Adafruit 12V Plastic Water Solenoid Valve 1/2" NPS 0.02-0.8 MPa

SKU CH-KYTF-6G4M8

Controls water flow in robotic gardening projects with 12 VDC actuation down to 6 VDC and 0.02–0.8 MPa pressure range

  • TypeSensors
  • Opens with just 12 VDC applied
  • Actuates down to 6 VDC for flexible control
  • Handles 0.02–0.8 MPa working pressure range
  • Responds in ≤0.15 s open and ≤0.3 s close
  • Single-direction flow with 1/2" NPS outlets

12V Plastic Water Solenoid Valve

This 12V plastic water solenoid valve controls liquid flow in robotic gardening and automation projects. It features two 1/2" Nominal non-taped National Pipe outlets and operates with single-direction flow. The valve remains closed until voltage is applied to the terminals. It is designed for builders who need electronic fluid control in low-pressure systems.

Sustained pressure performance

The valve requires a minimum pressure of 0.02 Mpa (3 PSI) to operate due to its internal gasket arrangement. It functions within a working pressure range of 0.02 Mpa to 0.8 Mpa and a temperature range of 1 to 75 degrees. Response times are 0.15 seconds to open and 0.3 seconds to close under standard 12VDC actuation. It is not suited for zero-pressure or gravity-fed systems that cannot meet the minimum pressure threshold.

1/2" NPS interface limits

The 1/2" Nominal Pipe Size outlets accept standard NPS fittings without tapered threads. The valve actuates at the rated 12VDC but can operate down to 6VDC with slower opening speed. Driving the coil requires a TIP120 or N-Channel power FET with a 1N4001 kickback diode for microcontroller compatibility. Reverse flow is prevented by the single-direction design, limiting installation orientation.

Questions about this item

How much heat or noise does the 12V solenoid produce when energised continuously?

The valve operates silently with no moving parts except the plunger; power draw at 12V is low, so heat rise is minimal during all-day use.

What driver circuit and power supply must I already have to switch this valve from a microcontroller?

Use a TIP120 or N-channel power FET with a 1N4001 kickback diode, fed from a 9V or 12V 1A DC adapter.

Will the 1/2" NPS threads on this valve mate directly with the 1/2" NPT fittings on my existing plumbing?

The outlets are 1/2" nominal NPS (non-tapered); they seal with a gasket and require a minimum 0.02 MPa (3 PSI) line pressure to open.
