1. Material Parameters

•Valve Body/Core: 304 Stainless Steel (marked "CF8", resistant to weak acids and alkalis), 316/316L Stainless Steel (marked "CF3M", resistant to strong corrosion and pitting)

•Seals: PTFE (Polytetrafluoroethylene, temperature resistance -20℃~180℃, excellent chemical stability), Metal Hard Seal (Stainless Steel, temperature resistance -40℃~450℃, wear-resistant and particle-resistant)

•Electric Actuator Housing: Cast Aluminum (Lightweight, rust-proof, suitable for humid conditions)

2. Specification Parameters

• Nominal Diameter: DN15~DN300 (corresponding to ANSI 1/2"~12")

• Nominal Pressure: PN16, PN25, PN40 (corresponding to ANSI Class 150, Class 300, Class 600)

• Connection Standards: GB/T (Chinese National Standard), ANSI (American Standard), DIN (German Standard), and other flange standards

3. Control and Protection Parameters

• Control Type: On/Off type (receives DC24V/AC220V switching signals), Regulating type (receives 4-20mA analog signals, precisely adjusts opening)

• Protection Rating: Standard IP65 (dustproof and waterproof), high protection optional IP67/IP68 (can withstand short-term immersion)

• Explosion-proof Rating: Explosion-proof actuator supports Ex d II BT4/Ex d II CT6 (suitable for flammable and explosive environments)

• Operating Temperature: -20℃~180℃ (PTFE seal); -40℃~450℃ (metal hard seal)

•  High degree of automation: Supports remote control and centralized management, eliminating the need for on-site manual operation, suitable for unattended industrial scenarios, reducing labor costs.

• Strong corrosion resistance: The 304/316 stainless steel valve body can withstand various media such as water, oil, weak acids and alkalis, and seawater, resulting in a long service life and low maintenance costs.

• Reliable Sealing and Good Flow: The spherical valve core design ensures a straight flow path when fully open, minimizing fluid resistance. PTFE or metal hard seals meet the sealing requirements of various operating conditions, eliminating leakage risks.

• Convenient Installation and Maintenance: Flange connections are suitable for large-diameter pipelines, facilitating installation and disassembly. Two-piece/three-piece valve body structures are available, simplifying valve core and seal maintenance and replacement.

• Wide Range of Applications: Optional explosion-proof and high-protection-level configurations are available, suitable for conventional water supply and drainage, chemical pipelines, and also for harsh environments such as flammable, explosive, humid, and dusty conditions.

• Petrochemical Industry: Automatic on/off and flow regulation of crude oil, refined oil, and chemical solvent transportation pipelines; explosion-proof models are suitable for flammable and explosive workshops.

• Water Treatment Industry: Control of circulating water, purified water, and sewage pipelines in waterworks and sewage treatment plants, enabling remote automated scheduling.

• Energy and Power Sector: Control of cooling water and steam pipelines (metal hard-seal type) in thermal power plants and nuclear power plants, meeting the requirements of high-temperature and high-pressure operating conditions.

•Food and Pharmaceutical Sector: Piping control for food and beverage processing and pharmaceutical pure water systems; stainless steel material meets sanitary standards, eliminating the risk of media contamination.

• Municipal Engineering Sector: Automatic control of urban heating and gas transmission pipelines, adaptable to large-scale centralized municipal pipeline network systems.
