Company: 自贡自泵球阀水泵有限公司

Product Description: Sichuan Zigong Valve H41H or H44W Flange Swing Check Valve Non-Return Valve One-Way ValveBefore consulting or purchasing, users are requested to provide accurate parameters such as caliber, pressure, connection method, operation method, and main body material. The above prices are reference prices, and prices vary for different models. Additionally, this product is a customized product with a production cycle, and delivery times also vary. Therefore, for specific model prices and delivery times, please call for consultation.Swing check valves, also known as one-way valves or non-return valves, are used to prevent the backflow of media in pipelines. The opening and closing components automatically open or close based on the flow and force of the medium to prevent backflow. Check valves belong to the category of automatic valves and are mainly used in pipelines where the medium flows in one direction, allowing the medium to flow only in one direction to prevent accidents. This type of valve should generally be installed horizontally in pipelines.The disc of a swing check valve is disc-shaped and rotates around the axis of the valve seat channel. Due to the streamlined internal channel, the flow resistance is lower than that of lift check valves, making it suitable for large-diameter applications with low flow rates and infrequent changes in flow. However, it is not suitable for pulsating flow, and its sealing performance is inferior to that of lift check valves. Swing check valves are divided into single-disc, double-disc, and multi-disc types, primarily categorized based on valve caliber to reduce hydraulic impact when the medium stops flowing or backflows.Swing check valves adopt an internally mounted rocker arm swing structure, with all opening and closing components installed inside the valve body. Except for the sealing gaskets and sealing rings at the middle flange, there are no external leakage points, reducing the possibility of valve leakage. The connection between the rocker arm and the disc uses a spherical structure, allowing the disc to have a certain degree of freedom within a 360-degree range and providing appropriate micro-position compensation.Suitable for clean media, not suitable for media containing solid particles or with high viscosity.Nominal pressure PN1.0MPa~42.0MPa, Class150-2500;Nominal diameter DN15~1200mm, NPS1/2~48;Operating temperature -196~540℃ for various pipelines,Valve body materials: WCB, CF8(M), CF3(M), 1Gr5Mo, 15CrMo1V.Common models: H44H-16C H44H-40C H44H-64C H44H-100C; H44Y-16C H44Y-40C H44Y-64C H44Y-100C; H44W-16P H44Y-40P H44Y-64P H44Y-100PSuitable for various media such as water, steam, oil, acid solutions, highly oxidizing media, and urea. Mainly used in pipelines for petroleum, chemical, pharmaceutical, fertilizer, and power industries.Supplier: Zigong ZIPU Ball Valve Pump Co., Ltd. ZIPO VALVE & PUMP CO., LTD more>
