Descriptions of 2/2 Way Normally Closed NBR Diaphragm Unid Type UW-15 Brass Solenoid Valve: Solenoid valve adopts electrical signals,it can be automatic or remote control to work. Automation components of medium pipeline, which has start and stop rapidly, stable performance, convenient to use. Can be installed at any angle, but it is a good choice when the horizontal tube keep upward. Used to control automatically the liquid and gas in the pipeline.
Characteristics: 1. The semi-direct type diaphragm structure without pressure to open, to extend the using field. 2. Using the plate diaphragm structure opening and closing with reliable. Then extent the product life. 3. Can choose plastic type, explosion-proof energy-saving, timing.

Brief intorduction of DC12V NBR Diaphragm Brass Solenoid Valve:
This liquid solenoid valve would make a great addition to your robotic gardening, aquarium, or pool project. There are two 1/2" outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can flow. Unlike the Plastic Solenoid Valve, this one does not have a gasket, so there is no minimum pressure requirement.
We tried this solenoid at various DC voltages and found we could actuate it down at 6VDC (although it was a little slower to open). We suggest a TIP120 or N-Channel power FET with a 1N4001 kickback diode to drive this from a microcontroller pin. For a power supply, 12V 5A power adapter will do the job.
If you want smaller, more basic valve, we also carry a plastic version which does have a minimum pressure requirement but has much lower power requirements.
These solenoid valves are not rated for food safety by any official standards. However, they are made of cast brass, with a rubber gasket made of NBR (Nitrile Rubber) so it can be used with any fluid that will not damage or be damaged by the rubber gasket material.
