FCS003 Forged Steel Gate Valve Full Bore (Socket Weld / Screwed)

INTRODUCTION

Leader forged steel gate valves adopts solids gate, renewable seat, rising stem, and non-ring hand wheel. It plays the role of pipe opening and closing ultimately through the rotation of the hand wheel to drive the lifting of gate.

• Design Std API 602. BSEN ISO 15761, ASME B16.34.
• Pressure Temperature Rating as per ASME B16.34, API 602.
• Sturdy design for high-pressure & temperature service.
• The body is available in both the full and standard port design.
• Bolted body-bonnet O&S Yoke type rising stem design, Valves with welded bonnet also available on request.
• Bolted body-bonnet joints provided with spiral-wound stainless steel gasket and graphite filler for protection against leaks.
• Die-formed graphite inner packing rings and braided graphite end rings with Inconel wire reinforcement and corrosion inhibitor.
• T-head stem-disc connection of gate valve fully meets strength requirements of API 602 and API 598.
• Tapered shoulder on the stern for back seating.
• The gland, gland flange assembly utilizes a separate, two-piece design. This self-aligning design allows the flange to be unevenly tightened while the gland maintains its parallel alignment with the stem and stuffing box.
• The yoke sleeve is of forged stainless steel material having a high melting point and is resistant to wear and corrosion.
• Socket welded ends as per ASME B16.11.
• Screwed Female Taper ends as per ASME B1.20.1 (NPT)/BS 21 & Screwed Female Parallel ends as per ISO 228/BS 21 available on request.
• Socket-weld Class 800 Reduced Bore valves confirm to Class 3000 (or Sch.80/Sch.XS) fittings of ASME B16.11.
• Socket-weld Class 800 Full Bore valves confirm to Class 6000 (or Sch.160) fittings of ASME B16.11.
• Butt weld ends as per ASME B16.25 available on request.
• Robust construction of hand wheel in open spoke design.
• Valves can be offered with electrical actuators on request.
• Low-Temperature Carbon Steel & Austenitic SS forging for body and bonnet with extended bonnet design qualified as per BS 6364 for Cryogenic service available on request.
• Valves can be offered to NACE MR-0175 and other special NACE requirements.
• Valves are available with IBR certification.
• Low Emission, FET-qualified valves as per API 624/ISO 15848-1 can be offered with API 622 (FET), API 607 (Fire Safe) qualified gland packing.
