Overview Details for DTS-G
Fisher™ DST-G Trim
Fisher DST-G trim is specially designed for clean or dirty services where the fluid has dissolved gases that are released from a solution due to a reduction in pressure (outgassing). Outgassing typically causes two types of damage: cavitation and erosion by the fluid stream. DST-G trim stages the pressure drop; similar to the DST trim; to prevent cavitation. Erosion is controlled by the lower cage in this trim; which separates the flow stream into smaller; lower energy jets that are less likely to cause damage. This trim also has the ability to pass particulate up to 6.35 mm (1/4 in) in diameter.
- Designed to control outgassing.
- Has a pressure limit of 175 bar (2500 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.
- Cage-type trim allows removal and inspection of parts without taking the valve body out of the pipeline.
- The cage utilizes large slots to separate flow into smaller jets that are less prone to erode the valve body and generate vibration.
