Product Description

Key Features

1. Dual Fluoropolymer Defense

PTFE Seat: Resists 98% sulfuric/nitric acids and halogen gases (-20°C to 200°C).

PFA-Coated 316L SS Disc: 500µm thick coating prevents pitting/corrosion under ASTM G48 testing, with Ra≤0.4µm surface smoothness for particle-free flow.

2. Zero Contamination Guarantee

Full fluoropolymer barrier isolates media from metallic components.

3. High-Temperature & Abrasion Resilience

PFA coating withstands 260°C intermittent peaks.

30% higher abrasion resistance than uncoated discs in slurry services.

4. Bubble-Tight Sealing

PTFE-to-PFA contact achieves ISO 5208 Rate A shutoff at 1.5x PN16 pressure.

Fire-safe option: API 607 metal secondary seals.

5. Maintenance-Optimized Design

Wafer-style body with ISO 5211 pad enables 10-minute actuator swaps.

Self-aligning disc prevents galling after 20,000+ cycles (ISO 9001 validated).
