Globe Valves & Non Return Valves


 Description

  •   Globe Valves and Non Return Valves for Steam / Thermic Fluid, Process and Utility Lines supplied with IBR Test Certificate in Form III C also.
  •   Globe Valves in ASA and DIN Standards.
  •   Non Return Valves in ASA and DIN Standards.

 Features

  •   Suitable for high temperature service.
  •   Low fugitive emission.
  •   Spindles of high quality stainless steel, ground and polished for a very smooth finish for extended gland life.
  •   Gland packing ranging from Graphite, Braided and Reinforced Graphite with SS wires, PTFE, PTFE Chevron, Braided and Reinforced PTFE with SS wires.
  •   Live load on gland packing for extended low fugitive emission service.
  •   Optional stelliting of seats and disc faces for longer life.
  •   Conical disc arrangement for control, PTFE disc insert for gaseous applications.
  •   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.
