Product Description Product DescriptionProduct IntroductionA knife gate valve, also known as a knife - edged gate valve, is a type of valve where the closing member is a blade - shaped gate. The movement direction of the gate is perpendicular to the fluid direction. It cuts off the medium by means of the blade - shaped gate that can cut fibrous materials. The gate has two sealing surfaces, and in common knife gate valves, the two sealing surfaces form a wedge - shape, with the wedge angle varying according to valve parameters, usually 5°. During closing, the sealing surfaces can achieve sealing relying on the medium pressure (self - sealing) or external force (forced sealing).Structural FeaturesValve Body: Made of various materials such as cast iron, cast steel, carbon steel, stainless steel, and fluorine - lined materials. Some valve bodies are spray - painted for anti - corrosion, anti - wear, and dust - proof purposes.Gate: Made of materials capable of cutting fibrous materials. Some gates can be made into elastic structures to compensate for machining deviations of the sealing surface angle.Seals: Available in hard seals (such as metal seals) and soft seals (such as rubber and fluoroplastic seals). There are also different sealing forms like single - sided sealing and double - sided sealing.Actuating Devices: Options include manual, chain - wheel, electric, pneumatic, hydraulic, bevel gear, electro - hydraulic, and pneumatic - hydraulic actuation.Product SpecificationsSize: Common nominal diameters range from DN50 - DN2000, and products with a wider range are also available.Pressure: Nominal pressure typically ranges from PN1.0 - 16.0MPa, with different models corresponding to different working pressures.Temperature: The working temperature range varies depending on the sealing pair material and medium. Generally, it can be 0 - 1100oC, and there are also ranges like - 196oC - 425oC.Performance AdvantagesSpace - Saving: Compact structure requires less installation space.Low Flow Resistance: Allows smooth medium flow with low energy loss.Less Debris Accumulation: Special structure prevents debris from easily staying inside.Lightweight: Some bodies are made of carbon steel and other materials, reducing weight by 20% - 30% compared to traditional gate valves, facilitating installation and maintenance.Long Service Life: Sealing surfaces are made of highly wear - resistant and corrosion - resistant materials like ceramics. Through inlaying technology, they have good corrosion and wear resistance.Versatile Functionality: Has dual functions of shut - off or shut - off + throttling. Some can lift the gate sealing surface to scrape off adhered substances and automatically remove debris.Application FieldsMining and Steel Industry: Used in pipeline systems for coal washing, gangue discharging, slag discharging, filter residue slurry handling, and ash discharging.Sewage Treatment: Controls the flow of sewage and other media in urban sewage treatment systems.Paper - making Industry: Suitable for pipelines transporting pulp and stock - water mixtures of any consistency.Power Stations: Applied in ash - removal system pipelines for ash - slag slurry.Chemical Industry: Used in pipeline systems of the petroleum, chemical, and pharmaceutical industries to cut off or open fluid media.Others: Also used in water conservancy projects to regulate water flow, in thermal engineering to adjust boiler medium flow, and in urban water supply networks to control water supply pressure and flow.Execution StandardsThere are corresponding national standards for aspects such as the pressure - temperature rating of shell materials, the structural length and limit deviations of the valve body, the connection dimensions and sealing surface types of flanges, and the dimensional tolerances of valve stems and valve stem nuts, such as GB 9131, GB/T 15188.2, etc. Packaging & Shipping Company Profile Rooted in a legacy of excellence, Tianjin Auswell Valve Co., Ltd. proudly adheres to a multitude of international standards including those from China, Germany, Britain, America, Japan, and Australia.
