## Summary description

Instal-Projekt Z8 radiator valve set with a right-sided shut-off tee (DWZ) designed for use with PEX piping. The set includes connection fittings in a chrome finish, suitable for controlling flow to radiators and isolating them for maintenance. Intended for central heating systems where PEX is used; provides on/off shut-off and standard radiator connection functionality.

## Long description

Instal-Projekt Z8 radiator valve set with a right-sided shut-off tee (DWZ) is designed for use with PEX (polyethylene) piping in central heating systems. The set provides a chrome-finished connection and valve assembly that enables flow control to a radiator and allows isolation of the appliance for service or replacement without draining the entire system. The product combines a compact valve body and a threaded shut-off tee configured for right-handed installation.
Advantages
The chrome finish offers corrosion resistance and a smooth surface that is easy to clean during installation and maintenance. The right-sided shut-off tee (DWZ) enables convenient shut-off and balancing of individual radiators. Components are sized and shaped for a standard radiator connection, facilitating compatibility with common PEX installation practice and reducing installation time when replacing or servicing existing valves.
Suitable for
Domestic and commercial central heating systems using PEX piping
Replacement of existing radiator valves with right-sided shut-off configuration
Situations requiring isolation of a single radiator for maintenance or repair
New radiator installations where compact chrome fittings are desired
Key specifications
Valve type: right-sided shut-off tee for radiator connection
Material/finish: chrome-plated connection fittings and valve body surface
Piping compatibility: designed for PEX (polyethylene) pipes
Function: on/off shut-off and flow control to radiator
Installation orientation: right-hand configuration
How to use
Shut off the central heating system and drain the section of pipework if required before replacing or installing the valve set. Fit the shut-off tee to the radiator inlet using the appropriate PEX connection method and ensure all fittings are tightened to the manufacturer’s recommended torque. Once installed, open the system valves and check for leaks at all joints. Use the valve to isolate the radiator for maintenance and operate the control to regulate flow or completely shut off the radiator when needed.
Usage recommendations
Use with compatible PEX tubing and appropriate compression or crimp fittings recommended for the pipe system. Verify installation by pressure testing the circuit and follow local regulations and heating system guidelines when performing service or replacement.
