SPECIAL SERVICES AND APPLICATIONS
API 6D - API 6DSS - API 6A - API 17D

Our valves are suitable for special services and applications such as subsea, low and high temperature, severe service, sour service and others. 

SUBSEA BALL AND GATE VALVES - API 6DSS / API 17D
› Additional environmental sealing at body to closure and body to stem
› CRA overlay on sealing or process wetted areas
› ROV interface to API 17H/ISO 13628-8 (optional)
› More stringent requirements for material selection
› Advanced inspection and testing requirements (i.e. hyperbaric testing, cycling)
› As per API 6DSS standard
› Available in Top-entry, Side-entry, Fully-welded, Twin ball valve design and Through-conduit gate valve design

 

LOW TEMPERATURE BALL VALVES TO -196°C (API 6D)
› Extended bonnet with vapor space to maintain the stem packing within the suitable temperature range.
› Low friction coating on seating for smoother operation
› Fugitive emission (FE) compliance
› More stringent requirements for material selection
› Supplementary inspection and testing (i.e. FE, Low temperature testing)
› Available in Top-entry, Side-entry, Fully-welded and Twin ball design

 

METAL-SEATED BALL VALVES (API 6D - API 6DSS)
› Suitable for severe service (dirty, abrasive), high temperature (<+500°C), low maintenance (subsea, underground), high demand (frequent cycling)
› Hard facing on ball and seats (ENP, TCC, CCC)
› Higher torque, more robust topwork design, more powerful actuator
› Leakage rates to API 598 or ISO 5208:1993, Rates A, B
› Available in Top-entry,  Side-entry and Twin ball design. Not available in Fully-welded design

 

CLADDED BALL VALVES (API 6D - API 6DSS)
› Suitable for sour service, harsh and hostile environment, low maintenance
› Corrosion resistant, long life, high reliability
› Overlay in Inconel 625 or Stainless Steel, mostly applied on Carbon Steel base material
› Cladding options: dynamic seal areas, all sealing areas, all wetted areas (fully cladded)
› Final overlay thickness of min. 3 mm.
› Available in Top-entry, Side-entry, Fully-welded and Twin ball  design
