## Long description

The Varioterm Two-pipe straight connection valve Type V GZ3/4 x GW3/4 is a mechanical connection valve for hydronic heating and cooling systems. It features a straight design with male GZ3/4 and female GW3/4 threaded ends to join supply and return lines to radiators or modules. The valve provides a compact junction point for water-based systems and is intended for direct inline installation in two-pipe circuits.
Advantages
This two-pipe straight connection valve offers a robust metal construction and standardized G3/4 threads for compatibility with common plumbing fittings. Its straight-through configuration minimises pressure drop and simplifies piping layout. The mechanical design requires no external power and provides a reliable physical junction that supports routine maintenance and straightforward replacement if needed.
Suitable for
Connecting radiators to supply and return lines in two-pipe heating systems
Integrating fan-coil units or heating/cooling modules into closed hydronic circuits
Replacement of existing straight connection points with standardized G3/4 threaded fittings
Key specifications
Connection type: straight inline valve between two pipes
Thread configuration: male G3/4 to female G3/4
Application: water-based heating and cooling (hydronic) systems
Installation orientation: straight (inline) installation
Material: metal construction suited for plumbing connections
How to use
Prepare compatible G3/4 threaded supply and return pipes and ensure the system is depressurised and drained before installation. Thread the male G3/4 end into the corresponding female connection on the pipe or device, and attach the female G3/4 end to the mating male fitting. Use appropriate sealing tape or joint compound on threads if required by local practice. After installation, refill and pressurise the system, then check for leaks and proper flow through the connected radiator or module.
Usage recommendations
Inspect thread condition and clean mating surfaces before assembly. Tighten connections to manufacturer-recommended torque levels where available, and test the system at working pressure to confirm leak-free performance. Use this valve in systems with compatible water quality and follow local codes for installation and maintenance.
