Thermostatic Angle Valve Herz 1/2" special body, model 1772891

Thermostatic Angle Valve Herz 1/2" special body, model 1772891 is a compact radiator valve designed for controlling flow in hot water heating systems. The valve has a special angled body that simplifies connection to radiators or heating circuits where space or piping orientation requires an offset solution. When combined with a compatible thermostatic head or actuator, this valve enables automatic temperature regulation and hydraulic balancing in residential and commercial room heating installations.

Advantages

The valve offers stable thermostatic control when used with a matched actuator, allowing precise room temperature maintenance and reduced energy waste. Its angled special body provides flexibility for installations in confined spaces and improves alignment with radiator inlet piping. Manufactured by Herz, the valve is suitable for standard 1/2" connections and supports reliable long-term operation in typical hydronic heating systems.

Suitable for

• Domestic radiator connections in apartments and houses
• Commercial radiator installations in offices or public buildings
• Retrofitting existing heating circuits where angled connection is required
• Systems requiring thermostatic control and hydraulic balancing

Key specifications

• Connection size: 1/2" suitable for common radiator fittings
• Valve type: thermostatic angle valve with special angled body
• Material and construction: corrosion-resistant materials suitable for hot water heating systems
• Compatibility: designed to work with compatible thermostatic heads or actuators for automatic temperature control
• Application: intended for hot water (hydronic) radiator heating circuits

How to use

Install the valve inline with the radiator inlet pipe following standard plumbing practice and local regulations. Ensure correct orientation of the angled body to match the piping layout, and tighten connections to recommended torque values. Mount a compatible thermostatic head or actuator on the valve following the head manufacturer's instructions. After installation, bleed the radiator and test the system for leaks, then set the thermostatic head to the desired room temperature for automatic regulation.

Usage recommendations

Use the valve with thermostatic heads specified for radiator control to ensure accurate temperature regulation. During installation choose fittings and sealing materials appropriate for hot water systems and perform commissioning to verify hydraulic balance. Regularly inspect for leaks and ensure the actuator/head is free from obstructions to maintain efficient operation.
