MAIN FEATURES: The two sealing faces of a slab gate valve are perpendicular to the pipeline axis, its closing member have double discs, valve equipped with a stretching mechanism. The gate valve is widely applicable for transmission pipeline system of natural gas ¡¢oil products and chemical engineering. The valve obturator have two parts, the seal surface are parallel each other, and with wedge-shape joint surface. The obturator parts are separated from each other, it can ensure the sealing performance even when the temperature changes caused by deformation, and can avoid leaving the gate due to heat expansion choked open. At sealing surface using hard alloy material of corrosion and wearing resistance, so it can ensure the sealing performance and extend the service life. Fully enclosed structure design, keep the valve fine protection, can be used at all weather. Design Features Design standard as per: API 6D¡¢ASME B16.34¡¢GB/T 19672 its performances as small operation torque, better sealing, lower noise during operation, safety and reliable operation; The valve disc and valve seat seal are repeatedly treated by special processes, and protected by multiple seals, and featured with anti-corrosion, penetration-proof, anti-abrasion and long service life; Valve seat is designed with hard-soft double seal, having reliable tightness; With a full bore design, both the coefficient of flow resistance and the pressure loss are very small; When the valve is fully opened, medium erosion occurring to its sealing face is smaller than that of other valves; The through conduit gate valve with diversion holes installed on a pipeline can also be cleaned by a pipe cleaner directly; No space restriction on valve installation, that is, both parallel and perpendicular installations are allowed. Product Range Body material: carbon steel, stainless steel, Nominal diameter: 2"¡«36" Pressure range:Class150¡«2500 End connection: RF, RTJ, BW Working temperature:-46¡æ¡«+200¡æ Operation : handwheel, gear box, electric, pneumatic actuator, electro-hydraulic actuator , etc.
