Сonnection of electromagnetic valves to the power supply is carried out by means of output wires. The feed of electromagnetic valves comes true from the network of direct-current by tension 27 В. Electromagnetic valves are made in the following versions: - normally open with one coil of control; - normally open with two coil of control; - normally closed with one coil of control; - normally closed with two coil of controlt. Еlectromagnetic valve consists of electric and hydraulic parts and is electromagnetic valve with a concentric winding and anchor in electric part and a movable rod and ball in the hydraulics. When give tension, an anchor through the rod moves the ball, which opens or closes communicating channels in hydraulic part of valve. This changes the direction of working fluid flow through the еlectromagnetic valve. Cooling method - the сonvention. Performance - closed. Inclusion of electromagnetic valve is produced by the direct inclusion from two the wire network of direct-current. The duration of one inclusion from 5 second to 15 hours. Work of electromagnetic valve is based on connection of line "highway" with lines "pumping" or "drain" depending on the presence or absence of supply voltage on the winding of electromagnetic valve with help of shut-off valves ball-type. In a normally open electromagnetic valve to control the flow of hydraulic fluid used one ball, normally closed - two balls. Operating position of the electromagnetic valve in space - arbitrary.5481 Product Description popup.authors Лиховченко Дмитро Віталійович popup.nrat_date 2020-04-02 Close
