contact information of ignition transformer for imported combustion engine of Kizilsu and Kirgiz select solenoid valve according to pipeline parameters: diameter specification (i.e., DN), interface method

1) determine the diameter (DN) size according to on-site pipeline inner diameter size or flow requirements; Contact information of ignition transformer of imported combustion engine in Kizilsu and Kirgiz

3) AC voltage fluctuation is usually +%10%- 15%, DC allowable ±%10, if out of tolerance, voltage stabilization measures must be taken

3) working differential pressure: if the working differential pressure is above 0.04MPa, the indirect pilot type can be selected; If the working pressure difference is close to or less than zero, the direct acting type or step-by-step direct type must be selected

2) interface mode: generally, flange interface shall be selected for>dn50, and it can be freely selected for ≤ DN50 according to the needs of users

2. Select the solenoid valve according to the fluid parameters: the material and temperature group

must pay attention to the high VA value during AC starting,

6) the medium temperature should be selected within the allowable range of the solenoid valve

2. Pipeline parameters

1) select the valve port and model according to the requirements of medium flow direction and pipeline connection mode

2) select the nominal diameter according to the flow and valve Kv value, or the same as the pipe inner diameter

1) corrosive fluid: corrosion resistant solenoid valve and all stainless steel should be selected; Edible ultra clean fluid: food grade stainless steel solenoid valve should be selected

2) high temperature fluid: select the solenoid valve made of high temperature resistant electrical materials and sealing materials, and select the piston structure type

2) 24V shall be preferred for voltage specification

4) when the medium cleanliness is not high, the backwash filter valve should be installed in front of the solenoid valve. When the pressure is low, the direct acting diaphragm solenoid valve can be selected

5) if the medium is in directional flow, and reverse flow is not allowed, it needs to be in two-way flow

3) fluid state: it must be distinguished from gas state, liquid state or mixed state, especially when the caliber is greater than DN25

4) fluid viscosity: generally, it can be arbitrarily selected below 50cst. If it exceeds this value, high viscosity solenoid valve shall be selected

3. Selection of solenoid valve according to pressure parameters: principle and structure type

AC and DC solenoid valves are selected respectively according to the type of power supply. Generally speaking, the AC power supply is easy to access

5) if the environmental space is limited, the multi-functional solenoid valve shall be selected, because it eliminates the bypass and three manual valves and is convenient for maintenance

1) nominal pressure: this parameter has the same meaning as other general valves and is determined according to the nominal pressure of the pipeline

2) working pressure: if the working pressure is low, the direct acting or step-by-step direct acting principle must be selected; When the working pressure difference is above 0.04MPa, the direct acting type, step-by-step direct acting type and pilot type can be selected

4. Electrical selection: AC220V and DC24 shall be preferred for voltage specification as much as possible, which is more convenient

5. Select according to the duration of continuous operation: normally closed, normally open, or continuously energized

1) when the solenoid valve needs to be opened for a long time and the duration is longer than the closing time, the normally open type shall be selected; Contact information of ignition transformer for imported combustion engine in Kizilsu and Kirgiz

2) 24V shall be preferred as far as possible if the voltage specification is not deformed

applicability:

1. Medium characteristics

1) different types of solenoid valves are selected for gas, liquid or mixed state

2) the standard requirements such as design standard 3.9 shall be produced in different specifications of medium temperature, otherwise the coil will burn off and the seal will be aged, seriously affecting the service life

we can stand the supervision of users. 3) the medium viscosity is usually below 50cst. If it exceeds this value, when the diameter is large and the material cost accounts for about 30% of the total cost, use the multi-functional solenoid valve; When the diameter is less than 15mm, use high viscosity solenoid valve
