TESCOM™ Anderson Greenwood Instrumentation H2 Valve Series
These maintenance-free valves feature a positive double-block arrangement that protects workers after they isolate process pressures, while their modular design reduces the number of potential leakage points.
In addition, the maintenance-free hand-operated DBB valves include a non-adjustable seal that avoids the release of high-pressure liquids or gases into the environment while requiring no packing adjustment over the valve’s lifetime.
