Characteristics of solenoid valves for refrigeration
Applicability
The fluid in the pipeline must be consistent with the medium calibrated in the series of solenoid valves selected.
The temperature of the fluid must be smaller than the calibration temperature of the solenoid valve.
Solenoid valve allows liquid viscosity generally below 20CST, greater than 20CST should be noted.
When the working pressure difference is less than 0.04 MPa, direct and step-by-step operation such as ZS, W, ZQDF, ZCM series should be selected; when the minimum working pressure difference is greater than 0.04 MPa, pilot type (differential pressure) solenoid valve can be selected; the maximum working pressure difference should be less than the maximum calibration pressure of solenoid valve; generally solenoid valves work in one direction, therefore. Pay attention to whether there is a reverse pressure difference, if there is a check valve installed.
1. sets of direct acting open valve and pilot valve opening two in one special structure.
2. zero pressure can also open the main valve, with low flow rate and wide application range.
3. different use of media, the use of targeted seal, improve the rationality of solenoid valves;
4. the valve plug adopts a single molding process to improve the life and reliability of the solenoid valve.
5. adopt investment casting copper body, the appearance is exquisite and beautiful.
Structural characteristics of solenoid valves for refrigeration
Electromagnetic step by step direct piston type operation structure
1. A two in one special structure with direct acting open valve and first open valve.
No pressure can also open the main valve, low pressure differential flow rate, wide range of applications.
(3) sealing with PTFE and good temperature resistance.
4. Zero pressure difference can act reliably.
Type: normally closed.
