ATV manufactures a full range of Through Conduit Slab Gate valves for on-land applications in the Oil & Gas production, processing and transmission.

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 supply 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). Many 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 (ASTM, NORSOK, BS, DIN or others), but do also incorporate additional requisitions resulting from long experience.  

Through Conduit Slab Gate valves are suitable for manual operation or for power assisted operation. ATV takes full responsibility in selecting the most suitable size for operating conditions. However, ATV welcomes customers supplied items too: ATV responsibility is limited to the assembling of the actuator on the valve and testing of valve and actuator system. On request, ATV may participate in the actuator selection together with the customer. 

Materials are sourced from qualified suppliers on the base of specifications that reflect the industry standards (ASTM, NORSOK, BS, DIN or others), but do also incorporate additional requisitions resulting from long experience.  
ATV designs, manufactures and tests its products in accordance with all the relevant Industry standards and codes (API, ANSI, ASME, BS, ISO, NACE, PED and others). ATV Through Conduit Slab Gate valves are manufactured to conform to API 6A product specification level PSL 3/3G and pressure tested to either API 6A or API 6D requirements.

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