There is disclosed a condensate drain, comprising: a body defining a drain chamber having a liquid-gas inlet and a liquid outlet; and a porous membrane having a pore size of about 0.2 &#x3bc;m or less disposed within the body between the liquid-gas inlet and the liquid outlet; wherein in use, the porous membrane permits liquid to pass therethrough but restricts the passage of gas.

Condensate drain

There is provided a valve element for a condensate trap comprising an expansion chamber in the form of a metallic bellows having a variable axial length and having first and second ends sealed with first and second end caps respectively. A valve closure member is provided on the second end cap and is arranged to cooperate with a valve seat. A first guide member is coupled to the first end cap and axially extends into the bellows and a second guide member is coupled to the second end cap, axially extends into the bellows and cooperates with the first guide member. This allows relative axial movement between the first and second end caps but restricts relative radial movement between the first and second end caps. This helps to ensure that the valve closure member properly seats on the valve seal.
