercial use
• Form factor: compact, low-profile design for tight installation spaces

How to use

Prior to installation, ensure the heating circuit is isolated and any local water is drained or contained according to the system procedure. Fit the valve to the radiator inlet using the compatible 1/2" threaded connection and tighten to the manufacturer’s recommended torque, taking care to use suitable sealing materials where appropriate. Connect the valve to the supply or return pipework at the 90° orientation required, check alignment and secure unions or compression fittings as required. After installation, refill and vent the radiator, then operate the valve to check for correct flow control and leak-free joints.

Usage recommendations

Use the valve in closed or partially open positions for maintenance isolation. Inspect sealing surfaces and thread connections during routine servicing and replace seals or fittings if corrosion or wear is observed. For optimal performance, pair the valve with compatible radiators and pipework sized for 1/2" connections, and follow local plumbing codes for installation and pressure testing.
