The same Series 8320 valve body, wound instead for a 120 V DC control supply, makes the ASCO 8320B139 120 VDC suitable for plants that run their control circuits from DC.
Series 8320 is ASCO's 3-way, direct-acting solenoid valve family for small flows. A 3-way valve pressurises and exhausts one port, so it is widely used to pilot larger valves and to drive single-acting actuators and cylinders.
Downtime on a fluid line rarely comes from the pipe itself. It comes from a valve that sticks, leaks or burns out its coil at the wrong moment. Choosing a genuine ASCO valve with the correct voltage, port size and function first time avoids repeat call-outs, mismatched spares and the cost of a second shutdown. It also keeps your spares list simple, because the same ASCO series can often cover several points across the plant.
Being direct acting, the valve does not depend on a minimum line pressure to shift. That makes the ASCO 8320B139 120 VDC a dependable choice for instrument air, pilot circuits and actuator control on process skids and machinery.
Need a different rating within the family? Compare the ASCO 8320B139 120/60 VAC (120 V AC / 60 Hz) or the ASCO EFHT8320G146 DC (DC, see nameplate for exact voltage, 1/8" ports, 3-way), and keep the same installation approach.

Who This Product Is Best For
-
Pilot control of larger process valves
-
Single-acting actuators and spring-return cylinders
-
Instrument air circuits on skids and machinery
How to Specify & Install It
-
Check the ASCO 8320B139 120 VDC nameplate, including the part number and 120 V DC rating, against your line, media and control circuit.
-
Isolate and depressurise the line, then install the valve with the flow direction marked on the body, keeping thread sealant and debris out of the ports.
-
Wire the coil to the correct supply and earth it in line with the ASCO installation instructions.
-
Energise and de-energise a few times to confirm clean switching and no leakage before returning the system to service.
Frequently Asked Questions
What is the ASCO 8320B139 120 VDC used for?
It is a 3-way valve used to pilot larger valves or to pressurise and exhaust single-acting actuators and cylinders.
Does the 8320B139 120 VDC need line pressure to operate?
No. Series 8320 is direct acting, so it switches without needing a minimum pressure differential.
What voltage is the 8320B139 120 VDC coil?
It is rated for 120 V DC. Match this exactly to your control supply, because a wrong voltage can burn out the coil or stop the valve shifting.
Should I choose the 8320B139 120 VDC or another ASCO model?
Start with your supply voltage, port size and required function. The 8320B139 120 VDC is 120 V DC. If you need 120 V AC / 60 Hz, the ASCO 8320B139 120/60 VAC may suit better. If you need DC, 1/8" ports and 3-way operation, the ASCO EFHT8320G146 DC may suit better. Contact our team to confirm.
How should I maintain the 8320B139 120 VDC?
Keep the media clean with upstream filtration, check periodically for leakage and coil overheating, and use the correct ASCO rebuild kit or coil when service is needed.
What is the most common mistake when ordering a solenoid valve?
Ordering the right series with the wrong coil voltage or port size. Always confirm the full part number from the nameplate.
Is genuine ASCO stock available with UAE shipping?
Yes. Genuine ASCO stock ships free across the UAE. Contact General Tech Services LLC for current pricing and lead time.
