Model: IFD 258-5/1W, IFD 258-10/1W, IFD258-3/1W

IFD 258-5/1WI、 IFD 258-10/1WI、 IFD258-3/1WI 等

(There are many models available, please contact us for detailed models)

Working voltage: 230V, 120V

IFD 258 is used to control the ignition and flame monitoring of burners, and can control burners with combustion air

It can also control atmospheric burners and participate in other control functions in conjunction with PLC. Burner controller and

The ignition transformer can be integrated into one ignition box, and our company can provide integrated supply

Functional Description

When the flame monitor is powered on, it enters the working state. If a flame is detected in the combustion device, the flame microampere signal sent back by the flame sensor is amplified through an internal amplification circuit to drive the relay inside the flame monitor. The relay nodes can be used to participate in more system control.

In a multi flame control system, all flame signals are interlocked and sent to PFU760 through another series of flame monitors to simultaneously control these burners

Gas pipeline safety and pressure stabilization system: including stabilizing valve, filter, shut-off valve, safety release valve, and pressure switch.

Electromagnetic valve series: including electromagnetic straight through valve and electromagnetic butterfly valve.

Electric gas shut-off valve series

Air/gas proportional valve

Electric gas regulating butterfly valve

Electric air conditioning butterfly valve: including normal temperature valve and high temperature valve.

Gas burner: including high-speed pulse burner, air preheating burner with radiation tube, gas burner with temperature regulating air, etc.

Suitable for combustible gases such as natural gas, liquefied gas, city gas, and mixed gas. Flame shapes: short flame, long flame, and flat flame.

Method for quickly determining the quality of solenoid valves on site

Firstly, check if there is a malfunction in the solenoid coil of the solenoid valve

Give the signal to open or close the two position valve on DCS, and then check whether the solenoid valve is powered on or off. Generally, listen to the sound on site. If you can't hear it, then there must be a problem with the coil. As for the solenoid valve itself, is there a problem? (Explanation below)

If there is a problem with the electromagnetic coil, first check the wiring to see if there is any loose connection or short circuit. If there is no problem with the wiring, it means that the electromagnetic valve coil is burnt out. Remove the wiring of the electromagnetic valve and measure it with a multimeter. If there is an open circuit, the electromagnetic valve coil is burnt out.

The reason is that the coil is damp, causing poor insulation and magnetic leakage, resulting in excessive current inside the coil and burning out. Therefore, it is necessary to prevent rainwater from entering the solenoid valve. In addition, if the spring is too hard, the reaction force is too large, the number of turns in the coil is too small, and the suction force is not enough, it can also cause the coil to burn out.

If the coil is good, it is a problem with the solenoid valve itself

Generally, the valve can be manually adjusted from 1 to 0 position using a straight line to open it. If it can be opened, it indicates that it is indeed a problem with the coil, and a new coil can be used. If it cannot be opened, the solenoid valve should be removed to see if the valve core is stuck or if there are impurities blocking it. If cleaning is correct, CCL4 should be used.

However, considering that there are no conditions on site, gasoline can be used, even if there is no water available. After cleaning, the on-site instrument air can be used to blow dry. When disassembling, it is important to remember the order of each component. If not careful, it is easy to make mistakes during installation. Even if you clean the solenoid valve properly, even if it is already open, it still cannot be opened!
