Solenoid Valve

What is Solenoid Valve?

What is a solenoid valve and where is it used? Solenoid valves help control the flow of liquid or gas. These valves are included with the equipment so that the equipment can be used safely and efficiently. What a solenoid valve does is use a plunger to open or close the valve, either allowing the fluid to flow or sealing it without any leakage. This is an extremely important process in the automation of fluid and gas control. This is the clearest answer that can be given to the question of what are solenoid valves.

Solenoid valves; It is manufactured in two types as normally closed (to open the closed valve when it receives energy from the coil) and normally open (to close the open valve when it receives energy from the coil).

What is a Normally Open Solenoid Valve?

Normally Open Solenoid valve initially allows the passage of fluid. In order to close the valve, the coil moves with the electric current coming to the coil, pushing the core down and closing the mouth of the orifice hole, and in this case, the pressure inside increases gradually and pushes the diaphragm down and closes the orifice through which the fluid passes. In a short time, the pressure spreads homogeneously on the diaphragm and the pressure higher than the pressure of the fluid prevents the fluid from lifting the diaphragm, so the valve is in the closed position. All this happens in a very short time. Our product is designed to get the best efficiency.

What is a Normally Closed Solenoid Valve?

Normally Closed Solenoid valve initially allows the passage of fluid. In order for the valve to open, the coil moves with the electric current coming to the coil, pulls the core upwards and opens the mouth of the orifice hole, and thus, the fluid under high pressure advances to the outlet quickly from the bypass hole. With this progress, the pressure inside drops very quickly and a pressure difference occurs inside. Due to this difference, the diaphragm overcomes the spring force and rises upwards and fluid passage is allowed, so the valve is in the open position. All this happens in a very short time. Our product is designed to get the best efficiency.

What is AC and DC in Solenoid Valves?

In practical design and application, there are two main types of common power supply for solenoid valves: AC (like 110V, 220V) and DC (like 12V, 24V). Due to the high supply voltage in the transmission process and the small voltage loss of the cable resistance, the AC power supply will not cause the solenoid valve drive voltage to be insufficient, so that the solenoid valve cannot work. But 220 V AC cable cannot be mixed with other device signal cables and has to be laid separately, which brings a lot of difficulties in design and construction. There is no need to lay the 24V DC supply cable separately, but it is better to calculate the solenoid supply voltage before deciding to use a 24V DC solenoid valve, especially in case of long power supply distance.

What Is Solenoid Valve Used For?

Users wonder why solenoid valves are used and whether systems need solenoid valves. To regulate fluids in the system, most flow control applications require starting or stopping flow in the circuit. This is usually done using an electrically controlled solenoid valve. Because solenoid valves are solenoid driven, they can be remotely located and operated with simple electrical switches.

In fluids, solenoid valves are the most commonly used control components. They are often used to seal, release, dose, disperse or mix liquids. As a result, they can be found in a wide variety of applications. Solenoids are known for their fast and safe switching, long service life, high reliability, low control powers and small size. We wanted to explain why solenoid valves are used in this way.

What are Solenoid Valve Prices?

Solenoid valve prices vary by models and brands. The material used, the general performance of the valve, the type of valve usage, how many outlets it has, how fast the valve can move and the temperatures at which it will be used are among the factors affecting solenoid valve prices. At the same time, various factors such as solenoid valve supplier ratios, market sector and profit margins also cause differences.

What are the Advantages of Solenoid Valve?

Solenoid valves have gone through a constantly evolving design process to improve and improve their functionality over many years, creating a reliable and efficient valve. The solenoid valve is an incredibly versatile option, especially in automated systems where the operation must be done remotely, such as solenoid valve applications with toxic liquids. The opening and closing times of a solenoid valve make it the ideal solution for many applications where speed is a critical factor. Some important advantages of solenoid valves are summarized below:

• Low energy use
• Remote-controlled
• Cost-effective for maintenance and service
• Compatible with AC and DC voltages
• Extremely fast on and off times
• Ability to work in extreme temperatures
• Security external leak block
• Works both vertically and horizontally

Solenoid valve applications are extremely diverse thanks to their versatility.

Where Are Solenoid Valves Used?

