Thermostatic radiator valve Herz TS 90 straight 3/4" model 1772392

Thermostatic radiator valve Herz TS 90 straight 3/4" model 1772392 is a straight-mounted control valve designed for use with thermostatic heads to regulate radiator flow and maintain room temperature. Intended for integration into central heating systems, this valve fits 3/4" pipe connections and provides proportional regulation of heating circuits in both residential and commercial installations. The straight body allows compact installation in line with radiator connections and standard fittings.

Advantages

The valve offers precise flow control compatible with most thermostatic heads, enabling accurate temperature regulation. Its straight configuration simplifies installation where inline connections are required, and the robust construction ensures long-term reliability under normal heating system conditions. The design supports proportional regulation, which helps maintain consistent comfort levels while allowing efficient system balancing.

Suitable for

• Domestic radiators in apartments and houses
• Commercial radiator installations in offices and small public buildings
• Central heating systems requiring proportional flow control
• Retrofit projects where 3/4" straight connections are present

Key specifications

• Connection type: straight 3/4" threaded connection
• Function: thermostatic valve body for use with thermostatic actuator/head
• Regulation: proportional flow control for radiator circuits
• Installation orientation: straight/inline mounting
• Typical applications: residential and light commercial radiator systems

How to use

Install the valve in line with the radiator inlet using compatible 3/4" fittings and ensure correct sealing at the joints. Attach a compatible thermostatic head to the valve spindle according to the head manufacturer's instructions. After installation, bleed the radiator and commission the heating system, checking for leaks and verifying that the thermostatic head correctly modulates flow to maintain the set room temperature.

Usage recommendations

Use with thermostatic heads specifically matched to the valve spindle type and ensure regular inspection during annual system maintenance. When replacing existing valves, verify pipe size and connection type to confirm compatibility with the straight 3/4" configuration.
