However, when there is the valve switch, it is also a control cable, no matter whether DCS has the guard grating or not. If you machine has an electric solenoid gas valve (inside machine cabnet). DCS outputs one DO to control the contact of one relay and is connected with the power supply and solenoid valve in parallel. Dual voltage, can be used with both 110V and 220V, currently set up for 220V. In terms of the pneumatic valve, the solenoid valve generally adopts the single coil. If there are position switching-on and switching-off feedback signals, use one cable (4*1.5) or two cables (2*1.5). Under this condition, there is only one (2*1.5) cable. In other words, the coil of the relay is 24V DC, and the contact is 220V AC. The output of DCS generally features electrical independent contact, which requires the intermediate relay for isolated conversion. As a matter of fact, it controls the on and off of the solenoid valve. Take the DCS to control switching of pneumatic valve is very easy. Does this mean there are two cable lines? If there is the valve position switch, how will the wiring become? Does the valve position switch require independent power supply? Then, how much cable is required in total? The DCS outputs a DO signal and requires one 220V power supply cable. Take the 220V AC pneumatic valve for example. Either in terms of 24 V DC or in terms of 220 V AC, there are two wires which can lead to generation of magnetism for the coil (which is the power supply wire), and the other one is for ground connection. The solenoid valve on the pneumatic valve is generally three-wired. Is it that the solenoid valve on the pneumatic stop valve can be two-wired, three-wired or four-wired? Here are some problems for your reference.ġ. This effectively seals the valve, preventing the gas or liquid from flowing through.Although the wiring of solenoid valve is simple, but poeple still encouter problems when wiring the solenoid valve to other devices. Once the coil on the plunger is energized, however, the magnetic field causes the plunger to rise. When a normally open solenoid valve is not powered, the plunger is down, which means that a flow is allowed through the valve. Coil Voltage Option: 12V DC, 24V DC, 24V AC, 110V AC, 220V AC. This valve differs in the way that the flow is started or stopped. 2 Inch High Pressure General Purpose Brass Electric Solenoid Process Valve Normally. A normally open solenoid valve controls the flow of gas or liquid. The basic function of the normally open solenoid valve is the same. This valve works slightly different than a valve that is normally closed. One commonly used solenoid valve is one that is normally open. This promotes safe and efficient use of the equipment.īecause solenoid valves are so important to the automation of fluid and gas control, it's vital that the right solenoid valve be used for a certain function. This part allows operators to turn the flow of the fluid or gas on and off without fear of leaks. Have you ever wondered how fluid and gas can be contained and directed through equipment without any leaks? Solenoid valves are important parts of any equipment that uses fluid or gas.
