PARKER 991-000209-008 (V2 series miniature solenoid valve, original from the United States)

Series: 991=V2 series (15mm wide, direct acting, 3/2-way)

Origin: United States (Parker Precision Fluidics factory)

Model analysis:

991: V2 Micro Pneumatic Valve Series

0002: 3/2-way, normally closed (NC), low pressure type (vacuum~15psi/1.0bar)

09：DC12V（±10%）

008: Standard configuration, PTFE seal, inverted hook interface

1、 Core parameters

Structure: 3/2 direct acting, spring reset, normally closed (NC)

Voltage: DC12V (power consumption ≈ 1.0W)

Pressure: Vacuum~1.0bar (15psi) (low pressure/vacuum specific)

Interface: 4mm (5/32 ") hook, compatible with flexible trachea

Flow rate: ≈ 20 SLPM (Δ P=5bar)

Sealing: PTFE (Teflon), corrosion-resistant, low temperature resistant, suitable for clean gases

Valve body: PBT engineering plastic, lightweight (about 34g)

Response: ≤ 30ms; lifespan: ≥ 25 million cycles

Medium: Clean, dry, oil-free air/inert gas (oxygen, nitrogen, etc.)

Environment: 0-70 ℃, moisture-proof and dustproof

2、 Key characteristics

Low pressure/vacuum adaptation: Stable vacuum start-up, low working pressure ≈ 0.2 bar, suitable for negative pressure control.

PTFE seal: resistant to chemical corrosion, low leakage (<0.2 sccm), suitable for medical/analytical instruments.

Low power DC12V: 1.0W power consumption, supports battery power supply, suitable for portable devices.

Compact and lightweight: 15mm wide x 44mm long x 17mm high, weighing only 34g, easy to integrate.

Original American craftsmanship: precision assembly, helium inspection grade sealing, better lifespan and stability than domestic alternatives.

3、 Key points for installation and use

Flow direction: The arrow on the valve body must be consistent with the airflow, as reverse installation may cause internal leakage.

Interface: The 4mm hook is securely plugged in. It is recommended to add clamps after piping to prevent detachment.

Air source: Equipped with a 5 μ m filter at the front end, the medium is free of water, oil, and dust (protected by PTFE sealing).

Electrical: DC12V (10.8-13.2V), regardless of polarity; Avoid 100% long-term power on (recommended ≤ 80% ED).

Attitude: The coil is best placed vertically upwards and can be installed at any angle to avoid long-term inversion.

4、 Typical applications

Medical equipment: ventilators, oxygen concentrators, nebulizers, monitors, gas path switching

Analytical instruments: gas analyzer, chromatograph, vacuum system control

Portable devices: portable pneumatic devices, battery powered instruments

Industrial low-pressure pneumatic: small pneumatic actuators, vacuum adsorption control
