## Long description

Instal‑Projekt Z15 PEX right C31 D50 thermostatic radiator valve set is a compact control kit designed to regulate radiator flow and maintain stable room temperature. This set is manufactured for right‑hand PEX connections and is compatible with modern heating systems where balanced distribution and easy temperature control are required. The C31 finish provides a neutral, corrosion‑resistant surface suitable for visible installations, while the D50 valve dimension indicates the valve body size and connection proportions for direct mounting on compatible radiators.
Advantages
The valve set provides precise thermostatic control to keep room temperature steady without constant manual adjustment. Its design for PEX piping ensures reliable sealing and reduced risk of leaks when installed with appropriate fittings. The right‑hand orientation simplifies installation in applications where piping layout or radiator inlet position requires a right‑side connection. The compact D50 valve body enables installation in tight spaces while maintaining adequate flow range for typical residential and light commercial radiators.
Suitable for
 Residential radiator installations with right‑hand PEX supply lines
 Light commercial heating systems requiring thermostatic control and balancing
 Retrofit projects where a compact valve with a neutral finish is needed
 Systems using PEX piping and compatible radiator adapters
Key specifications
 Connection type: right‑hand PEX connection for radiator inlet
 Valve dimension: D50 valve body size suitable for compact radiator fittings
 Finish: C31 corrosion‑resistant surface suitable for visible mounting
 Function: thermostatic flow regulation for temperature control and radiator balancing
 Compatibility: designed for use with PEX piping and standard radiator adapters
How to use
Install the thermostatic valve set on the radiator inlet following the radiator and piping manufacturer instructions. Ensure the right‑hand orientation matches the supply line layout. Connect PEX tubing using approved compression or crimp fittings and verify sealing before pressurizing the system. After installation, set the thermostat head to the desired room temperature range and bleed the radiator to remove trapped air. Check for leaks and confirm correct flow by balancing adjacent radiators if necessary.
Usage recommendations
Use compatible PEX fittings and follow local plumbing codes during installation. Periodically check the valve and thermostat head for free movement, and perform system balancing after installation or when changes to piping or radiators are made. For best performance, avoid installing the thermostatic sensor directly behind furniture or curtains that may interfere with accurate room temperature sensing.
