Durco Plug Valve
Durco Non-Lubricated Plug Valves – Mach 1
Durco Non-Lubricated Plug Valves – Mach 1 is available in a Class 600 (derated) version. This provides more opportunities to satisfy customer and process requirements. The Mach 1 is a non-lubricated (sleeved) quarter turn plug valve capable of in-line service and repair. The Mach 1 Marathon is designed for reliable performance in high cycle on-off or modulating services. Fugitive emission containment is often equal to more expensive severe or toxic service valves.
Features
- Replaceable seat
- Lower operating torques
- Higher temperature capability
