Anderson Greenwood Safety Selector Valve
A dual PRD system enables safe, efficient switching from active to standby. Maintains overpressure protection.
Key Features
- Provides high Cv values, resulting in less than 3% pressure drop to the active PRV inlet, reducing destructive valve chatter.
- One minimally sized penetration into the vessel or pipe reduces costs.
- Reduces field installation costs and space requirements through preassembled and compact design.
- Provides process isolation of standby PRV.
- Allows PRV maintenance without process shutdown.
- Bleed valve under each PRV vents entrapped process effectively and safely prior to removal for maintenance.
- Clear, positive indication of active PRV.
- Foolproof provisions for dual padlocking in either PRV position.
- Tested packing design and minimal leak points reduce fugitive emissions.
- No seat lapping required for maintenance. Minimal spare parts reduce cost of ownership.
- Simple operation with built-in seat equalization and no special tools minimizes total valve operating time.
- Tandem system available for dual PRV's discharging to a closed header system.
