Through Conduit Slab Gate Valve The valve seat of Through Conduit Slab Gate Valve adopts a two-way sealing seat, mainly with a metal seat seal, supplemented by a soft seat seal as the second type of seal, and the gate is designed with diversion holes and non-diversion holes. It has the characteristics of rational design, compact structure, sulfur resistance, corrosion resistance, wear-resistant, reliable sealing, and light torque of switches, easy-to-use. Through Conduit Slab Gate Valve is widely used in oil, natural gas long-distance pipelines and gas fields as open/close control valves.Get more news about through conduit gate valve,you can vist our website! Through Conduit Slab Gate Valveadopts full-caliber design, with single-board and double-board structure. ● It is a valve used for forging or casting the valve body. ● This valve has two-way opening and closing, reliable sealing, flexible opening and closing. ● It has the advantages of reliable sealing, low friction and high carrying capacity ● Its fire safe design to API 6FA/ API 607. Through Conduit Double expanding Gate Valves are double block and bleed valves as they can grant zero leak towards the body cavity with pressure on the upstream and downstream side, even when the valve is fully open. Solid particles cannot penetrate into the body, both when the valve is in the open or in the close position. Furthermore, they provide superior bubble tight sealing capabilities and unmatched robustness in harsh services with high pressure and high temperatures. 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 supplies the through conduit double expanding gate valves in a wide range of materials and configurations to meet any specific need of the application and customer's requirements. 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, 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: in such a case 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. ATV designs, manufactures and tests its products in accordance with all the relevant Industry standards and codes (ANSI, API, ASME, BS, ISO, NACE, PED and others). ATV through conduit double expanding gate valves can be manufactured to conform up to product specification level PSL 3/3G.
