orged steel gate valves adopt 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.
- 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 and rings with Inconel wire reinforcement and corrosion inhibitor.
- The t-head stem-disc connection of gate valve fully meets strength requirements of API 602 and API 598.
- Tapered shoulder on the stem 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.
- Flanged ends as per ASME B16.5 Raised Face.
- 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 624/150 15848-1 can be offered with API 622 (FET), API 607 (Fire Safe) qualified gland packing.
