Zero pressure diaphragm solenoid valve.solenoid valve

Two - way solenoid valve is a step - by - step direct pilot solenoid valve. Can be divided into normally closed solenoid valve and normally open solenoid valve according to the state of the power off. After the coil of the normally closed solenoid valve is powered on, the armature first drives the auxiliary valve plug to lift under the action of electromagnetic force, and the fluid on the valve cup of the main valve flows away through the auxiliary valve. Reduces the pressure acting on the main valve cup. When the pressure on the main valve valve cup is reduced to a certain value, the armature drives the main valve valve cup and uses the pressure difference to make the main valve valve cup open medium flow. The electromagnetic force disappeared after the coil was cut off. The armature fell and reset due to its dead weight.

Diaphragm type solenoid valve features:

Low noise, no water hammer impact, no shaking sound;

Smooth work, large flow;

High reliability, long life;

Replace the pilot head and coil can be used as explosion valve;

Small body, beautiful appearance, coil power directly start the valve core;

Valve body installation direction unlimited, suitable for medium pressure, low and medium pressure pipeline system;

Control mode of solenoid valve --

Normally closed type: power off, power on;

Normally open type: power on, power off;

Diaphragm type solenoid valve is used in all kinds of normal temperature, normal pressure occasions, suitable for the automatic control of water or liquid, gas as the medium pipeline; Widely used in environmental protection water treatment, sewage treatment, water plant, central air conditioning, electric power, mining, petrochemical, biological pharmaceutical and mechanical equipment and other industries, is the first choice of automation control engineering, project transformation and equipment matching products.

Packing of Standard Packing:
