Service sensor element RA/V for radiator valve, inner diameter 34 mm, Danfoss customer return (EC/691262323)

Service sensor element RA/V for radiator valve, inner diameter 34 mm, is a replacement sensing and actuating component designed to fit Danfoss-type thermostatic radiator valves. It provides temperature-responsive movement inside the valve assembly to open or close flow passages according to the sensed temperature. The element is intended for use in maintenance and repair of heating systems where a matching RA/V sensor capsule is required to restore correct valve operation.

Advantages

This service sensor element offers precise temperature-responsive actuation compatible with Danfoss-style radiator valves, enabling reliable control of radiator flow. The standardized inner diameter of 34 mm ensures straightforward fitting into compatible valve housings. As a direct-replacement component, it supports timely maintenance and reduces the need for full valve replacement when the original sensor element is faulty.

Suitable for

• Replacement of a faulty RA/V sensing capsule in Danfoss-compatible thermostatic radiator valves
• Routine maintenance and repair of hydronic heating systems
• Restoring temperature-responsive valve operation in residential or commercial radiators

Key specifications

• Type: Service sensor element for radiator valve (RA/V)
• Inner diameter: 34 mm
• Function: Temperature sensing and mechanical actuation within thermostatic valve assembly
• Compatibility: Designed for use with Danfoss-style radiator thermostatic valve housings
• Application environment: Hydronic heating systems, radiators

How to use

Switch off the heating system and isolate the radiator before beginning work. Drain the radiator or close the necessary valves to relieve pressure and prevent water loss. Remove the thermostatic valve head according to the valve manufacturer’s instructions, then extract the old sensor element from the valve housing. Insert the RA/V service sensor element with its 34 mm inner diameter into the valve body, ensuring correct seating and alignment. Reassemble the valve head, restore system pressure, and check for proper valve operation and absence of leaks. If uncertain, consult technical documentation or a qualified heating technician.

Usage recommendations

Use this RA/V sensor element for direct replacement of compatible Danfoss-type sensor capsules. Always verify mechanical fit and valve model compatibility before installation. Follow local safety standards and shut-off procedures when working on heating systems; consider professional service for complex repairs.
