This electronic timer drain valve is an automatic drain for air compressor tanks, filters and dryers. A solenoid coil opens a normally closed brass 1/2 inch (DN15) valve on a set timer cycle so condensed water is released without anyone standing at the tank. It is rated to a maximum working pressure of 1.0MPa and comes in 220V AC, 24V DC and 12V DC versions.
Features and benefits:
- Timer controlled draining: ON time is set in seconds (0.5, 2, 4, 6, 8, 10) and OFF time in minutes (0.5, 9, 18, 27, 36, 45), so you can match the purge to how much water your tank collects
- TEST button and ON/OFF indicator lights: trigger a drain by hand and see at a glance whether the valve is open or closed
- Brass body with 1/2 inch (DN15) threaded ports: fits standard tank and filter drain points
- Manual blue ball valve handle and a double safety emergency switch: lets you drain by hand if the timer or power fails
- Stainless steel filter mesh and a brass cap in the package: the mesh helps keep debris away from the valve seat
- Available as a one-body type or a split-body type: pick the wiring control type in the options
- Class H insulation and IP65 protection: suited to a workshop environment
Applications:
- Draining condensate from air compressor receiver tanks
- Clearing water from compressor line filters and dryers
- Workshop and garage compressed air systems
- Cooler and dry storage tank drain points
In the box:
- 1 x drain valve (pick voltage and wiring type in the options)
Note: Disconnect the supply and release tank pressure before fitting or servicing. Choose the voltage that matches your supply: 220V AC, 24V DC or 12V DC. Keep within the 1.0MPa maximum working pressure and the 2 to 55 ambient temperature range stated by the seller.

A: It opens on a timer to let condensed water out of the tank or filter, then closes again. This stops water building up in the receiver without you draining it by hand.. Q: How do I set how often the drain valve opens? A: Use the OFF time dial for the gap between drains (0.5 to 45 minutes) and the ON time dial for how long it stays open (0.5 to 10 seconds). The TEST button runs a drain on demand.. Q: What is the difference between the one-body and split-body types? A: The listing offers both as wiring control types, called One-body Type and Split-body Type. The seller gives no further detail on how they differ, so check your wiring needs before ordering.. Q: What size thread does this compressor drain valve have? A: The ports are 1/2 inch (DN15), threaded, in a brass body. Check your tank outlet thread before fitting.. Q: Can I drain it by hand if the timer stops working? A: Yes. There is a manual blue ball valve handle and a double safety emergency switch for draining without the timer..
