OSA70 series corrosion-resistant solenoid valve (PTFE)

Scope of application

Applied to highly corrosive fluid media such as strong acids, strong bases, strong oxidants, and organic solvents, as well as ultra pure fluids. For example, hydrochloric acid, concentrated sulfuric acid, various electroplating solutions, aromatic solventsAutomatic control of high-purity fluid and other pipelines. Widely used in various corrosive media, it is the best matching product for automated fluid control.

Characteristics of anti-corrosion polytetrafluoroethylene (Plastic King) solenoid valve

1. Working principle of anti-corrosion PTFE solenoid valve:

a. The coil is energized, the moving iron core is attracted, the valve stem assembly moves upward, the secondary valve port (valve core hole) opens, the fluid is released from the secondary valve port (valve core hole), and the valve core is subjected to the action of the fluidForce opens the main valve port, fluid flows out from the main valve port, and the solenoid valve opens and works normally.

b. The coil is powered off, the moving iron core is reset by the spring force, the valve stem assembly moves downward, the auxiliary valve port (valve core hole) is closed, and the valve core is closed by the fluid and spring force, closing the main valve port,The solenoid valve is closed.

2. Unique structural technology:

a. Pilot piston or direct acting structure, quick opening and closing, unique soft sealing technology, no dripping or leakage.

b.The sealing element adopts imported high-tech products with strong corrosion resistance and can withstand various strong acids（98% concentrated sulfuric acid, strong alkali, strong oxidant, and organic solvent,Can be used for a long time without damage.

c. Isolate the fluid medium from other metal components.

3. Superior chemical stability:

a.Suitable for strong acids（Strong corrosive fluid media such as 98% concentrated sulfuric acid, aqua regia, strong alkali, strong oxidant, and organic solvents.

b. Excellent resistance to atmospheric aging, anti-oxidation, anti surface fouling, anti fading, and anti-oxidation properties.

c. Non polluting, non-toxic, odorless, with high purity and chemical inertness, it will not have any impact on the fluid medium, suitable for ultra pure fluids, water treatment, medical water treatment, etc.

4.Wide range of temperature usage:It can be-Long term use within the temperature range of 50 ℃ to+200 ℃.
