What Is a Water Solenoid?

This valve is a pilot-operated solenoid valve with double opening. Its structure mainly consists of a pilot valve and a main valve.

Water solenoid valve

Right!
This valve is a pilot-operated solenoid valve with double opening. Its structure is mainly composed of a pilot valve and a main valve. The main valve adopts a rubber seal structure.
The selection of solenoid valve should first follow the four principles of safety, reliability, applicability, and economy, and then follow the six site conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, operating methods, Special requirements to choose).
First, select the solenoid valve according to the pipeline parameters: diameter specifications (that is, DN), interface method
1. Determine the size of the diameter (DN) according to the on-site pipe diameter or flow requirements.
2. Interface mode, generally> DN50 should choose flange interface, DN50 can choose freely according to user needs.
Second, select the solenoid valve according to fluid parameters: material, temperature group
1. Corrosive fluid: Corrosion-resistant solenoid valve and all stainless steel should be selected; Super clean fluid: Food-grade stainless steel solenoid valve should be selected.
2. High temperature fluid: select solenoid valves made of high temperature resistant electrical materials and sealing materials, and choose piston type.
3, fluid state: large gaseous, liquid or mixed state, especially when the caliber is larger than DN25 must be distinguished when ordering.
4, fluid viscosity: usually below 50cSt can be arbitrarily selected, if it exceeds this value, a high viscosity solenoid valve should be used.
This valve is a pilot-operated solenoid valve with double opening. Its structure is mainly composed of a pilot valve and a main valve. The main valve adopts a rubber seal structure. In the normal position, the movable iron core seals the pilot valve port, the pressure in the valve cavity is balanced, and the main valve port is closed. When the coil is energized, electromagnetic force is generated to attract the movable iron core, and the medium in the main valve cavity leaks from the pilot valve port, so that a pressure difference is generated, the diaphragm or valve cup is quickly lifted, the main valve port is opened, and the valve is Access. When the coil is de-energized, the magnetic field disappears, the movable iron core is reset, the pilot valve port is closed, and after the pressure in the pilot valve and the main valve cavity is balanced, the valve is closed again.
