ASCO E290B002 | Piston Valve | Pressure Operated | Series E290
The ASCO E290B002 is a genuine piston valve from ASCO's Series E290 range (Pressure operated), suited to process lines where a coil on the valve would be exposed to heat or water. It is also a practical choice for plants switching valves with an air pilot signal. Genuine stock at General Tech Services LLC, UAE, with free UAE-wide shipping.

Some lines are better switched by air than by a coil sitting in the heat, steam or washdown. The ASCO E290B002 is a pressure-operated Series E290 piston valve, opened and closed by a pilot pressure signal.
A pressure-operated piston valve is opened and closed by a pilot pressure signal acting on a piston, rather than by a solenoid coil mounted on the valve. The pilot is usually switched by a small solenoid valve placed in a cooler, cleaner or safer spot.
In pneumatic systems, small components decide whether a machine runs smoothly or keeps stopping. A worn or mismatched valve leaks air, slows cylinders and makes fault-finding harder for maintenance teams. Fitting a genuine ASCO part with the right function and connections keeps the circuit predictable, cuts compressed-air waste, which is one of the most expensive utilities in a plant, and makes future replacement a simple like-for-like swap.
That arrangement suits hot, wet or washdown lines and higher-flow duties where a coil on the valve body would be exposed. The ASCO E290B002 belongs to ASCO's Series E290 range; confirm media, pressure, temperature and connection details on the ASCO datasheet before ordering.

Who This Product Is Best For
-
Process lines where a coil on the valve would be exposed to heat or water
-
Plants switching valves with an air pilot signal
-
Maintenance teams replacing an existing ASCO E290 valve
How to Specify & Install It
-
Check the ASCO E290B002 part number and datasheet ratings against your media, pressure and temperature.
-
Isolate and depressurise the line, then install the valve with the flow direction as marked.
-
Connect the pilot supply to the actuator port through a suitable pilot solenoid valve.
-
Apply and remove pilot pressure several times to confirm clean opening, closing and sealing.
Frequently Asked Questions
What does pressure operated mean on the E290B002?
The valve is switched by a pilot pressure signal acting on its piston, not by a coil fitted to the valve.
What controls the pilot signal?
Usually a small solenoid valve that sends or vents pilot air to the actuator. Check the required pilot pressure on the datasheet.
How can I confirm the E290B002 is the right replacement?
Compare the part number on your existing unit, or send us the nameplate details and our team will help you confirm the match.
How should I maintain the E290B002?
Supply clean, dry, filtered air, check for audible leaks during routine rounds, and replace the valve or its seals when switching becomes sluggish.
What is the most common mistake when ordering a pneumatic valve?
Choosing the wrong function or port size. Check the circuit diagram and the full part number before ordering.
