## Summary description

Straight thermostatic radiator valve Varioterm, connection GW1/2 x GZ1/2 with presetting. Designed to regulate flow and temperature in heating systems, the valve provides manual preset adjustment to limit maximum flow and ensure stable radiator performance. Suitable for domestic and commercial radiators where compact straight connection and flow control are required.

## Long description

The Varioterm thermostatic valve straight GW1/2 x GZ1/2 with presetting is a compact control fitting for radiator heating systems. Designed to regulate flow and temperature, the valve enables manual preset adjustment to limit the maximum flow through the radiator. The straight connection GW1/2 x GZ1/2 provides a direct inline installation that fits common domestic and light-commercial radiator pipework, delivering stable performance and simple integration into existing systems.
Advantages
This straight Varioterm valve offers precise flow control through an adjustable preset mechanism that restricts maximum flow and helps balance radiators across the system. Its compact straight body simplifies installation where inline connections are required, and the construction is suitable for standard radiator fittings, ensuring compatibility with typical GW1/2 x GZ1/2 pipe terminations. The valve design promotes stable radiator temperatures and contributes to even heat distribution when used as part of a properly commissioned heating circuit.
Suitable for
Domestic radiator installations with GW1/2 x GZ1/2 connections
Light commercial radiator systems requiring compact straight valves
Hydronic systems where flow balancing and preset limiting are needed
Replacement of existing straight radiator valves with the same connection standard
Key specifications
Connection type: straight GW1/2 x GZ1/2
Function: thermostatic radiator valve with manual presetting for flow limitation
Application: radiator flow and temperature regulation in heating systems
Installation orientation: inline/straight
Suitable for: domestic and light-commercial radiator systems
How to use
Install the valve inline with the radiator inlet or outlet using compatible GW1/2 x GZ1/2 fittings, ensuring system water is isolated and drained as required before work. Set the presetting to limit the maximum flow during initial balancing: rotate the preset control to the desired stop position and lock it if applicable. After installation, restore system pressure, purge air from the radiator and test operation with the thermostatic head or actuator fitted according to the manufacturer of the control head. Periodically check the preset position and valve operation during routine system commissioning or maintenance.
Usage recommendations
Use together with a compatible thermostatic head or actuator designed for radiator valves. For effective system balancing, perform flow balancing during commissioning and verify individual radiator temperatures. When replacing an existing valve, confirm thread type and orientation to avoid incompatible fittings.
