  •   Wide range of body-bonnet gasket options like Graphite, Spiral wound SS with Graphite, PTFE and other fillers
  •   Gear, Electric and Pneumatic Cylinder operators can be provided
  • Why fugitive emission is so critical

    In a petroleum plant, 60% of fugitive emission happens from valves. Hence it is critical to reduce the fugitive emission from valves as much as possible.
