Angle radiator valve Oventrop RFV9 DN15 left-hand, connection K (1185004)

The Oventrop RFV9 DN15 left-hand angle radiator valve with connection K is designed for precise flow control of hot-water radiators in central heating systems. The compact angle body with DN15 (⅝") dimensions and left-hand orientation allows installation where pipework and radiator inlet positions require a left-sided connection. The valve is suitable for residential and light commercial radiators and is compatible with standard radiator fittings, providing dependable regulation of supply flow to ensure balanced heating performance.

Advantages

This angle radiator valve offers a compact design that saves space at the radiator inlet and simplifies installation in tight areas. The left-hand configuration ensures correct alignment with left-sided pipework without the need for additional adapters. Built for use in hot-water heating systems, the valve enables accurate flow regulation to help maintain stable room temperatures and can be integrated with thermostatic heads or manual actuators where required.

Suitable for

• Domestic hot-water radiator installations with left-hand inlet connections
• Light commercial heating systems requiring DN15 angle valves
• Replacement of standard radiator valves with left-oriented piping
• Systems where compact valve bodies are needed for limited space

Key specifications

• Valve type: angle radiator valve, left-hand orientation
• Nominal size: DN15 (⅝")
• Connection style: K-type connection for standard radiator fittings
• Application: hot-water central heating radiators
• Control compatibility: suitable for use with thermostatic heads or manual actuators
• Body form: compact angle design for space-saving installation

How to use

Shut down the heating system and allow the radiator and pipework to cool before starting installation. Fit the valve to the radiator inlet using the appropriate connection fittings and ensure the left-hand orientation matches the system pipework. Tighten connections to the manufacturer-recommended torque values and check for leaks. If a thermostatic head or actuator is to be fitted, mount it on the valve according to the control device instructions and set initial flow or temperature settings before returning the system to operation. After commissioning, verify correct flow and adjust the valve or controller to balance radiators across the system.

Usage recommendations

For reliable long-term performance, use the valve in systems with water quality and operating parameters compatible with standard heating system practice. Regularly inspect connections for leaks and check control fittings such as thermostatic heads and actuators for proper operation. When replacing an existing valve, confirm left-hand alignment and DN15 sizing to ensure direct compatibility and minimise installation work.