Solenoid valves are used in fluid power pneumatic and hydraulic systems to regulate cylinders, fluid power motors and larger industrial valves. Automatically controlled solenoid valves are also used in automatic irrigation sprinkler systems. Solenoid valves are used to control water flow in household washing machines and dishwashers. They are also commonly seen in paintball pistol triggers where they are used to activate the CO2 hammer valve. Solenoids are the most common name for solenoid valves.

Solenoid valves can be used for a variety of industrial applications, including general on-off control, calibration and test stands, pilot plant control loops, process control systems and OEM applications.

How Does the Solenoid Work?

A solenoid works by generating an electromagnetic field around a moving core called an armature. When forced to move by the electromagnetic field, the action of that armature opens and closes valves or switches and converts electrical energy into mechanical motion and force.

What Does a Closed Solenoid Valve Mean?

A normally closed solenoid valve is a way to control the flow of liquid or gas. This valve is similar to other solenoid valves in that it stops or starts the flow of fluid, but differs in the process it uses to do so. When a normally closed solenoid valve is not powered, the piston drops down and effectively seals the valve and blocks the flow of liquid or gas. When the normally closed solenoid valve is energized or energized, the magnetic field causes the piston to rise. This opens the valve and allows fluid or fluid flow to pass.

Why Does the Solenoid Valve Get Hot?

When the solenoid valve coil is operating (electric), the iron core is pulled to form a closed magnetic circuit. That is, it is normal for the solenoid to heat up when the inductance is at its maximum design state. However, if the iron core cannot be drawn properly when electrified, the solenoid inductance will decrease, the impedance will decrease, and the current will increase, which will cause excessive current in the coil and affect its service life. Therefore, oil pollution, impurities and deformation will hinder the movement of the iron core and slow down their movement when the power is turned on. Even the iron core may not be drawn. As a result, the coil impedance is lower than its normal state when energized, thus causing the solenoid valve coil to heat up or heat up.

How to Identify Solenoid Valve Failure?

Solenoid valve malfunctions are understood if there are situations such as the failure of the solenoid valve not opening or closing correctly, the coil burned, melted or cold when the power is on, the occurrence of solenoid valve leaks.

What Happens If The Solenoid Valve Is Broken?

• Exceeding the pressure rating of the solenoid valve can damage the valve components. Tears in the diaphragm, damage to the valve body and armature tubing are often an indication of excessive pressure.
• Deformation of diaphragms, gaskets and o-rings can be caused by ambient temperature outside the valve’s specified temperature range.
• Sediment or particles entering the valve may affect valve operation. This contamination of gaskets and diaphragms can cause the valve not to close properly. If a valve is leaking, it is an indication that foreign matter is preventing the valve form from sealing properly.
• Corrosion of the metal components of a solenoid valve or deterioration of the seals and diaphragm can be caused by a compatibility issue with the media and valve materials. Pollution in the environment can also cause such malfunctions.

Why Does the Solenoid Valve Deteriorate?

Some reasons why the solenoid valve fails include lack of power in the solenoid coil, burned coil, incorrect voltage, pressure differences (too high or too low), and contamination of the membrane, valve seat, or tubing. In addition, when we think about why the solenoid valve is broken, it should not be forgotten that a vital part may be missing or damaged.

How Many Volts Does the Solenoid Valve Operate?

Solenoid valve is an electromagnetic valve used to control the flow of liquids and gases. By applying electrical energy to the coil on the solenoid valve, the position of the valve (normally closed, normally open) is changed. The electricity coming to the coil has different energies such as 220V, 110V, 24V, 12V, 6V (AC, DC).

What are the Solenoid Valve Dimensions?

Solenoid valve dimensions vary between 1/8” – 2” depending on the valve model, usage type and material.

How to Clean Solenoid Valve?

Dirt or dust collected in the office can be one of the factors that cause trouble or error. If these reasons can be recognized, it will be sufficient to clean the solenoid valve and use a new filter. At this point, you may be thinking, what is the solenoid valve filter? The filter separates the dirt and dust formed in the valve from the fluid. In this way, it both increases the efficiency of the valve and delays possible problems as much as possible.

You can use chemicals specific to the filter to clean the solenoid valve. These chemicals not only clean the particles accumulated in the filter, but also open the blockages. You can clean the outside of the separate valve and other parts with a soft cloth.
