GFT 9 PFA Transfer Molding Meets Precision Engineering

PFA Lined Control Valve

Imperium9
The Imperium9 PFA-Lined Globe Control Valve is engineered for high-precision flow control in aggressive chemical environments. Its virgin PFA lining (5-6 mm thick) provides superior corrosion resistance, while its vacuum-proof anchoring ensures a leak-free, long-lasting performance. Equipped with a powerful pneumatic actuator and a multi-functional digital positioner (supporting HART, Profibus, and Fieldbus communication), the Imperium9 enables seamless integration into automated process control systems. The TA-Luft compliant stem seal, removable bonnet, and high-precision trims allow for easy maintenance and extended durability. Its interchangeable seat and plug system ensures adjustable kv-values for precise control, while specialized V-plugs and U-plugs are designed to handle small flow rates, cavitation risks, and high-pressure differentials. Additionally, its standard and heavy-duty PFA bellows options provide enhanced safety and contamination prevention for industries handling pure, permeating, or highly reactive media. Built to handle extreme pressures, temperatures, and chemically aggressive conditions, the Imperium9 is the go-to solution for demanding flow control applications.

Feature Image 5

Powerful Valve Actuator


The valve is equipped with a pneumatic multi-spring actuator for rapid operation, constant seating force, and cost efficiency. Electric actuators are available as an option.

Multi-Functional Digital Positioner


The digital positioner is a versatile interface for process control, operating with 4 to 20 mA signals and supporting HART, Profibus (PA), and Foundation Fieldbus (FF) communication. It enables bidirectional data exchange and can be configured on-site or remotely.

Reliable Stem Seal


The stem seal is TA-Luft (Clean Air Act) compliant, offering a tight seal that prevents emissions and withstands corrosion.

Removable Bonnet (Top Entry)


The bonnet allows for easy access to internal components, facilitating maintenance and minimizing downtime.

Robust, High-Precision Trims


The valve is equipped with replaceable seats and plugs made from TFM-PTFE, ensuring durability and easy serviceability. Special valve trims such as V-plugs and U-plugs can handle small kv-values and high-pressure differentials.

Customizable Bellows


The PFA bellows (standard or heavy-duty) protect against leakage and corrosion, available for a wide range of media and operating conditions (see below for detailed analysis).

Interchangeable Plug and Seat


The TFM-PTFE seat and plug can be swapped to adjust kv-values, offering high precision in control, even under extreme conditions (see below for detailed analysis).

Safety Features


Equipped with safety packing, stroke limitation, and monitoring connections, the valve is designed for high-pressure and high-temperature applications
