Are Acid and Alkali Butterfly Valves the Best Choice for Chemical Plants?

Chemical plants face a brutal truth: ordinary valves just don’t last long when exposed to strong acids or bases.
This is where acid and alkali butterfly valves come into play.

If you’ve ever searched online for:

• “Corrosion resistant butterfly valve supplier”

• “Acid handling butterfly valve China manufacturer”

• “Alkali resistant valve for chemical plant”
  …then this article is exactly for you.

1. The Corrosion Problem

Pipelines carrying sulfuric acid, hydrochloric acid, sodium hydroxide, or ammonia can quickly corrode standard valve bodies and seats.
Without proper material selection, failure is inevitable—sometimes in just months.

2. What Makes Acid/Alkali Butterfly Valves Different?

At Shanghai Rogers Valve, we design valves with:

• PTFE or rubber lining for corrosion protection

• Stainless steel or duplex stainless steel bodies

• Triple eccentric design for zero leakage shutoff

• Custom coatings for harsh acid/alkali environments

One customer joked, “These valves are tougher than our plant’s floor tiles.” Not totally scientific, but you get the point.

3. Applications Across the U.S. Market

• Chemical production plants

• Pulp & paper mills

• Water treatment facilities (chlorine dosing systems)

• Mining & metallurgical processes

• Pharmaceutical plants

These valves help American buyers reduce maintenance downtime, which is often the hidden cost of inferior valves.

4. Installation & Maintenance Tips

• Always check compatibility charts before choosing valve material.

• Don’t overtighten flange bolts (this is a common mistake).

• Plan for periodic inspection of lining integrity.

And remember—choosing the wrong valve can cost more than just replacement money, it can cause safety risks.
