Solenoid Directional Control Valve Directs Flow of Fluids

Solenoid directional control valve can be used with one or more sources to direct the flow of various fluids into different directions.  It differs from manually and hydraulically pilot-operated valves as it is electrically controlled as opposed to using multifarious mechanical linkages or hulking hydraulic pilot lines for actuation of the valve. It is much easier to install solenoid valves and it saves on cost as well.

Solenoid directional valves are commonly used in circuits where 2-way, 3-way, and 4-way functions are required.  You can choose from direct acting and pilot operated valves that are available in poppet and spool configurations in the market.

Like pilot-operated valves, the direct acting valves do not require minimum pilot pressure for valve actuation. Pilot operated valves may offer the benefit of higher capacities. While the solenoid actuators operate in a highly efficient, push fashion. 

You can work creatively with the manufacturers to create you own style valve. A hybrid valve that incorporates a poppet style valve with an integral check valve can give you many benefits. The check valve allows free flow from port 2 to port 1 while the poppet can control flow between port 1 and port 3. To control motion and to provide load holding, this type of valve can be used in a circuit with a single acting cylinder.

As with most hydraulic machines, pistons are powered by a basic hydraulic pump. The pump is responsible for keeping a steady stream of pressurized fluid flowing into the system. There is no risk of leaks as the valves are designed to be leak proof. In any set up the valves are connected to several hoses that may lead to the hydraulic pump, a tank that feeds liquid back to the pump, and cylinder pistons. 

The piston rod that extends outside the cylinder is moved by a piston head inside the cylinder. Two different hoses feed the fluid to both sides of the piston. If the force is greater on one side, the piston moves to the other side. For changing the direction of force, you need to stop pumping oil to one side to start pumping it to the other side. This type of piston cylinder is called a hydraulic ram. Directional control valves direct the flow of liquids to these rams. The valve has a spool that moves back and forth, to block some inlet and outlet ports to open others.

Solenoid Directional Control Valve is used in Aerospace Projects

Solenoid directional control valve is used with hydraulic equipment and pneumatic machinery. They are a more cost effective option when compared to other valves. If your application requires the fluid to flow in different paths using a single source or multiple sources, these valves serve the purpose best.  You can use the control valve with both single and double acting cylinders.

Valves made by Interface Devices Inc. (IDI) are reliable enough to be used in aerospace projects. One can choose a valve based on the number of ports, number of positions, actuating methods and type of spool needed. IDI offers the patented “Zero-leak” 4-way solenoid valve for pressures up to 6000 psi.

The poppet-style valves eliminate the risk of leakage due to the strong aerodynamic seals used in its design. These are best for maintaining pressures for long durations with hydraulic equipment. One can save on cost, as the hydraulic supply will not require any electric power to function. All hydraulic machines require a heat exchanger due to the excessive amount of heat produced during operation. With IDI valves there are no such issues. The solenoid directional poppet-style valves work without generating much heat. 

The valves can be mounted on international standard sub plates: D03, NG6, and ISO 03. The D03 is available in many configurations to suit unique applications. Save on energy while getting pressures of up to 5000 psi (340 bar). The valves are designed to be simple and easy to use. The low maintenance valves can be used with multiple cylinders and you may also use more than one valve on one system.

 Interface Devices Inc. (IDI) is a reliable choice for gas boosters, pneumatic and hydraulic pumps and valves. The poppet-style valves are widely used for applications that require power workholding. Get fast and dependable delivery of liquids when you use the valves with E, H & P Series liquid pumps.

Solenoid Directional Control Valve Controls Flow of Liquids

Solenoid directional control valve is used to regulate and control the flow of liquids and gases. The non- mechanical valves rely on the condition of the controlled gas or liquid to open and close the same. Flow control valves can also be regulated by external monitoring devices such as pressure gauges or temperature gauges.

Flow control valves can be either a diaphragm or globe valve, or modified ball and gate valves. Hydraulic mechanism is used commonly to regulate a flow valve. The hydraulic mechanism makes the valves automatic as it does not require a sensor or an external mechanism to regulate the opening of the valve. A built-in relief mechanism is included in the hydraulic valves.  A wide variety of relief mechanisms are available to use the unsuitable conditions of the regulated liquid to operate the valve. 

Steam generators use a relief valve that is also called a pressure flow control valve. These valves help in prevention of steam explosions. When the steam goes unregulated, it can rupture the boiler tubing. When the steam reaches the desired high pressure, the pressure alone is enough to open the valve.

An altitude valve is another type of flow control valve which controls the volume of fuel and water tanks. A built-in switch is used to close the valve after the tank is full. The valve remains open when the water or fuel is filing the tank. 

Solenoid directional valves are an important part of hydraulic equipment and pneumatic machinery. They are used with one or more sources from where the fluid is directed in different paths. These valves are used in aerospace projects due to their highly reliable built and design.  You can use these durable valves with single or double acting cylinders. These valves can be chosen according to the number of ports, number of positions, actuating methods and type of spool required. The zero leakage valves feature aerodynamic seals that are most durable.
