Buhrer brand - Imported zero pressure differential solenoid valveSuitable for automatic control of various media pipelines, especially for systems with no pressure difference or low pressure, such as steam entering sealed pipelines, with small pressure difference or large changes in pressure difference size, this valve can adapt to all situations. It can also be used for high-level self flowing water tanks, fans, siphon vacuum systems in water plants, etc.

Imported zero pressure differential solenoid valveSuitable for various fields such as aerospace, shipbuilding, petrochemicals, industrial furnaces, boilers, water supply and drainage, heating and air conditioning, fire-fighting equipment, drying equipment, food and medical equipment, cleaning equipment, landscape sprinkler irrigation, water plants and other pipelines. This product has a pilot operated structure, with stainless steel pistons for the valve core. The piston ring will not be stuck by impurities in the medium, and it has high dynamic sealing performance and long service life; There is no direct friction between the piston and the metal valve chamber, and there is no restriction on the installation direction of the valve body; Autocratic coil, not easy to burn out; Long term stop action restarts, with equally sensitive action; Zero leakage; The service life is over 1.5 million times.

Imported zero pressure differential solenoid valveWorking principle: Normally closed: When the coil is energized, the pilot valve core is attracted, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve is opened; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the valve chamber is pressurized by the piston throttle hole and the thrust of the reset spring, and the solenoid valve is closed. Normally open: When the coil is energized, the pilot hole closes, and the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, causing the solenoid valve to close. When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve opens.
