Contact the following: Fax: 0577-61787959, phone: 18968923599,13968712616,15381518281, landline: 0577-61787959 QQ Contact: 478988506,1137357510 solenoid valve is used to control fluid automation infrastructure components, belonging to the actuator; not limited to hydraulic, pneumatic. Solenoid valve for controlling the gas flow direction, a mechanical plant are usually controlled by hydraulic cylinder, so it will use the solenoid valve. Solenoid valve selection and installation precautions selection basis: First, according to the solenoid valve pipeline parameters: Path specification (ie DN), Interface 1, in accordance with the pipe diameter spot size or flow requirements to determine the diameter (DN) Dimensions . 2, interface mode, general> DN50 flange interface to select, ≤DN50 can be free to choose according to the user. Second, according to the solenoid valve fluid parameters: material, temperature group 1, corrosive fluids: better to use corrosion-resistant stainless steel solenoid valve and; edible clean fluids: should use food-grade stainless steel solenoid valve. 2, the high temperature fluid: To select use of high temperature electrical materials and sealing materials solenoid valve, and to select the type of piston-type structure. 3, the fluid state: Queen to have a gaseous, liquid or mixed state, especially when diameter greater than DN25 orders must be distinguished. 4, fluid viscosity: usually 50cSt the following can be arbitrary choice, if exceeded, will have to use a high viscosity solenoid valve. Third, according to the solenoid valve pressure parameters: 1 principle and structure of varieties, nominal pressure: This parameter is the other meaning is the same as the common valve, based on nominal pipe to be. 2, the working pressure: if the work pressure is low, you must use direct action or step direct-acting principle; minimum working pressure 0.04Mpa than when direct acting, step by step direct-acting, pilot can be selected. Fourth, the electrical options: voltage specification should be preferred AC220V, DC24 is more convenient. Fifth, continue to work according to the length of time to choose: normally closed, normally open, or sustainable electricity. 1, when the solenoid valve takes a long time to open, and duration of extra time should be used to close the normally open type. 2, if you open a short time or on and off much of the time, then select normally closed. 3, but some conditions for security, such as the furnace, furnace flame monitoring, you can not select normally open, to be elected long-energized. Sixth, according to environmental requirements select the auxiliary function: Explosion, check, manual, water fog, water washout, diving 1, explosive environment: to choose the appropriate level of explosion-proof solenoid valve.
