Product introduction
Imported zero differential pressure solenoid valve produced by Breer. The driving method can be electromagnetic, the connection method can be flange, thread, structure type can be piston type, pilot type, direct-acting type, and sealing structure can be piston type. Pressure range PN1 .6-100MPa, nominal diameter is DN1-500mm, the material can be selected from cast iron, copper, stainless 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
Buhrer brand-imported zero differential pressure solenoid valve is suitable for automatic control of a variety of media pipelines, especially for non-differential pressure or low pressure systems, such as steam entering sealed pipelines, small differential pressure, or large changes in differential pressure. The valves are adaptable. It can also be used in high-level artesian water tanks, fans, and siphon vacuum systems in water plants.

Imported zero differential pressure solenoid valve is suitable for aerospace, shipbuilding, petrochemical, 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. In the field of low-pressure solenoid valve products. This product is a pilot-operated structure. The valve core is a stainless steel piston. The piston ring will not be stuck by impurities in the medium. It has high dynamic sealing performance and long life. There is no direct friction between the piston and the metal valve cavity. The installation direction of the valve body is unlimited. ; Dedicated coil, not easy to burn; Stop and restart for a long time, the action is also sensitive; Zero leakage; Service life is more than 1.5 million times.

Main technical parameters of imported zero pressure difference solenoid valve:

The working principle of the imported zero pressure difference 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 opens; The pilot valve core is reset by the spring, the pilot hole is closed, the valve cavity 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 hole is closed, the upper cavity of the valve is pressurized by the piston orifice and the thrust of the return spring, 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.
