Voltage is 220V.
AC110V DC24V DC12V AC24V is also available
Underwater dedicated solenoid valve.
Solenoid valve selection should first turn to follow the four principles of security, reliability , applicability , economy, followed by six according to site conditions (iePipelineParameters , fluid parameters , pressure parameters , electrical parameters , action , special requirements for selection ) .
Selection based on:
First, according to the solenoid valve conduit preferences : Path specifications ( ie DN), Interface
1, according to the pipe diameter spot size or flow requirements to determine the diameter (DN) size.
2, the interface mode, general > DN50 flange interface to select , ≤DN50 can freely choose according to user needs .
Second, according to the fluid parameter selection solenoid valve : material , temperature set
1 , corrosive fluids : better to use corrosion-resistant solenoid valve and fullStainless steel; Clean fluid consumption : better to use food-grade stainless steel solenoid valve.
2, the high-temperature fluids : To opt for high temperature electrical materials and sealing materials solenoid valve , but also to choosePistonStructure type.
3, the fluid state : large to have a gas, liquid or mixed state , especially when the diameter is greater than DN25 orders must be distinguished .
4 , fluid viscosity : usually 20cSt the following can be arbitrarily chosen , if the viscosity is high, will have to use high viscosity solenoid valve.
Third, according to the parameter selection pressure solenoid valve : the principle and structure varieties
1 , nominal pressure : This parameter with otherCommonValveThe meaning is the same, is based on nominal pipe to be.
2 ,Working Pressure: If the working pressure is low then you must use direct action or step direct-acting principle ; when the minimum working pressure 0.04Mpa direct acting above , step by step direct-acting , pilot can be selected.
Fourth, the voltage selection : voltage specification should be preferred AC220V, DC24 is more convenient.
Five , according to continue to work to select the length of time : normally closed, normally open , or sustainable electricity
1, when the solenoid valve takes a long time to open , and the duration of the extra time off should be used normally open .
2 , if the open time is short or open and no more off time , the selection normally closed .
3 , however , some conditions for security , such as the furnace , kiln flame monitoring , it is not normally open election , to be elected to long-term power type .
Six , according to the environmental requirements to select Accessibility: explosion-proof, waterproof fog , water washout , diving
