Solenoid Valves - Electronic Pneumatic

A solenoid valve is an electro-mechanical device designed to control the flow of various process mediums such as steam, air, water, oil, and more. These valves can function independently or work together with other valves like ball valves, arranged on a manifold with several control operations.

Solenoid Valve Structure

The solenoid valve comprises two core components: the solenoid and the valve itself. The solenoid regulates the electromagnetic current, which in turn controls the opening and closing of the valve. Depending on the application, the valve seat might be soft or metallic. As current is applied, a magnet within the solenoid activates, allowing the valve to open.

The Core

The solenoid’s core, a magnetic plunger, is encased in a tube with a specialized solenoid coil. When activated, the plunger moves to open the valve while a spring retains the magnet in place when inactive. Different solenoid valve types and sizes exist, so this is a simplified overview.

A Plugnut

The plugnut in the solenoid valve functions as a barrier, preventing fluid from escaping when closed. An O-ring creates a seal between the plugnut and the solenoid magnet. Compatibility of materials and seals with the fluid is crucial for safety.

Different Forms of Electric Solenoid Valves

Solenoid valves are typically made from materials such as metal, plastic, brass, stainless steel, and aluminum. They generally come in two-way and three-way configurations, though four-way versions are also available. These valves can vary in size from miniature precision units to large push-pull, cartridge, and pilot valves. Special rotary solenoids are designed for high-flow industrial applications.

Solenoid Valve Applications

Solenoid valves are highly versatile and find use in many applications. An example is their use in water irrigation timer systems for commercial grounds. They also feature prominently in water purifiers and pneumatically operated valves, helping control air flow into actuators that move larger valves. In food processing plants, solenoid valves regulate propane gas for stoves, ranges, refrigeration systems, and filling machines.

In household applications, solenoid valves control water flow in washing machines and dishwashers. They are also used in air conditioning systems to manage air pressure. Car washes use solenoid valves to meter wax and soap into high-pressure pumps, as well as to control presoak, tire cleaner, or foam brush features. Additionally, these valves are integral to the automatic locking systems in door locks. In the dental and medical field, electric pneumatic valves help manage fluid pressure and flow direction.

Industrial Applications

In industrial settings, solenoid valves are crucial for controlling steam, water, air, and chemicals in hydraulic and pneumatic systems. Specialized wet-pin pressurized bore solenoids are utilized in hydraulic drilling operations. Moreover, explosion-proof solenoid valves are essential in oil drilling, refineries, and mining operations.

The Main Benefits of an Electric Pneumatic Valve (Solenoid Valve)

Electric solenoid valves offer numerous advantages for both industrial and plumbing applications. Some of their key benefits include:

• Easy network connectivity
• Rapid operation (quick open and close)
• Efficient remote and energy-saving functionality
• Cost-effective replacement parts
• Diverse application possibilities
• Enhanced safety due to controlled leakage
• Compatibility with both DC and AC voltage
• Versatile mounting options (vertical or horizontal)
• Highly responsive and lightweight
