Product information

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. Materials and design focus on serviceability and routine maintenance needs.

Suitable for

  • Domestic gas supply shutoff for stoves, boilers and meters
  • Small commercial heating systems and gas appliances
  • Maintenance and repair work where a manual isolation valve is required
  • Installation in confined or retrofit piping layouts with DN‑20 connections

Key specifications

  • Connection size: DN‑20 (nominal diameter 20 mm)
  • Type of control: manual lever on/off operation
  • Application: gas supply lines and heating systems for residential and light commercial use
  • Function: shutoff/isolation valve for gas flow control
  • Design: compact body suitable for installation in limited spaces

How to use

Install the valve in-line with DN‑20 gas piping following applicable local gas installation codes and safety practices. Ensure connections are tightened and sealed according to the pipe fitting method in use. Operate the manual lever to the open position for normal gas flow and to the closed position to isolate the downstream section. Before performing maintenance downstream, verify that gas is securely shut off and that the area is ventilated and checked for leaks by a qualified person.

Usage recommendations

Use the valve only with gases for which it is rated and within the pressure and temperature limits specified by local regulations; have installation and leak testing carried out by a qualified technician. Periodically inspect the valve and surrounding piping for signs of wear or leakage and operate the lever occasionally to confirm free movement.
