Subsea Side Entry Ball Valve

A compact and cost effective solution for many high flow subsea applications.


  • Compact envelope
  • Reliable performance
  • Suitable to high pressure and high temperature
Subsea Side Entry Ball Valve

ATV designs and manufactures a full range of Side Entry Ball Valves, trunnion mounted, two pieces, for offshore subsea applications in the Oil & Gas exploration, production and transmission, suitable for water depths to 3000 m (10000 ft).  

Side Entry Ball Valve offers the advantage of a compact envelope, reliable performance and a cost effective solution. Typically, soft-seated configuration is available for clean service whereas metal-to-metal sealing is the preferred choice for highest reliability in harsh service with the presence of solid particles, high pressure and high temperature. ATV supplies Ball Valves in a wide range of materials and configurations to meet any specific need of the application and customer’s requirements. Many optional features are available for seat designs, seat and stem seals, 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 subsea ball valves may be manually operated (by ROV or by diver, if feasible) or fitted with hydraulic actuators, rack and pinion or helical spline design, with double acting or fail safe, with or without ROV override. Retrievable design is available in order to have the possibility to declutch the actuator and retrieve it to the surface or reposition it on another valve, without affecting the production line. ATV provides different proprietary design for ROV bucket or diver retrievability, while the interface for the landing tool will be made to the user’s design. 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). ATV ball valves can be manufactured to conform product specification level up to PSL 4.

ATV stresses its willingness to produce engineered ball valves; therefore it welcomes requests for special size, class and design requirements.
