PTFE solenoid valve is a solenoid valve made of PTFE Body. The PTFE solenoid valve has excellent corrosion resistance property. The PTFE solenoid valve is applicable to most acid, alkali, salt solutions and organic solvents. 

Material characteristics of PTFE solenoid valve

a) Material of valve body, bonnet, valve core and valve rod are made by PTFE

b) Seals: high tech seals, with strong corrosion resistance, can withstand various strong acids (98% concentrated sulfuric acid), strong alkalis, strong oxidants and organic solvents, and can be used for a long time without damage

Unique structure and technology of PTFE solenoid valve

a) Corrosive fluid is completely isolated from metal parts (moving iron core and spring), that is, the fluid is only in contact with polytetrafluoroethylene and seals.

b) The piston structure replaces the diaphragm to avoid the rupture and expansion failure of the diaphragm due to the action of corrosive fluid, which greatly increases the service life of the solenoid valve;

c) The pilot hole has a large diameter, short and straight path, and is not easy to be blocked by particles, sediments or crystals in the fluid (for example, sediment in water, crystalline salt in brine, etc.)

d) The embedded sealing structure makes the sealing performance more reliable and realizes zero leakage of the solenoid valve.

Advantages of polytetrafluoroethylene (PTFE) solenoid valve

a) It is applied to various corrosive fluids to achieve zero leakage.

b) The flow hole diameter of the solenoid valve is the standard value, meeting the corresponding flow requirements.

c) Wide pressure range: zero pressure direct acting type; Pilot operated nominal pressure 0.6MPa; Or 1.6Mpa

d) It is widely used in strongly corrosive fluid media such as strong acid, strong alkali, strong oxidant and organic solvent, as well as ultra pure fluid. For example, automatic control of hydrochloric acid, concentrated sulfuric acid, various electroplating solutions, aromatic solvents, aliphatic solvents, high-purity fluids and other pipelines; And it has strong adaptability to particles, precipitates and crystals in the fluid.
