  • STANDARD PRODUCTION SPECIFICATION
  • BODY
  • Body is made in cast and designed according to HLC’s design program and relevant specifi cations. For cryogenic service, it’s made in cast of Austenitic Stainless Steel to have higher impact strength, minimum heat loss and protection against corrosion.
  • SEAT SURFACE
  • Basically, HLC is supplying seal welded seat ring type with Stellite 6 overlay. but it’s possible with integral seat overlaid Stellite 6. To prevent galling and seizing in low temperature, Stellite 6 overlay is recommended for Wedge seat surface. All base metal of seat ring and wedge or disc are followed trim material specifi ed with Austenitic stainless steel. As requirement, it can be equipped with PTFE or other soft material insert seat type to have tight off.
  • BONNET TYPE FOR GATE & GLOBE VALVE
  • HLC is supplying extended bonnet type having enough height to protect gland packing so that it prevent any leakage from back seat when it’s opened. In option, HLC is making Welded Pipe Connection Extended Bonnet type. The materials of pipe should be Austenitic Stainless Steel. You can make choice according to service.
  • DESIGN
  • Basically, HLC’s valves for cryogenic service is supplied with Heavy Wall Thickness Type based on API 600. This is to help valves have enough corrosion resistance and allowance compared with ASME B16.34. But according to customer’s requirement, it’s available with ANSI B16.34.
  • PACKING
  • Anti-exclusion square-braiding graphite fi ber top & bottom rings and pure graphite preformed packing to be provided all valves. In other option, there is PTFE but we can supply other materials considering using in cryogenic service.
  • APPLICAPABLE LIQUIFIED GASES
  • Anti-exclusion square-braiding graphite fi ber top & bottom rings and pure graphite preformed packing to be provided all valves
