Normally open solenoid valve basic expertise explained

A, safety performance

1, corrosive media: it is appropriate to use the tetrafluorine rod or full normally open solenoid valve, Korakuen solenoid valve manufacturers for strong corrosive substances must be used to protect the pulse damper type.

2, neutralized substances: alloy copper can be used for the valve shell material solenoid valve, compressor normally open solenoid valve otherwise the valve shell often rust chips fall down, especially in the gesture is not repeated. Ammonia can not use copper valve.

3, flammable natural environment: be sure to use matching grade products, outdoor or dusty places should be selected explosion-proof dirt-resistant type solenoid valve.

4, solenoid valve pounds should be higher than or exceed the Z large pressure in the pipe.

Second, the scope of application

1、Material characteristics.

1.1, the quality of gas, liquid or mixed conditions each using different types of imported gas solenoid valve, or it is easy to cause operational errors.

1.2, the material temperature: the material temperature is not the same, the use of matching flame retardant grade products, or easy to be burned through or through, rubber seals easy to embrittlement, endangering the use of years

1.3, viscosity: generally below 20CST, if higher than this value, piston type normally open solenoid valve using pipe diameter beyond 15mm multifunctional solenoid valve, steam solenoid valve manufacturers are not suitable for the use of small diameter solenoid valve.

1.4, when the material cleanliness is not high, the need to install recoil screen in front of the solenoid valve. Working pressure is low when using direct-acting or step-by-step direct-acting pulse damper solenoid valve.

1.5, the substance if the fixed item commodity flow and does not allow backflow, to clearly point out the special provisions.

2、The basic parameters of pipeline

2.1、According to the material inflow and pipeline interface mode, choose the corrosion-resistant normally open solenoid valve gate diameter and specification model.

2.2, according to the user flow and gate valve Kv value to choose the gate valve nominal pressure pipe diameter, but also can choose the same as the inner diameter of the pipeline.

2.3, work on the differential pressure: Z less work on the differential pressure above 0.04MPa using the core type; Z less work on the differential pressure close to or equal to 0 must use the direct-acting or step-by-step direct-acting type.
