Compressor Valves

ACI offers a complete line of proprietary designed compressor valves. Valve type and internals are selected to provide optimized service and performance under varied operating conditions. Compressor valving is a science in itself and requires more detail than the below general outline provides. For detailed valve analysis, please contact ACI Services, Inc.

Plate Valves

• Offered in damped, individual ring, and ported plate designs.
• Damped plate valve employed in high pressure applications or where liquids and/or dirt are present, and endurance is the primary concern. Process applications are typical.
• Ported plate valves offer a good selection for balance of efficiency and endurance. Gas gathering and storage service are areas of common applications.

Accu-Guide™ Poppet Valve

• Patented design concept that overcomes mechanical failure problems associated with many conventional poppets. Used in gas transmission, storage and process services where additional fixed clearance can be tolerated.

Valve Styles - Poppet and Plate

• Single Deck: Used in cylinders with acceptable valve area to swept volume ratio -- minimal fixed clearance compared to other valve styles
• Double Deck Opposed Flow: Utilized with valve cap unloaders or where additional free lift area, compared to single deck valves, is required. Fits into reasonable valve pocket depths.
• Double Deck Parallel Flow: Same lift area as opposed flow valves, but higher fixed clearance. Requires generous valve pocket depths. More efficient gas flow than opposed flow valves.
• Deck and One Half Parallel Flow: Greater plate lift area than other double decks and less fixed clearance than most multi-deck valves. Not usable with valve cap unloading equipment. Requires generous valve pocket depth.

Valve Styles - Replications

• Complete replacement valves for Cooper C5V single deck and C6V double deck valve series.
