12V DC 1/2″ Electric Solenoid Water Air Valve Switch (Normally Closed)

12V DC Solenoid Water Air Valve Switch (Normally Closed) – 1/2″ controls the flow of fluid (liquid or air) and acts as a valve between high-pressure fluid! This liquid valve would make a great addition to your robotic gardening project. There are two ½” (Nominal NPT) outlets. Normally, the valve is closed. When a 12V DC supply is applied to the two terminals, the valve opens and water can push through.

The valve works with the solenoid coil which operates electronically with DC 12 volt supply. As it is a normally closed assembly, it opens the flow of fluids as soon as it is powered ON and stops/blocks the flow when the supply voltage removed.

Note:  While Connecting Valve in Flow pipeline, you need to mind the Input and Output direction of the valve. It will work only if you connect it in the right direction. (Hint: Inside the value, at one side you will find the filter this is the input side of the value)

Features:

1. Compact and convenient.
2. Easily installed and serviced
3. Precise and reliable.
4. The installation direction can be arbitrary Angle
5. Pressure-regulating valve (steady flow valve) function similar to the water flow switch
6. Not only can it provide a steady flow, but it also prevents the dry burning.
7. Suitable for fluids like water, oil, air.

Package Includes:

1 x 12V Solenoid Water Air Valve Switch (Normally Closed) – 1/2″

The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with built-in converter, easy to operate. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

A4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988.

There are no phase sequence tables, the high-frequency control interface programming etc. The application of A4988 interface is very suitable for a complex microprocessor is not available or overload. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increased step accuracy, and reduced power consumption.

Provide internal synchronous rectification contr

ol circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Don’t need special power-up sequencing. A4988 uses surface mount QFN package (ES), the size is 5 mm × 5 mm, nominal overall package height is 0.90 mm, with an exposed thermal pad to enhance the heat dissipation function.

Features :

1. Automatic current decay mode detection/choice.
2. Mixed with slow current decay mode.
3. The low power dissipation of synchronous rectifier.
4. Internal UVLO(ultra voltage lockout).
5. Crossover current protection.
6. Thermal shutdown circuit.
7. Ground fault protection.
8. Loading and short circuit protection.
9. The optional five-step mode: full, 1/2, 1/4, 1/8 and 1/16.
