SUBSEA THROUGH CONDUIT SLAB GATE VALVE
ATV manufactures a full range of Through Conduit Slab Gate Valves for Offshore & Subsea applications in the Oil & Gas exploration and production, suitable for water depths up to 3000 m (10000 ft).
Through Conduit Slab Gate valves provide superior bubble tight sealing capabilities in gas service and unmatched robustness in harsh services with high pressure, high temperatures and solid particles. The full bore through conduit design minimizes the turbolence of the flow and, when the valve is open, the pressure drop is equivalent to that produced by a pipe with the same diameter and length. Moreover, the valve is perfectly suitable for pigging operations.
ATV considers the through conduit slab gate valve the preferred choice for HIPPS applications, in consideration of the closing pressure assisted feature.
ATV supplies the through conduit slab gate valves in a wide range of materials and configurations to meet any specific need of the application and customer’s requirements. ATV slab gate valves are manufactured with hardfaced sealing surfaces with Tungsten Carbide Coating (TCC). Optional features are available for seat and stem seals, hardfacings and end connections. Materials are sourced from qualified suppliers on the base of specifications that reflect the industry standards (API, ASTM, BS, DIN, NORSOK or others), but do also incorporate additional requisitions resulting from long experience.
The through conduit slab gate valves may be manually operated (by ROV or by diver, if feasible) or fitted with linear hydraulic actuators, fail as is or fail safe, with or without ROV override. ATV offers the highest level of performance and reliability being its actuators engineered to grant safe and extended operating life.
ATV designs, manufactures and tests its products in accordance with all the relevant Industry standards and codes (ANSI, API, ASME, BS, DNV, ISO, NACE, PED and others). The slab gate valves can be manufactured to conform up to product specification level PSL 4.
ATV stresses its willingness to produce engineered slab gate valves; therefore it welcomes requests for special size, class and design requirements.
