AVCO Valve
Ball valves, knife gate valves, high-performance butterfly valves, and a dedicated Chlorine Service Ball Valve — forged/cast, engineered in the USA.
AVCO Valve makes forged and cast ball valves, knife gate valves, high-performance butterfly valves, and actuation. Its Chlorine Service Ball Valve complies with Chlorine Institute Pamphlet 6, Classes I and IV, with Monel 400 or Hastelloy C trim. HP1100 ball valves reach Class 2500 or 6000 WOG, and 6100 Series knife gates use a bevel edge for slurries.

Frequently Asked Questions
Does AVCO make a valve specifically for chlorine service?
Yes — the AVCO Chlorine Service Ball Valve complies with Chlorine Institute Pamphlet 6 for Service Classes I & IV, with a carbon steel body, Monel 400 or Hastelloy C wetted trim, and a vented ball for pressure relief during operation.
What is the highest pressure rating among AVCO ball valves?
The HP1100 Series is rated up to ANSI Class 2500 or 6000 WOG — the highest pressure rating of any AVCO ball valve, using SAE AS5202 aerospace-standard fitting ends and Delrin or PEEK seats.
What makes the AVCO 6100 Series knife gate valve suited to slurry service?
The gates are polished and lapped on both sides with a machined bevel on the bottom edge specifically designed to cut through solids and provide a tighter seal when closed — a real, distinct mechanical approach for solids-laden or slurry media.
