WEH | More efficient CO2 filling for residual and non-residual pressure valves

WEH® TW52

with external threads within seconds – without hand tightening. The TW52 has

been developed especially for filling of gaseous and liquid CO2, as well as for

refrigerants. Simply pull back the grip sleeve of theTW52 and place the connector

onto the external thread of the cylinder valve. The WEH® clamping jaws

grip onto the cylinder valve thread and provide a pressure-tight connection.

Then open the cylinder valve to release the pressure. The filling process starts.

The TW52 connector is also suitable for filling one litre cylinders, e.g. for soda

drinks. Rated for a pressure range of max. 250 bar, the connector is available

for external thread connections in accordance with the corresponding national

standard e.g. DIN, CGA, BS, NF, etc.

When combined with the WEH® TVCO2 linear valve, the TW52 connector is

especially environmentally friendly. The TVCO2 linear valve enables the recirculation

and controlled discharge of the residual gas and starts or stops the

filling procedure. Simply connect the TVCO2 linear valve to the TW52 quick

connector. When disconnecting after filling the TW52 vents automatically.

The vented gas can be recirculated via a vent pipe and vented remotely, with

minimum environmental impact. When using the TW52 with linear valve, the

connector can be used up to a max. pressure of 150 bar.

In addition to this connector WEH offers a wide range of quick connectors

for the gas industry. For almost any valve configuration - internal or external

threads, with or without residual pressure valve, Pin-Index connection – WEH

has just the right connector. All quick connectors conform to the Pressure

Equipment Directive (PED) and are subjected to extensive pressure and

durability tests.
