Threaded plug-in pressure regulating valve YF04-01

I. Natural environmental standards

1. The high and low ambient temperatures of the natural environment should be within the allowable range. If there is any deviation, it needs to be clearly put forward.

2. In places with high air humidity and water dripping in the rain in the natural environment, damp-proof solenoid valves should be adopted.

3. There are often vibrations, bumps and impacts in the natural environment, and unique types should be taken, such as ship solenoid valves.

4, in corrosive or flammable and explosive natural environment, the application should first choose corrosion resistance according to safety regulations.

5. If the indoor space in the natural environment is limited, please choose a multi-purpose solenoid valve, because it saves the bypass and three manual valves and is convenient for online maintenance.

Ⅱ.Second, the switching power supply standard

1. The manufacturer of two-way cartridge valve selects communication AC and DC solenoid valves according to the power type of distribution switch. Generally speaking, it is convenient to get alternating current.

2. AC220V.DC24V is the first choice for working voltage specifications.

3. Power supply voltage fluctuation usually adopts +%10%.-15% for communication and communication, and DC allows+/-10. If there is deviation, voltage regulator measures shall be adopted or unique ordering regulations shall be clearly put forward.

4. The rated voltage and output power consumption should be selected according to the switching power supply volume. When starting communication, attention must be paid to the high VA value, and indirect conductive solenoid valve should be preferred when the volume is insufficient.

Ⅲ.Third, the accuracy

1. Generally speaking, the plug-in relief valve can only open and close two parts. When the accuracy is high and the main parameters are stable, please select multiple solenoid valves; Z3CF three-position switch solenoid valve, with total flow of micro-start, full start and close; The multi-purpose solenoid valve has four total flows: full open, excellent, small moon and full open.

2. Stability time: refers to the time taken for the electronic signal to be connected or disconnected to the distribution valve posture. The technical multi-purpose solenoid valve can adjust the opening and closing time separately, which not only can achieve the precision requirements, but also can avoid water hammer damage.
