Double sealing titanium stopper valve is a special valve with excellent corrosion resistance and high sealing reliability. It is widely used in corrosive environment, high sealing requirements and complicated operating conditions. Because of their titanium construction and double sealing structure, they offer significant advantages in the situation of traditional stainless steel valves which are difficult to operate stably for a long time.
1.Highly Corrosive Media Conditions
Titanium is highly corrosion resistance, especially in oxidizing media and chlorine-containing environment. Therefore, dual-seal titanium plug valves are most suitable for:
Chemical media such as hydrochloric acid and hydrochloric acid (appropriate grades must be selected according to concentration and temperature)
Chronic acid solution
Sodium hypochlorite solutions
Seawater and high-salinity wastewater
Wet chlorine systems
Bleach delivery systems
In this environment, ordinary carbon steel or stainless steel valves are prone to spot corrosion, crevice corrosion and stress corrosion cracking, while titanium valves have a longer service life.
2.Marine Engineering and Seawater Treatment Conditions
Marine environment contains a large amount of chloride ions, which seriously corrodes metal equipment. Dual-seal titanium plug valves are commonly used for:
Seawater desalination plants
Offshore oil platforms
Ships' ballast water systems
Shipboard cooling circulation systems
Marine chemical equipment
Double seal design effectively prevents media leakage and improves system safety.
3. High seal requirements
For production systems where media leakage is unacceptable, double sealing structures provide double protection for:
Transport of toxic agents
Storage and transport of volatile chemicals
High-value chemical feedstock transport
Environmental emission control systems
After the main seal wear, the auxiliary seal can still maintain a good sealing effect, thus reducing the risk of leakage.
4. Petrochemical industry
Petrochemical production processes involves a large amount of corrosive media and complex operating conditions. Dual-seal titanium plug valves are commonly used for:
Chlor-alkali plants
PTA Production Plant
Fertilizer production systems
Fine chemical production line;
Acid-base alkali storage tanks and pipeline systems
Its fast opening and closing speed, low flow resistance, convenient maintenance, meet the requirements of continuous production.
5. Pharmaceutical and food industries
Titanium has good biocompatibility and anti-fouling properties in applications that require high media purity. It is suitable for:
Pharmaceutical process piping
Transportation of high-purity chemicals
Fermentation equipment systems
Purified water systems
Special food processing equipment
The dual-seal structure helps prevent external pollutants from entering the system.
6. High temperature and medium pressure conditions
According to sealing material and structural design, double seal titanium plug valves can also be used for:
Medium and high pressure chemical pipelines
Heat exchangers
High-temperature corrosive media transport;
Industrial steam auxiliary systems
In practice, valves should be selected according to their rated pressure and temperature range.
