Do you know the advantages of the imported normally open solenoid valve is reflected in which aspects?

Imported normally open solenoid valve as many manufacturers commonly used in many types of imports, in many devices are reflected, then compared with the non-imported normally open solenoid valve, the advantages of imports and in what areas?

A, the scope of application

The liquid in the pipeline, should be consistent with the selected solenoid valve series model of the correction material; oil temperature should be lower than the selected solenoid valve calibration temperature; common solenoid valve allows the fluid viscosity less than 20 CST, more than 20 CST should be marked its viscosity; in the case of working pressure difference, pipeline pressure difference is less than 0.04 MPa, direct drive and step-by-step direct drive, ZS,2 W, ZQDF, ZCM series, liquid with normally open solenoid valve working pressure above 0.04 MPa; can choose control type (differential voltage) solenoid valve; high working pressure difference must be less than the large calibration pressure of the solenoid valve; usually the solenoid valve is one-way operation, so pay attention to whether there is a reverse pressure difference, if there is a reverse valve installed; if the liquid cleanliness is low, the solenoid valve should be installed in front of the screen, usually The use of electromagnetic type; specify the degree of cleanliness of the valve medium; pay attention to the role of the ambient temperature on the solenoid valve; pay attention to the flow diameter and diameter of the nozzle; usually, the solenoid valve is controlled by only two switches; in the case of conditions permitting, the installation of bypass piping to facilitate maintenance; in the event of water hammer phenomenon, the need to customize the opening and closing of the solenoid valve regulation.

Second, stable

smc normally open solenoid valve inlet is divided into two kinds of normally open and normally open; usually choose normally closed type, open power, cut off power. However, if the opening time is long and the closing time is short, then choose the normally open type, life test, manufacturers are usually type testing, or that there is no domestic special solenoid valve, so in general, it is recommended to choose imported solenoid valves, such as the United States MILLER Miller, the United States ASCO, Germany HERION HELLON, etc., have a high reputation in the international arena.

Third, the guarantee

Ordinary imported solenoid valves do not have a waterproof function. Electronically controlled normally open solenoid valve in the case of conditions do not allow, choose the waterproof type. The plant can be produced according to the order.

High standard input solenoid valve must exceed the high pressure in the pipeline, otherwise it will shorten the life or other accidents, corrosive liquids to all use stainless steel, highly corrosive liquids to use SLF solenoid valve, explosive environment to choose the appropriate explosion-proof products.
