Fisher Dirty Service Trim
Fisher Dirty Service Trim is designed for dirty, cavitating services. This trim utilizes a series of flow restrictions and expansions to eliminate cavitation, while allowing up to 19 mm (3/4 in) diameter particulate to pass through without plugging. Each of the trim stages has a successively larger flow area.
Features
- Designed to prevent cavitation.
- Can pass up to 19 mm (3/4 in) diameter particulate.
- The protected seat design separates the shutoff function from the throttling function to protect the seating surfaces from throttling wear.
