The TK23 CNG defueling nozzle is designed specifically for evacuating and discharging CNGof cylinder bundles (e.g. on trailers).
The TK23 CNG is equipped with a pin, which opens the check valve in the TN5 CNG receptacle (without filter) and releases the flow. Now the CNG can be discharged from the cylinder bundles. Connecting and disconnecting can only occur in depressurised condition. The TK23 CNG is not equipped with an integrated check valve.
The WEH® TK23 CNG defueling nozzle is suitable for WEH® TN5 CNG receptacles without filter.
