## Summary description

Herz TS-90-V valve insert is a replacement component for compatible thermostatic valves. Intended to restore correct valve function, it fits Herz TS-90-V series valves and provides reliable flow control in heating systems. Use for maintenance or repair of radiators and warm-water circuits to ensure leak-free operation and accurate temperature regulation.

## Long description

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)

How to use
Isolate the heating circuit and drain the section containing the affected valve before beginning work.

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.
