## Long description

The INVENA GZ-20-020 DN‑20 gas valve is a compact manual shutoff device engineered for on/off control of gas flow in residential and light commercial installations. Designed to fit standard DN‑20 piping, this valve provides a straightforward means to isolate sections of a gas supply line or heating system for maintenance, repair, or safety shutoff. Its manual control lever allows direct user operation without auxiliary power, and its construction is intended for repeated operation in typical domestic and small commercial environments.
Advantages
The valve offers reliable shutoff performance with a simple manual mechanism that is easy to operate and inspect. Its DN‑20 compatibility ensures straightforward integration with common gas piping systems. The compact form factor facilitates installation in confined spaces and makes it suitable for retrofits and new installations.

How to use
