Flow and Control Engineering Supplying Control Valves & Instrumentation to Heavy Industry and Chemical Manufacturing. Multi-Stage Steam & Condensate Control Valves Slide Blind Valves Metal Bellow Sealed Valves Manual & Automated Ball Valves Butterfly & Knife Gate Valves Industrial Heat Exchangers Industrial Vent Silencers Opacity Monitoring EPA Series 60 Compliant

Line Blanking or Blinding Stop a process flow by placing an obstruction in the line. Prevents release of combustible and toxic materials, vapors or gasses into the work area. When do we Blank or Blind? Confined Space or Vessel Entry Process Control Commissioning or Startup Maintenance Repairs Welding Extended Shutdown

Parts and Warranty Standard Maintenance is gasket replacement. All gaskets can be replaced at site Replacement period of seal ring can be different by gasket kind and working conditions

Safety Features Part Description Double Lock System Handle is secured by SS chain and locked in double so it’s safe even by extreme vibration Optional Double Sealing When first O-ring is damaged, second O-ring keep safe (prevent leakage) and as standard dimension it can be easily purchased anywhere in the world

Options Bleeder connection Automation This bleeder is able to drain out fluid remaining in the line before operation Automation Remote control is available with automated operation like other conventional control valves.
