Product introduction
The imported pilot-operated solenoid valve produced by Breer can be driven by electromagnetic, flanged, threaded by connection, pilot-operated by piston, piston-type by sealed, and pilot-operated by sealed structure, pressure range PN1.6-100MPa, The nominal dia
meter is 1mm-500mmmm, and the material can be WCB, 304, 316, alloy steel, etc. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
Product Details
American
Buhrer brand-imported pilot solenoid valve is widely used in aerospace, marine heavy industry, petrochemical, water supply and drainage, fire fighting equipment, food medical equipment, cleaning equipment, landscape sprinkler irrigation, humidification equipment, hydraulic equipment, testing equipment, water plants, etc. Pressure in the pipeline system of 1.6-100MPa.
Features of imported pilot operated solenoid valve:
Pilot structure, the valve core is stainless steel piston, the piston ring will not be stuck by impurities in the medium, high dynamic sealing performance, long life; no direct friction between the piston and the metal valve cavity, no restriction on the valve body installation direction; special
coil , It is not easy to burn; stop and restart for a long time, the action is also sensitive; the leakage is zero; the service life is more than 1.5 million times.

Working principle of imported pilot solenoid valve:
Normally closed: When the
coil is energized, the pilot valve core is closed, the pilot hole is opened, the upper cavity of the valve is depressurized, the piston is pushed by the pressure of the lower cavity medium, and the solenoid valve is opened.
When the
coil is de-energized, the pilot valve core is reset by the spring, the pilot hole is closed, the upper cavity of the valve is pressurized by the piston throttle hole and the thrust of the return spring is closed, and the solenoid valve is closed.
Normally open: When the
coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, the upper cavity of the valve is pressurized by the piston orifice, and the thrust of the return spring is closed, and the solenoid valve is closed.
When the
coil is de-energized, the pilot valve core is reset by the spring, the pilot hole is opened, the upper cavity of the valve is depressurized, the piston is pushed by the pressure of the lower cavity medium, and the solenoid valve is opened.
Note: The pressure at the outlet end is greater than the pressure at the inlet end, and the medium will conduct back. Non-return valve can be installed
