Description
GESTRA AK 45 Condensate Drain Valve | PN 40 DN 15–25
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.
At shut-down or when the pressure falls below the closing pressure the valve opens and accumulated condensate is automatically drained away.
Function
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.
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.

Applications of GESTRA AK 45 Condensate Drain Valve
The GESTRA AK 45 is widely used in:
- Steam pipelines and headers
- Heat exchangers
- Boilers and auxiliary systems
- Power plants
- Oil & gas facilities
- Chemical and petrochemical plants
- Industrial processing lines
Its precise flow control makes it ideal for safe condensate removal during start-up, maintenance, and operation.
Advantages of Using Original GESTRA AK 45
Choosing a genuine GESTRA AK 45 condensate drain valve ensures:
- High reliability and operational safety
- Reduced risk of water hammer
- Improved steam system efficiency
- Compliance with international quality standards
- Lower long-term maintenance costs
Using non-original or low-quality drain valves can lead to leakage, premature failure, and system damage.
GESTRA AK 45 vs Standard Drain Valves
Unlike generic drain valves, the GESTRA AK 45 is engineered specifically for steam and condensate applications, offering:
- Better sealing performance
- Higher resistance to temperature and pressure fluctuations
- Consistent operation under industrial conditions
This makes the AK 45 a preferred choice for engineers, maintenance teams, and procurement professionals.
