CONTROL VALVE
Fisher Control Valve
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.
Features
- 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.
