Data Sheet 810456-02 Issue Date: 05/04
Condensate Drain Valve
AK 45
PN 40, DN 15, 20, 25 (½", ¾", 1")
Space required for opening valve 40 mm
H²

g k D
System Description The AK 45 automatically drains condensate from steam systems during start-up, until the pressure in the system has
reached the adjusted valve closing pressure.
H¹
At shut-down or when the pressure falls below the closing pressure the valve opens and accumulated condensate is
automatically drained away.
Function
L
When there is no pressure the drain valve is held in the open position by the integral spring. As soon as the service
pressure has reached the closing pressure to which the AK 45 has been adjusted, the valve closes (by the differential
pressure acting on the valve cone against the force of the spring). When the pressure drops below the closing pressure,
the AK 45 opens by spring force.
Space required for opening plug 30 mm
AK 45 with flanged ends
A hand purging knob is provided, so that the AK 45 can be opened by hand with the system under pressure to clear any
deposits from the valve seat area.
The AK 45 is adjusted at our works to close at a differential pressure of 0.8 bar (12 psig).
The AK 45 is provided with an integral strainer.
