DN600 PEEK Seat Insert: Reliable Sealing for Demanding Industrial Valves
Engineered for large-diameter valve systems, the DN600 PEEK Seat Insert leverages the superior properties of ARKPEEK-1000® to provide a long-lasting, maintenance-free sealing solution. Unlike metal or elastomer seats, this insert combines PEEK’s intrinsic resilience with precision machining to ensure leak-free performance in the harshest environments.

Why Choose the DN600 PEEK Seat Insert?

ARKPEEK-1000® Advantages:

Chemical Resistance: Withstands acids, hydrocarbons, steam, and sour gas, eliminating corrosion-induced failures.

Thermal Stability: Operates continuously at 260°C (500°F) with short-term tolerance up to 310°C.

Low Friction & Wear: Reduces valve stem wear and extends service intervals.

Large-Diameter Precision:

DN600 (600mm nominal diameter) design ensures compatibility with industrial-scale valves.

Tight tolerances (±0.05mm) for seamless integration into gate, ball, or butterfly valves.

Certified Quality: ISO 9001 manufacturing, FDA compliance (for water/food contact), and RoHS/REACH compliance.

Industry Applications

Oil & Gas: Replace corroded metal seats in pipeline isolation valves, wellhead controls, and refinery systems.

Chemical Processing: Resistant to sulfuric acid, chlorine, and solvents in reactor feed valves.

Water Treatment: Non-toxic, biofilm-resistant seats for potable water and wastewater systems.

Power Generation: Reliable sealing in high-pressure steam valves and geothermal energy plants.
