The self-hold electromagnetic valve working principle and technical parameters and USES

Self-hold electromagnetic valve of the working principle and technical parameters and USES electromagnetic valve experts keep working principle of electromagnetic valve electromagnetic pilot valve adopts mechanical self-locking function of memory has double the forerunner of the structure of the type. When coil component 'B' electricity, electromagnetic valve opens, then the power, the electromagnetic valve as Chang Tong state, when the part 'A' coil electricity, electromagnetic valve closed, then power, the electromagnetic valve is normally closed state. If coil 'A', 'B' electricity at the same time, the electromagnetic valve as Chang Tong state, coil also won't burn out. This valve can be applied to switch cycle than long work environment. Diaphragm technology parameters of the nominal diameter - mm nominal pressure. MPa working pressure difference. ~. MPa fluid circulation medium water, air, low viscosity oil ( Less than the engler °) , no corrosive gas medium temperature ℃ ℃ ~ ( Don't freeze) Allow ℃ temperature voltage ACV ACV ACV DCV listed listed listed DCV consumed power AC AV DC W piston structure n electromagnetic part, seal all adopts special high temperature resistant electric material and seal materials, and adopt the effective heat insulation measures n structure is simple, compact, combines the advantages of direct acting and pilot indirect solenoid valve, under the condition of low pressure or differential pressure is zero can also be reliable work n material selection is reasonable, the valve and guidance suite skillfully use of fluid lubrication, reducing wear and improve the life. Piston technical parameters such as the steam, distilled water as the working medium of gas liquid and other non corrosive fluid temperature ℃ (or less Conventional) ≤℃( High temperature) Nominal pressure Mpa. Conventional) 。 /。 The above ( High pressure) Work pressure differential Mpa. 。 。 。 ( Conventional) 。 。 /。 。 /。 。 The above ( High pressure) Since keeping type solenoid valve of the purpose of this valve is a industrial process automation control system with actuator. It in an electronic signal automatically switched on or off, after the implementation of pipeline fluid on and off for two type of automatic control and remote control. This series solenoid valve can be widely used for textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments and bathroom, dining room, air conditioning automatic control system, etc.
