Does material selection affect pneumatic actuator ball valve durability

Pneumatic Ball Valve Material Selection

Engineering solutions for extended service life

1Body & Ball Materials

316 SS Duplex WC-Coated

Tungsten carbide-coated balls reduce abrasion wear by 70% in slurry applications

2Seat Materials

PTFE Inconel PEEK

PTFE seats offer chemical resistance but limited to ≤260°C, while metal seats withstand 650°C

3Actuator Components

Anodized Al Stainless

Anodized aluminum resists humidity while cast iron increases friction due to rust

4Lubricants & Seals

FDA Grade Synthetic

Food-grade silicone grease prevents contamination in pharmaceutical applications

Material Performance

Optimized materials (e.g., Hastelloy C for H₂SO₄) enable 10+ years service vs months for incorrect choices
