12 volt solenoid valve

For applications where low voltage and safety is of the utmost importance, such as water fountains, vending machines, and coffee makers, an ideal solution is small 12-volt solenoid valves and small compact, low-power valve coils that draw under 500 milliamp, 12 volt brass, stainless steel, and plastic solenoid valves (12vdc DC direct current or 12vAC alternating current).

They have lower power consumption and energy-saving qualities, but they also have the additional advantage of lower heat, which extends working life. Working with hard water applications calls for extra care because calcium (limescale) buildup is reduced by low heat. Most of the time, wall-mounted transformers or 12-volt battery packs can power low-power 12-volt solenoid valves.

Types of 12 Volts Solenoid Valves

Direct Acting Solenoid Valve

These valve types operate with the most basic mechanism. A plunger in a direct-acting solenoid valve, for instance, shuts a small aperture without the aid of an external force. As a result, these solenoid valves have a quick response time. They can also function under various pressures, ranging from the lowest to the highest permitted values. An orifice in a direct-acting solenoid valve that is NO (normally open) or NC (normally closed) closes when an electric current is applied.

The orifice in an NC direct-acting valve is closed and only opens when the solenoid coil windings are energized. The three-way two-position solenoid valve is a different type of direct-acting valve. The only difference between it and the 2/2 valve is how fluid is exhausted. It can do this by utilizing a seal at the top or bottom of the plunger. There are benefits and drawbacks to using direct-acting solenoid valves.

First off, these valves are precise and quick to react. These valve types also benefit from operating with a range of line pressures, from low to high. The main drawbacks of direct-acting solenoid valves are their size and strength. Additionally, because the valves depending on the solenoid coil's closing force, they frequently require large currents. If the systems are large-scale, this frequently entails huge solenoid construction.

Pilot-Operated Solenoid Valve

A pilot solenoid valve, also known as an indirect-operated valve, uses the pressure differential between the valve ports to close or open the outlet. These valves include a few extra pieces and are more complicated than direct-acting valves.

Working Principle of a 12 Volt Solenoid Valve

A diaphragm separates the intake and outlet ports of these solenoid valves. The medium can move into the upper chamber through a tiny hole in the diaphragm. This chamber is linked to the low-pressure port via a short conduit. The valve is kept closed by the pressure in the system and a little spring. The pilot orifice opens when the solenoid is activated, lowering the pressure in the upper chamber.

The diaphragm lifts, as a result, allowing the medium to flow from the intake to the outlet port easily. The pressure chamber amplifies a pilot-operated solenoid valve's closing and opening forces. This makes it possible for tiny solenoids to control a high-flow line.

This solenoid valve typically doesn't require huge amounts of current because of the amplified pressures. However, pilot solenoid valves have a few restrictions despite their powerful action. First, they may control a medium that only moves in one direction because they are a one-way solenoid valve.

In addition to being slower than direct-acting solenoid valves, pilot solenoid valves require a minimum operating pressure level and cannot be used with 0-bar circuits. Pilot solenoid valves are appropriate for systems with sufficient pressure differential, such as irrigation systems and car wash equipment. The majority of their applications involve large flow rates or capacities. These consist of devices that regulate water flow, such as faucets.

Two Way 12 Volt Solenoid Valves

These valve types shut off or open the fluid flow using two ports. A two-way solenoid valve, for instance, is categorized as generally open if the orifice permits media to flow. At the same time, the coil is de-energized and normally closed when energizing the coil permits fluid to flow via either port. Solenoid valves that are generally closed, or NC, are more prevalent than those that are normally open. Systems with two-way solenoids that require media release and restriction. These consist of gear-like air compression devices.

Three-Way 12 Volt Solenoid Valve

Typically, a 3-way solenoid valve has three ports and two distinct orifices. Depending on the condition of the solenoid coil, the two orifices open in turn. These valve types typically have two inlet ports and one exit. Consequently, a three-way solenoid valve mainly combines two separate fluids when utilized in this form. Some three-way solenoid valves use a single inlet port and two exits. By routing a medium through the other outlet port, this type of design enables the valve to regulate the flow of a medium in one of the output ports. For instance, 3-way solenoid valves are used in domestic items like the dishwasher.

Four-Way 12 Volt Solenoid Valve

Four ports are used by this kind of valve: two pressure inlets and two exhaust outputs. To operate double-acting solenoid valve actuators, 4-way valves are frequently employed. This is because the actuator or cylinder receives incoming pressures through the input ports, and the exit pipes are large pressure holes.
