Fully Welded Valve
Series 8200 FW Fully welded ball valves are suitable for use in pipe lines for transportation of gases, underground installations, oil & gas industry, offshore platforms, sub sea installations & onshore platforms.
The complete forged body ensures soundness without any concerns for defect is like porosity sand inclusion & shrinkage defects which are generally associated with cast valve bodies . & Fully welded construction avoids bolted joints & risk of leakages & fugitive emission from valve body.
Valves are manufactured with Quality Programme in accordance with ISO 9001:2000 and also have accreditation for European Directive 97/23/EC (PED).
Third Party Inspections at manufacturing & final stage can be offered to Agencies like Bureau Veritas, TUV RINA, Lloyd's Register & DNVetc.
