説明

Compressed air is a promise. Every valve is the place where the promise is either kept or broken.

The Flow Keeper is a 2V025-08 direct-acting solenoid valve, a 2-position, 2-port, normally closed switch for air lines that answers in 0.05 seconds or less. Built to the widely used Airtac interchange pattern, it accepts DC12V, DC24V, or 220V coils and controls flow across a pressure range of 0 to 1.0MPa, with a proof pressure of 1.5MPa and a 2.5mm orifice.

Selection is simple: pick your coil voltage, then choose whether to run bare or with a 4mm to 12mm hose fitting already mounted. Bench builders, automation engineers, and pneumatic tinkerers will recognize the form factor instantly, because this is the valve design found inside half the automation rigs on the market.

This is not a fitting. It is a decision point your machines depend on.

Pneumatic systems are only as honest as their valves. A valve that sticks, leaks, or hesitates makes every downstream cylinder a liar. The Flow Keeper is built for the engineer who has rebuilt the same circuit one too many times and wants the valve to simply do its job. The direct-acting design means the armature moves the seal directly through the orifice, so it opens and closes in fifty milliseconds with no pilot air to bleed. The Airtac-type footprint and multiple coil voltages mean it drops into existing brackets and wiring, and the option of pre-mounted hose fittings removes one more trip to the fitting drawer.

Built For

Automation benches where a reliable air switch is the heartbeat, pneumatic cylinders that need a clean fast release, air gun stations, packaging lines, and lab rigs, anywhere a normally-closed valve must open on command and seal when power drops Maintenance crews standardize on this form factor because the 2V025-08 pattern is stocked by automation suppliers worldwide, making a service replacement a routine event..

Questions & Answers

Q: Which voltage should I pick?

A: Match the coil voltage to your control system: DC12V or DC24V for PLC and relay logic, 220V for direct mains switching.

Q: Is it normally open or normally closed?

A: It is normally closed, meaning the port seals with no power and opens the instant the coil energizes.

Q: What pressure can it handle?

A: Working range is 0 to 1.0MPa, with a proof pressure of 1.5MPa for safety margin.

Q: Does it come with fittings?

A: You can order it bare or with a pre-mounted hose fitting from 4mm to 12mm, whichever matches your tubing.

Q: Is it compatible with Airtac systems?

A: Yes, it follows the widely used Airtac-type 2V025-08 form factor, so it slots into existing brackets and plumbing.

Q: What does direct-acting mean?

A: The coil directly moves the valve seal, so there is no pilot air requirement and response is immediate, making setup simpler in compact circuits.

Q: Can I use it with non-air fluids?

A: It is specified for air; for other media, check compatibility with the manufacturer or choose the appropriate valve type.

Q: Which fitting size should I order?

A: Match the hose inner diameter you are running, 4 to 12mm options are available, or order without fittings and plumb with your own adapters.

Q: What does a 2-position 2-port valve do in a circuit?

A: It switches one air path on or off, either blocking flow in the resting state (normally closed) or passing it, depending on the build.

Q: Is the coil replaceable?

A: The coil is the standard 2V025-08 pattern, so a replacement coil can be sourced and swapped if a coil ever fails.

Q: Can it be mounted in any orientation?

A: The valve operates in any mounting orientation, though keeping the coil uppermost is conventional for long service life.

Q: What is the flow rate like?

A: With a 2.5mm orifice and direct-acting design, it suits pilot circuits, small cylinders, and air guns rather than high-volume main lines.

Reliable switching for my small cylinder rig

Normally closed behavior is correct, opens instantly on power and seals tight when dropped. Built a small pick-and-place demo around it and it has run flawlessly.

Good valve with the 6mm fitting option

Ordered with the 6mm hose fitting mounted and it saved me a trip to the fitting drawer. Works perfectly on my bench air gun setup. Pressure holds with no leaks.

Exactly the Airtac replacement I needed

Dropped into an existing pneumatic circuit where the old valve died. DC24V coil, clean switching, and the 0.05s response is real. The 2V025-08 footprint is identical.
