What's the FESTO pneumatic electromagnetic valve is used in industry

Germany FESTO pneumatic electromagnetic valve for pneumatic components industry leading brands, products are mainly used in pharmaceutical industry, chemical industry, steel mills, power plants, cement plants, etc. Welcome customer calls in need rui machinery, we will give you the most reasonable price.
FESTO pneumatic electromagnetic valve opening and closing time to adjust.
FESTO pneumatic electromagnetic valve working principle:
FESTO pneumatic electromagnetic valve electromagnet drive pneumatic valve core is used to control the direction of the oil pressure, the direction of the hydraulic actuators to control the switch. Its advantage is simple operation, easy to implement remote control. Electromagnetic reversing pneumatic valve can realize two three links according to different requirements, two five-way, etc.
manipulation FESTO solenoid pneumatic valve with electromagnet is divided into two kinds of ac or dc:
the voltage, ac electromagnet, as a general rule, be v. Its characteristic is starting force is bigger, the reversing time is short, and cheap. But when binding or suction pneumatic valve core and make the iron core is not enough, the electromagnet is easy to burn out due to too much electricity, so the work reliability is poorer, action from time to tome, low service life.
normally, dc electromagnet voltage v. Its advantage is reliable, will not burn out by pneumatic valve core is stuck, long life, small volume, but starting force is relatively small ac electromagnet, and in the absence of dc power supply, rectifier equipment.
in order to improve the working reliability and life expectancy of electromagnetic reversing pneumatic valve, in recent years, both at home and abroad are increasingly widely used wet electromagnet, the electromagnet and slip between the pneumatic valve lifter does not need to seal, eliminates the friction of the O ring, its electromagnetic coil with engineering plastic cementing directly outside, no other metal shell, such not only ensure the insulation, and good for heat dissipation, so reliable work, impact is small, long service life.
FESTO pneumatic electromagnetic valve is used in what industry
FESTO pneumatic electromagnetic valve applicability
the FESTO, fluid pipeline must be and choose solenoid pneumatic valve series models in the calibration of the medium.
, selection of the temperature of the fluid must be smaller than the FESTO pneumatic electromagnetic valve of the calibration temperature.
, air compressor, FESTO pneumatic electromagnetic valve to allow the liquid viscosity, generally under CST, greater than the CST should be marked.
, working pressure difference, line the high pressure difference is less than. Should be chosen as ZS MPa, W, ZQDF, ZCM series and type of moving step by step straight acting; Differential pressure is greater than the minimum work. The MPa guiding type (optional Differential pressure type) FESTO pneumatic electromagnetic valve; Maximum working pressure difference should be less than FESTO pneumatic electromagnetic valve of maximum calibration pressure; General FESTO pneumatic electromagnetic valve is a one-way work, so should pay attention to whether there is a pressure difference, if you have installed check pneumatic valve.
, fluid cleanliness is not high, the filter should be installed in front of the FESTO solenoid pneumatic valve, general FESTO pneumatic electromagnetic valve on medium cleanness is better.
, pay attention to the flow aperture and take over diameter; FESTO pneumatic electromagnetic valve usually only switch two control; Conditions permit, please install bypass pipe, easy maintenance; Water hammer to
, pay attention to the environmental temperature on the FESTO pneumatic electromagnetic valve
, power source current and the influence of the consumed power should be selected according to the output capacity, power supply voltage generally + % to the left or right, must pay attention to communication when starting the VA value is higher.
