Electric PTFE-Lined Flanged Ball Valve: The Ultimate Solution for Corrosive Fluid Control
For the most demanding industrial applications involving highly corrosive and aggressive media, a standard ball valve is simply not enough. The Electric PTFE-Lined Flanged Ball Valve is a specialized solution engineered to provide exceptional performance, safety, and longevity in the harshest chemical environments. This advanced ball valve integrates a robust, fully-lined valve body with a reliable electric actuator, offering precise and automated control over challenging fluids. Featuring a full-bore design and a thick, seamless PTFE lining, this ball valve provides a safe and cost-effective alternative to expensive exotic alloy valves, ensuring process purity and operational integrity across a wide range of industries.
Core Advantages & Features
Unparalleled Corrosion Resistance with PTFE Lining
The defining feature of this ball valve is its complete internal lining made from Polytetrafluoroethylene (PTFE). This thick, seamless lining is applied to all wetted surfaces of the valve, including the body and ball, effectively isolating the metal valve components from the process media. PTFE possesses extremely high chemical stability, making this ball valve suitable for nearly any strong corrosive fluid, with the only notable exceptions being “molten alkali metals and elemental fluorine”. This inert barrier prevents both chemical attacks on the valve’s structure and contamination of the process media, making it an ideal choice for high-purity and hazardous chemical applications.
Robust Construction and Zero-Leakage Performance
This ball valve is built for demanding industrial service. The external body is constructed from durable materials like Cast Iron, WCB Carbon Steel, or Stainless Steel, providing structural strength and resistance to external environmental conditions. The valve employs a “full bore and floating ball structure,” which means the opening through the ball is the same size as the pipe, resulting in very low fluid resistance and minimal pressure drop. The floating ball design presses firmly against the PTFE seat to create a tight seal, allowing the valve to be closed “without leakage throughout the entire pressure range”. This bubble-tight shut-off is critical for safety and efficiency in chemical processing.
Reliable and Versatile Electric Actuation
Precise automation is achieved with a high-performance electric actuator designed for reliability and ease of use. The actuator is housed within a rugged, hard aluminum alloy body with a polyester powder coating, providing excellent corrosion resistance and a standard IP65 waterproof rating. Key features include:
Powerful & Stable Drive: A fully enclosed motor delivers high torque, while the accurate turbo-worm gear structure provides a self-locking function to prevent the ball valve from drifting from its set position.
Versatile Control: The actuator is available in a simple ON/OFF type for basic isolation, or an advanced Regulation (modulating) type that accepts input signals like DC 4-20mA or DC 0-10V for precise flow control.
Manual Override: A reliable manual handle is included for emergency operation or for positioning the ball valve during a power outage or system setup.
Engineered for Industrial Service and Easy Maintenance
This flanged ball valve is designed for seamless integration into industrial piping systems, with flange dimensions conforming to international standards for a secure and leak-free connection. The valve features a simple structure that allows for fast opening and closing speeds. The full-bore design also makes it easier for pipeline systems to be cleaned or inspected with pigging tools. The robust stem is made of Stainless Steel 304 or 316 and is sealed with PTFE packing to ensure fugitive emissions are prevented, enhancing plant safety and environmental compliance.
Wide Range of Applications
The superior chemical resistance of this lined ball valve makes it indispensable in industries such as:
Chemical and Petrochemical Processing
Pharmaceuticals and Biotechnology
Pulp and Paper
Industrial Wastewater Treatment
Chlor-Alkali and Fertilizer Production
High-Purity Water Systems
