Lubricated Plug Valves - Twin Isolation

• Improved plant and personnel safety assured by a double isolation design that allows the operator to verify valve isolation before carrying out maintenance
• A cost-, space- and weight-saving alternative to a double block and bleed system using two valves in a series
• Ease of installation from a compact design with the same face-to-face dimension as a single valve, often replacing it without the need for pipe work modifications
• Greater process control via pressure balanced design that provides a true bubble-tight double isolation capability within a single valve body
