Quick coupling / straight / pneumatic / stainless steel
manual actuation, with shut-off valve, for gas bottles
30 bar (435.11 psi)
The WEH® filling connector type TW59 is specifically designed for the filling of gas cylinders with propane and butane and represents a major step in the technology of safe application, economy, ergonomics and flexibility.
Type TW59 provides an intrinsically safe connection. The seal between the quick connector and the gas cylinder valve is mechanically actuated and the sealing force is increased by the gas filling pressure. This means that there is no need for a compressed air safety reservoir, the air supply is used to withdraw the seal when connecting / disconnecting in order to achieve effortless operation.
If needed, a second pneumatic inlet is provided for pilot pressure. This can be used to indicate the operational condition of the connector - i.e. whether connected or disconnected - and could for example be used to automatically begin the loading and unloading of the gas cylinders from the filling station.
No additional valves required
The integrated shut-off valve prevents the leakage of gas when connecting and disconnecting. The gas flow is immediately interrupted when disengaging the pressurized connector.
The quick connector type TW59 meets the requirements of the technical regulations for gases (TRG).
