Valve insert Herz TS-90-V — spare part for thermostatic valve (model TS-90-V)

Herz TS-90-V valve insert is a spare part designed to restore proper operation of compatible thermostatic valves in warm-water heating systems. It replaces the internal sealing and regulating elements of the TS-90-V series valve body, enabling precise flow control for radiators and other heat emitters. The insert is intended for maintenance and repair tasks where a degraded or leaking valve cartridge is diagnosed, providing a practical way to avoid full valve replacement while maintaining temperature control performance.

Advantages

The valve insert offers reliable sealing and consistent regulation of flow through the valve seat, reducing the risk of leaks and improving temperature stability. Its design ensures straightforward installation into the matching valve body, minimising downtime during repair. Constructed to meet the functional requirements of Herz TS-90-V series valves, the insert helps restore original performance characteristics and supports long-term operation of heating circuits when fitted correctly.

Suitable for (tasks / use cases)

• Repairing a leaking or malfunctioning Herz TS-90-V thermostatic valve
• Routine maintenance of radiator control valves in warm-water heating systems
• Restoring accurate flow regulation without replacing the entire valve body
• Service interventions by heating technicians and maintenance teams

Key specifications

• Compatibility: designed for installation in Herz TS-90-V series thermostatic valve bodies
• Function: replacement regulating/sealing insert for flow control
• Application: warm-water radiator and heating circuit use
• Material characteristics: corrosion-resistant internal components suitable for heating media

How to use

Isolate the heating circuit and drain the section containing the affected valve before beginning work. Remove the thermostatic actuator or handle and extract the old valve insert according to the valve manufacturer's instructions. Insert the replacement Herz TS-90-V cartridge into the valve body, ensuring correct orientation and full seating against the valve seat, then reassemble the valve and reinstall the actuator. Repressurise and bleed the system, and verify correct operation and absence of leaks.

Usage recommendations

For reliable results, use this valve insert only with compatible Herz TS-90-V valve bodies and follow standard safety procedures: depressurise the circuit, wear protective equipment, and check for leaks after commissioning. If uncertain about compatibility or installation steps, consult a qualified heating technician or refer to Herz technical documentation.
