1/2"-8" Electric PVDF True Union Ball Valve
This electric PVDF ball valve is an electrically controlled ball valve made of polyvinylidene fluoride (PVDF), belonging to the category of polymer valves. PVDF material possesses excellent corrosion resistance, chemical stability, and high-temperature resistance, with an operating temperature range typically between -40℃ and 140℃.
This valve opens and closes by rotating the ball 90° via an electric actuator. Nominal diameters range from DN15 to DN200 (corresponding to 1/2 inch to 8 inches), making it suitable for conveying corrosive media and for automated control systems in various industries such as chemical, semiconductor, water treatment, pharmaceutical, and environmental protection. The electric actuator enables remote control, automated integration, and precise flow regulation, meeting the demands of modern industry for intelligent control.

Product Features and Benefirs
This Electric Ball Valve Body Material is Polyvinylidene Fluoride, also called PVDF. This valve body material is excellent for chemical corrosion resistance, meanwhile, it is resistant to strong acids (such as HCl, H₂SO₄), strong alkalis, organic solvents, and oxidants; temperature range -20℃ to 140℃; FDA and drinking water standards optional.
Here are some benifits of this valve material:
Less frequent valve replacements: PVDF has a lifespan far exceeding that of ordinary plastic or metal-lined fluoropolymer valves, reducing replacement costs and downtime.
Ensuring Media Purity: No metal ion precipitation, ideal for high-purity applications such as electronic chemicals, pharmaceuticals, and food.
Safe and Reliable: No brittleness or leakage even in high-temperature corrosive environments.
About the electric actuactor, It's standard on/off type or optional 4-20mA intelligent modulating type; IP67 protection rating / explosion-proof type optional; built-in overheat protection, manual override function; compatible with multiple voltages including DC 24V, AC220V, etc. which is safe and easy to maintain.
The electric actuactor can save labor costs, it connects to PLC/DCS systems for remote or fully automated control, eliminating the need for on-site valve operation. Meanwhile, it can control precisely. Regulating valves allow for precise flow control, meeting process requirements such as proportioning, neutralization, and quantitative dosing. What's more, IP67 protection allows installation in humid, dusty, or outdoor environments; explosion-proof models are suitable for flammable and explosive areas.
The full-bore ball design with no flow resistance; self-lubricating PVDF seat with low opening and closing torque, which improves system efficiency, Also, the low pressure loss and reduced pump energy consumption, especially suitable for high-flow pipelines.
Reduced Actuator Sizes: Low torque allows for smaller, more economical electric actuators, saving on procurement costs.
One Valve for Multiple Scenarios: From small-diameter dosing lines to 8-inch main pipelines, unified brand spare parts facilitate management.

Sealing and Connection Methods
Standard PTFE seat/seal; Connection methods include flange, butt weld, socket weld, threaded (small diameter), etc.; EPDM or FKM sealing materials are optional.
Zero Leakage: Double-seal structure + precision-machined spherical surface, passing ISO 5208 Rate Class A leakage test.
Out-of-the-Box: Provides connection methods that are fully compatible with existing piping systems, requiring no pipe modifications.
Application Case : Automatic Dosing System for Acidic Media in a Chemical Plant
A customer was using a stainless steel ball valve, which was corroded and perforated by hydrochloric acid within a month, requiring weekly replacement. After switching to this electric PVDF ball valve, it has been running continuously for 18 months without leakage, and can be remotely switched on and off from the central control room, eliminating the need for workers to wear protective clothing and operate on-site."Applicable operating conditions: hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, sodium hypochlorite, etc.
