VARTCO radiator valve 1111250010 — thermostatic valve for heating systems

VARTCO radiator valve 1111250010 is a thermostatic valve intended for use in hot-water central heating systems. Designed to control flow to radiators, it enables room temperature regulation and hydraulic balancing between heating circuits. The valve is suitable for installation during new fitting or replacement of existing radiator connections and accepts manual or thermostatic actuator heads depending on the chosen fitting method.

Advantages

The valve provides accurate flow regulation for individual radiators, which helps maintain consistent room temperatures and improves overall system balance. Its construction supports straightforward installation and service access, reducing maintenance time. Compatibility with both manual and thermostatic heads allows flexible control strategies, from simple on/off adjustment to automatic temperature-based regulation. The compact design fits standard radiator connections and is suitable for residential and light-commercial applications.

Suitable for

• Replacement of existing radiator valves in hot-water central heating
• New radiator installations in residential buildings
• Hydraulic balancing and flow control in multi-radiator systems
• Integration with manual or thermostatic actuator heads

Key specifications

• Type: thermostatic radiator valve for hot-water heating
• Function: flow control and temperature regulation at the radiator
• Connection: standard radiator connection compatible with common fittings
• Control options: manual or thermostatic actuator head compatibility
• Application: residential and light-commercial central heating systems

How to use

Install the valve on the radiator inlet according to the system piping and the valve's orientation markings. Ensure the heating circuit is isolated and drained as needed before replacement or installation. Fit the appropriate actuator head: a manual knob for direct adjustment or a thermostatic head for automatic temperature control. After installation, open the system, purge air from the radiator, and check for leaks. Adjust the valve or thermostat head to achieve desired room temperature and perform hydraulic balancing across the system as required.

Usage recommendations

Use the thermostatic head in living spaces to maintain stable temperatures and energy-efficient operation. Periodically check the valve and actuator for free movement, and bleed radiators after initial installation or maintenance. When replacing older valves, verify compatibility with radiator connection sizes and piping to ensure proper sealing and function.
