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 |
