3/4'' Threaded 2W200-20 Water Solenoid Diaphragm Valve DC12V DC24V

3/4'' Threaded 2W200-20 Water Solenoid Diaphragm Valve DC12V DC24V

The 2W200-20 is a direct-lift valve that combines the function of a direct-acting valve with a pilot-operated valve. Due to the flexible connection between the electromagnet plunger and the diaphragm, the direct valve acts as a direct acting valve at low pressure and acts as a pilot valve at high pressure. It is also known as a zero delta pressure valve or a suspended diaphragm valve. It is applied to commercial dishwashing equipment, car washing equipment, food processing, commercial laundry equipment, washing bottles, disinfection equipment, etc.

Main parts of threaded port electromagnetic water valves:

A solenoid is a cylindrical coil that acts as an electromagnet when current flows through it, and a valve acts as a control device that controls or guides the flow of fluid by closing, opening, or partially blocking various channels.

Body: the main part of a solenoid valve, including the end, seat, and hole, allowing fluid to move when the solenoid is energized or cut off.

Solenoid tube assembly: cylinder, made of stainless steel, sealed and closed at one end. This is the guide channel for the movable plunger, which is magnetically movable. The solenoid coil of the valve is mounted on the outside of the closed tube.

Movable plunger: An electromagnetic induction coil made of removable stainless steel that is attracted by a solenoid magnetic field and slides inside the tube.

Plunger Spring: This is a return spring that holds the movable plunger in place when energized and returns it to its position when the power is off.

Seat seal: Used to close the valve main bore, which is located on the movable plunger.

Electromagnet (solenoid Coil): An electromagnet composed of a copper winding (solenoid) and a yoke (armature) generates a magnetic flux that attracts the movable plunger when energized.

Materials of 2W series solenoid valves:

Body material: neutral fluid body made of brass and bronze. High temperature fluids such as steam and corrosion resistant stainless steel are recommended. In addition, polyimide materials are used in plastic valves for economic reasons.

Seal material: mechanical, thermal and chemical conditions in application are the factors for choosing sealing material. Neutral fluid of standard material at temperatures up to 194 ° F, usually for NBR. For higher temperatures, FKM and PTFE are involved. Selecting the right sealing material for a solenoid valve requires the following considerations.
