Performance of solenoid valve (1)

safety:

1. Corrosive medium: Plastic solenoid valve and all stainless steel should be used; for the strong corrosive medium, the level gauge must use the isolation diaphragm type.

Example CD-F. Z3CF.

For neutral media, a solenoid valve with copper alloy as the material of the valve housing should also be used, otherwise, rust debris in the valve housing will often fall off, especially when the action is not frequent. The valve for ammonia cannot be made of copper.

2. Explosive environment: products of corresponding explosion-proof grade must be selected, and waterproof and dust-proof products should be selected for outdoor installation or dusty places. 3. The nominal pressure of the solenoid valve should exceed the high working pressure in the pipe.

reliability:

1. Working life, this item is not included in the factory test item, it belongs to the type test item. To ensure quality, products from regular manufacturers should be selected.

2. Work system: divided into long-term work system, repeated short-time work system and short-time work system. The company's conventional products are long-term work, that is, the coil allows long-term energized work. If the valve is open for a long time and only closed for a short time, normally open solenoid valve should be used. Stainless steel solenoid valve is used in short-time working system and the batch is large, and special order can be made to reduce power consumption.

3. Operating frequency: When the operating frequency is high, the structure should be a direct-acting solenoid valve, and the power supply should be preferably AC.

4. Action reliability Strictly speaking, this test has not been formally included in the professional standards of solenoid valves in my country. To ensure quality, products from regular manufacturers should be selected. In some occasions, the number of actions is not many, but the reliability requirements are high, such as fire protection, emergency protection, etc., must not be taken lightly. Especially important, two insurances should be used in conjunction.
