## Long description

DANFOSS RLV-KB 1/2 angle valve (model 003L0394) is a compact valve designed for hydronic heating applications. Intended for 1/2" pipe connections, the valve provides reliable flow control and shut-off capability for radiator and heating circuits. Its angled body makes it suitable for tight installation spaces and for mounting on either supply or return lines in residential and commercial heating systems. The design permits isolation of individual radiators or sections of a circuit during maintenance or repairs while maintaining a compact footprint.
Advantages
The valve offers precise flow control and an integrated shut-off function in a compact, angled form factor. Its construction is suitable for common hydronic heating environments and supports straightforward installation on 1/2" fittings. Because the valve can be mounted on supply or return lines, it provides flexibility in system layout and simplifies maintenance tasks by allowing isolation of components without draining the entire system.
Suitable for
 Residential radiator connections with 1/2" pipe fittings
 Commercial heating circuits requiring compact shut-off and regulation
 Situations with limited installation space where an angled valve is required
 Installation on supply or return lines to isolate sections for maintenance
Key specifications
 Connection size: 1/2" thread compatible with standard radiator fittings
 Valve type: angled shut-off and flow control valve for hydronic systems
 Application: designed for water-based heating circuits and radiators
 Installation position: suitable for supply or return line mounting
 Form factor: compact angled body for space-constrained installations
How to use
Shut off the system and relieve pressure in the circuit before installation. Fit the valve to the 1/2" pipe connection thread on the radiator or pipework and tighten to the recommended torque using appropriate tools and sealing method for the system. After mounting, check alignment and ensure the valve spindle operates smoothly to open and close the flow. Use the valve to regulate flow by adjusting the spindle position or to isolate a radiator by closing the valve during maintenance. After any work, re-pressurize the system and check for leaks around connections.
Usage recommendations
Install and service the valve according to local regulations and heating system guidelines. Use compatible sealing materials for the threaded connections and avoid excessive torque to prevent damage. Where required, combine the valve with compatible thermostatic or manual actuators following the actuator manufacturer's instructions.
