Thermostatic Radiator Valve Herz 3/4" Straight with Continuous Adjustment (1762369)

Herz thermostatic radiator valve 3/4" straight with continuous adjustment is a straight-line valve designed for control of hot-water radiators and convectors. The valve enables stepless regulation of flow to maintain a preset room temperature when combined with a compatible thermostatic head or used manually. Constructed for reliable performance in residential and commercial heating systems, the valve supports precise balancing of heating zones and contributes to efficient energy management.

Advantages

The straight design provides a compact connection for radiator inlets, while continuous (stepless) adjustment allows fine flow control and accurate temperature regulation. The valve is compatible with manual and thermostatic actuators, offering flexibility for different installation scenarios. Durable construction and standard thread connection ensure straightforward installation and long-term operation in typical central heating systems.

Suitable for

• Hot-water radiators in residential apartments and houses
• Convectors and towel warmers where a straight valve configuration is required
• Zoned heating systems requiring precise flow balancing
• Installations that use manual knobs or thermostatic heads for temperature control

Key specifications

• Connection type: straight radiator valve with 3/4" thread
• Adjustment: continuous (stepless) flow control
• Intended medium: hot water for central heating
• Compatibility: designed for use with manual knobs or thermostatic heads
• Typical applications: radiators, convectors, towel rails in heating circuits

How to use

Install the valve in the radiator inlet line following standard plumbing practice and local regulations. Mount a compatible thermostatic head or manual knob on the valve spindle depending on whether automated temperature control or manual operation is required. Adjust the valve setting to regulate flow and achieve the desired room temperature; continuous adjustment allows gradual changes and fine tuning. Perform a system flush and pressure test before commissioning to prevent debris from affecting valve operation.

Usage recommendations

For reliable performance, pair the valve with a thermostatic head appropriate for the room size and heating load. During installation, ensure thread sealing and correct orientation according to the radiator manufacturer's instructions. Periodic checks and system water quality control will help maintain accurate regulation and long service life.
