DURCO G4 NON-LUBRICATED PLUG VALVES
The Durco G4 non-lubricated plug valves are designed for highly corrosive and challenging chemical services where drop‑tight shutoff is critical. Their robust engineering delivers long‑lasting reliability and ensures seamless performance across a range of industries. Thus, making them ideal for basic and specialty chemicals, petrochemicals, and downstream processing.
Features and Benefits
- Reliable, Tight Shutoff: The Durco G4 delivers a dependable seal every time. Its precision‑fitted plug and PTFE sleeve design create a highly effective primary seal. Therefore, making it ideal for critical services where absolute shutoff is required.
- In‑Line Seal Adjustment: The tapered plug design allows in‑line seal adjustments within seconds. Its dual adjuster fasteners reduce maintenance times and help minimize costly downtime.
- Low Fugitive Emissions: The fluoropolymer reverse‑lip diaphragm provides a pressure‑activated, self‑energizing stem seal. This design drastically reduces fugitive emissions, hence ensures long‑term compliance with environmental standards.
- Actuator Compatibility: The Durco G4 works seamlessly with a range of Automax actuators and other process controls. This versatility allows easy integration into automated flow control applications.
- Designed for Challenging Services: The Durco G4 accommodates lethal, toxic, and sub‑zero fluid services. Moreover, its robust design and precision engineering make it ideal for harsh environments and critical flow control.
