SMC 5-Way Solenoid Valve Working Principle: Available in normally closed and normally open types. The normally closed type is closed when de-energized. When the coil is energized, electromagnetic force causes the moving iron core to overcome the spring force and attract the stationary iron core, directly opening the valve and allowing the medium to flow. When the coil is de-energized, the electromagnetic force disappears, and the moving iron core resets under the spring force, directly closing the valve port and preventing the medium from flowing. It has a simple structure, reliable operation, and works normally under zero pressure difference and micro-vacuum. The normally open type is the opposite. For example, SMC solenoid valves with a flow diameter smaller than φ6. SMC solenoid valves use a single-stage opening and a single-stage opening mechanism, with the main valve and pilot valve opening the main valve port directly through electromagnetic force and pressure difference in stages. When the coil is energized, electromagnetic force is generated, causing the moving and stationary iron cores to attract each other. The pilot valve port opens and is located on the main valve port, with the moving iron core connected to the main valve core. At this time, the pressure in the upper chamber of the main valve is relieved through the pilot valve port. Under the combined action of pressure difference and electromagnetic force, the main valve core moves upward, opening the main valve for media flow. When the coil is de-energized, the electromagnetic force disappears. The moving iron core closes the pilot valve port under its own weight and spring force. The media then enters the upper chamber of the main valve core through the balance hole, increasing the pressure in the upper chamber. Under the action of spring reset and pressure, the main valve closes, cutting off media flow. The structure is reasonable, the operation is reliable, and it works reliably even at zero pressure difference. Examples include: ZQDF, ZS, and 2W.

The SMC5 solenoid valve has a sealed chamber with through-holes at different positions, each leading to a different oil pipe. Inside the chamber is the valve itself, flanked by two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. By controlling the movement of the valve body, different drain holes are blocked or opened. The inlet hole is normally open, allowing hydraulic oil to enter different drain pipes. The oil pressure then pushes the piston of the hydraulic cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Thus, controlling the current to the electromagnets controls the mechanical movement. Solenoid valves are divided into normally closed and normally open types; normally closed types are generally preferred, opening when energized and closing when de-energized. However, normally open types should be used when the opening time is long and the closing time is short.

The SMC5 solenoid valve is an actuator used in industrial process automation control systems. Upon receiving an electrical control signal, it automatically opens or closes, achieving the control of the flow or regulation of liquid media in pipelines. Stainless steel solenoid valves are widely used in production and research departments of textiles, printing, chemicals, plastics, rubber, pharmaceuticals, food, building materials, machinery, electrical appliances, and surface treatment, as well as in daily life facilities such as bathrooms, canteens, and air conditioning. Solenoid valves are mainly used for controlling liquid media such as corrosive liquids, purified liquids, and edible liquids.

When the SMC5 solenoid valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body. Therefore, the pressure drop through this valve is very small, resulting in good flow control characteristics. Electric ball valves have two sealing types: resilient seal and metal seal. In resilient seal valves, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate. Valves with metal seals generally have a longer lifespan than those with resilient seals, but it is difficult to achieve a complete seal. Metal seals can withstand higher operating temperatures, while resilient seals have the disadvantage of being temperature-limited. If an electric ball valve is required for flow control, it is important to accurately select the valve size and type. The construction principle of electric ball valves is particularly suitable for manufacturing large-diameter valves. Electric ball valves are widely used not only in general industries such as petroleum, gas, chemical, and water treatment, but also in cooling water systems of thermal power plants. Commonly used electric ball valves include wafer-type and flanged-type valves. Wafer-type electric ball valves are connected between two pipe flanges using double-ended bolts, while flanged-type electric ball valves have flanges on the valve itself, which are bolted to the pipe flanges. The strength performance of a valve refers to its ability to withstand the pressure of the medium.

The working principle of the SMC5 solenoid valve: When energized, the electromagnetic force opens the pilot orifice, causing the pressure in the upper chamber to drop rapidly, creating a pressure differential around the closing element (higher at the bottom and lower at the top), pushing the closing element upwards and opening the valve. When de-energized, the spring force closes the pilot orifice, and the inlet pressure quickly enters the upper chamber through the bypass orifice, creating a pressure differential around the closing element (lower at the bottom and higher at the top), pushing the closing element downwards and closing the valve. Features: It has a very high upper limit for fluid pressure, but the fluid pressure differential condition must be met. Currently, commonly used solenoid valves sold in China include over a dozen varieties from the DV (DVF), PGA, PEB (PESB), and BPE series, with diameters ranging from 3/4" to 3". They are mainly used in agriculture, landscaping, golf courses, industrial dust control, and fountains. Most commonly used solenoid valves are diaphragm valves. Their working principle is as follows: the valve body is divided into upper and lower chambers with a diaphragm in between. Under the same water pressure, the pressure difference created by the different force-bearing areas on the upper and lower parts of the diaphragm achieves the purpose of cutting off the water flow.

SMC 5-way solenoid valve main features: Corrosion resistance: Most parts are made of stainless steel or cast stainless steel, providing excellent corrosion resistance. Heat resistance: The electromagnetic components and seals all use special high-temperature resistant electrical and sealing materials, and effective heat insulation measures are adopted. Wear resistance: Reasonable material selection; the valve cup and guide sleeve cleverly utilize the lubrication effect of the fluid to reduce wear. Reliability: Simple and compact structure, combining the advantages of direct-acting and pilot-operated indirect solenoid valves, allowing reliable operation even under low pressure differential or zero pressure differential conditions.

The SMC5 solenoid valve is a step-by-step, direct-operated solenoid valve. Depending on its on/off state when de-energized, it can be divided into normally closed and normally open solenoid valves. In a normally closed solenoid valve, when the coil is energized, the armature, under electromagnetic force, first drives the secondary valve to open. The main valve then opens under the combined pressure difference of the medium and electromagnetic force. When the coil is de-energized, the armature returns to its original position, and the main and secondary valves close tightly using the medium pressure. In a normally open solenoid valve, when the coil is energized, the armature moves downward under magnetic force, pushing the secondary valve plug downward until it presses against the secondary valve seat, closing the secondary valve. Since the pressure difference across the main valve cup tends to be equal, the main valve cup is tightly sealed by magnetic force and its own weight, closing the valve.

The SMC5 solenoid valve has a simple structure, small size, and light weight, consisting of only a few parts. It can be quickly opened and closed with just a 90° rotation, making operation simple. This valve also has excellent fluid control characteristics. When a butterfly valve is in the open position, the thickness of the butterfly plate represents the resistance to the medium flowing through the valve body. Therefore, the pressure drop across the valve is very small, resulting in good flow control characteristics. Butterfly valves have two sealing types: resilient seal and metal seal. In resilient seal valves, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate. Valves with metal seals generally have a longer lifespan than those with resilient seals, but achieving a perfect seal is more difficult. Metal seals can withstand higher operating temperatures, while resilient seals are limited by temperature. If a butterfly valve is required for flow control, the most important factor is correctly selecting the valve size and type. The structural principle of butterfly valves is particularly suitable for manufacturing large-diameter valves. Butterfly valves are widely used not only in general industries such as petroleum, gas, chemical, and water treatment, but also in cooling water systems of thermal power plants. Commonly used butterfly valves include wafer-type butterfly valves and flanged butterfly valves.
