Fisher™ CAV4 Valve

Fisher CAV4 valves are designed for clean; cavitating services where the pressure drop is above 207 bar (3000 psi). The Cavitrol™ IV trim in this valve is designed to have an expanding flow area. Each of the trim stages has a successively larger flow area. The result is a very efficient operation because more than 90 percent of the overall pressure drop is taken in the initial stages; where there is little danger of cavity formation which could result in cavitation.

• Designed to prevent cavitation.
• Has a pressure drop limit of 552 bar (8000 psi).
• The protected seat design separates the shutoff function from the throttling function to protect seating surfaces from throttling wear.
• Hardened trim materials provide excellent wear resistance; resulting in long trim life.
• Soft metal-to-metal seat provides tight shutoff without the need for periodic lapping.
• Cage-type trim allows removal and inspection of parts without taking the valve body out of the pipeline.
