• Sealing Surface: Stainless steel hard alloy overlay (wear-resistant and high-pressure resistant), PTFE soft seal (zero leakage at low pressure)

• Valve Stem: 2Cr13 stainless steel, 304 stainless steel (corrosion-resistant, anti-locking)

• Electric Actuator: Cast aluminum housing (lightweight and rust-proof), optional stainless steel housing (for highly corrosive environments)

2. Specification Parameters

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

Nominal Pressure: PN16, PN25, PN40, PN63 (suitable for medium and high-pressure pipeline systems)

Connection Method: Flange connection (GB/T, ANSI, DIN standards), threaded connection (small diameter)

3. Control and Operating Parameters

• Actuator Type: Switch type (receives DC24V/AC220V switching signals for full open/close), Regulating type (receives 4-20mA analog signals for precise valve opening adjustment)

• Protection Rating: Actuator IP65 (standard dust and water protection), optional IP67/IP68 (high protection, suitable for humid immersion environments)

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

• Operating Temperature: -29℃~425℃ (WCB material); -29℃~595℃ (WC6/WC9 material); -20℃~180℃ (PTFE soft seal)

• Sealing Rating: GB/T 13927-2008 Class IV (hard seal); VI Grade 1 (Soft Seal, Zero Leakage)

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

• Reliable sealing performance: The hard-seal version is wear-resistant and high-pressure resistant, suitable for long-term high-temperature and high-pressure working conditions; the soft-seal version can achieve zero leakage, meeting the requirements of scenarios with stringent sealing requirements.

• Precise and flexible control: The positioning accuracy of the adjustable actuator can reach ±1%, and with the linear flow characteristics, it can stably control fluid parameters and avoid fluctuations in pipeline pressure and flow.

• Wide range of working conditions: A variety of materials and protective configurations are available, which can be used for conventional water supply and drainage, HVAC pipelines, as well as complex working conditions such as chemical, petroleum, corrosive, flammable and explosive, high temperature and high pressure.

• Easy installation and maintenance: Flange/threaded connection methods are suitable for different pipeline requirements and the installation is stable; the actuator and valve body are easy to disassemble and separate, and the only vulnerable parts are the sealing surface and packing, resulting in low replacement costs.

• Petrochemical Industry: Pipelines for conveying crude oil, refined oil, and chemical solvents; explosion-proof type suitable for fluid cutoff and flow regulation in flammable and explosive workshops. 

• In the power energy sector: for boiler feedwater and steam pipelines in thermal power plants, the chromium-molybdenum steel version can withstand high temperature and high pressure conditions, ensuring stable system operation.

• Pharmaceutical and food industries: Pharmaceutical pure water systems and food and beverage processing pipelines; stainless steel models meet hygiene standards and pose no risk of media contamination.

• In the field of HVAC: For central air conditioning chilled and hot water pipes, regulating actuators can precisely control the flow rate, achieve constant temperature and pressure control in buildings, and reduce energy consumption.

• Municipal engineering field: urban gas and high-pressure water supply and drainage networks, used for network zone control and maintenance isolation, to improve network operation safety.
