## Summary description

Straight thermostatic radiator valve Varioterm EFP without presetting, with thread M30x1.5 and connection sizes female 1/2” / male 1/2”. Designed to connect thermostatic heads and control flow in hot-water heating systems. Suitable for use on radiators where manual preset is not required. Provides compact mechanical control of flow with standard connection dimensions.

## Long description

Straight thermostatic radiator valve Varioterm EFP without presetting, with M30x1.5 thread and 1/2” female to 1/2” male connections. Manufactured for use in sealed hot-water heating systems, this Varioterm valve allows connection of a thermostatic head and provides mechanical flow control without factory presetting. Its straight design and standard thread make it compatible with common radiator fittings where manual preset is not required.
Advantages
The valve offers a compact and durable construction that fits standard M30x1.5 thermostatic heads and common 1/2” radiator connections. Absence of presetting simplifies installation for applications where balancing is performed elsewhere or not needed. The straight configuration reduces space requirements and aligns easily with axial radiator inlets, while the mechanical control element ensures reliable flow regulation over long service life.
Suitable for
Domestic and commercial hot-water radiators with M30x1.5 thermostatic heads
Installations where presetting of flow is not required or is handled by a separate balancing valve
Replacement of existing straight radiator valves with 1/2” connections
Systems requiring compact, axial valve orientation to save installation space
Key specifications
Connection type: straight valve with female 1/2” to male 1/2” fittings
Thermostatic head thread: M30x1.5
Mounting orientation: axial/straight
Control type: mechanical thermostatic valve without presetting
Application: hot-water central heating systems
How to use
Shut down the heating system and drain the radiator circuit before removing the old valve. Fit the Varioterm EFP valve to the radiator inlet using the 1/2” connections, ensuring sealing with appropriate PTFE tape or joint compound where required. Securely attach the thermostatic head to the M30x1.5 thread. After installation, refill and vent the system, check for leaks and confirm that the thermostatic head responds to temperature changes and modulates flow as expected.
Usage recommendations
Use the valve in systems with compatible thermostatic heads and standard 1/2” radiator fittings. If hydraulic balancing is needed, perform balancing with a dedicated presetting valve or balancing device elsewhere in the circuit. Inspect joints after first heat-up and periodically during service intervals to ensure leak-free connections.
