Closure Devices

The 585 series offers three external closure adjustment devices:

  • Lever and Spring

These options are used to control closing dynamics in pump stations and networks where slam or transient pressures are a concern.

Maintenance and Access

The valve body features a full-flow area and a top access cover. The stainless steel body seat is field-replaceable without removing the valve from the line. Disc seat replacement requires depressurization and valve removal as per the manual.

Installation

The valve can be installed in horizontal pipelines or vertical lines with upward flow. The counterweight arm must be set horizontally. Prior to installation, piping should be cleaned of welding debris, oils, greases, and foreign matter.

FAQ
