Order Control Valve | DIN-ANSI | Corrosion Resistant Flow Control

Precision Control for Corrosive Media

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.
