Series 2184

The Goetze Series 2184 safety shut-off valve with a gunmetal body is designed to shut off filling lines on cryogenic tanks and cryogenic systems. It shuts off the filling line as soon as the tank pressure exceeds the limit set on the pilot valve.

The pilot valve and the straightway form shut-off valve are mechanically coupled. The pilot valve monitors the vessel pressure and triggers the closure of the shut-off valve. Pressure monitoring and the closing operation take place without any external power supply. The closing time is less than 30 ms.

The Goetze 2184 is available in DN 25 with flange connections and in DN 40 with flange connections or Soldering sockets. The shut-off valve body is made of CC499K gunmetal. The temperature range extends from −320,8 °F to +149 °F (−196 °C to +65 °C); separate operating limits apply for oxygen.

Typical application media include cryogenically liquefied nitrogen (LIN), oxygen (LOX), carbon dioxide (LCO₂) and argon (LAr). Due to its red brass body, this series is not suitable for acetylene. The valve is factory-set, sealed and manufactured oil- and greasefree.
