Product Description: Zigong Zipump Water Pump Suction Shower Head H42X or H41X Flange Lift Bottom Check Valve, One-Way ValveThe 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.The main function of the bottom valve is to prevent medium backflow, prevent the pump and its drive motor from reversing, and to discharge the medium in the container. Check valves can also be used on pipelines that supply auxiliary systems where the pressure may exceed the main system pressure.Depending on the material, check valves can be used on pipelines for various media.When installed on a pipeline, the check valve becomes one of the fluid components of the complete pipeline, and the opening and closing process of its valve disc is influenced by the transient flow state of the system it is in; conversely, the closing characteristics of the valve disc also react to the fluid flow state.H42X Bottom Valve Structure and Principle: H42X bottom valve consists of components such as the valve body, valve disc, valve cover, bushing, and sealing ring. Water from the source enters the valve body through the valve cover; under the pressure of the fluid, the valve disc opens to allow water flow. When the pump stops, the pressure in the outlet pipe quickly closes the valve disc, preventing the liquid from flowing back to the source, thus ensuring smooth water pumping and saving water energy loss.H42XNominal Pressure: PN0.25MPa~PN2.5MPa; Nominal Diameter: DN15～DN300Applicable Media: Water, oil, and non-corrosive media; Applicable Temperature: ≤50℃Other Common Flange Lift Bottom Valve Models: H42X rubber-sealed bottom valve, H42F fluoroplastic-sealed bottom valve, H42H hard-sealed bottom valve with stainless steel Cr13 sealing surface, H42W hard-sealed bottom valve with valve body as the sealing surface, H42Y hard-sealed flange lift bottom valve with hard alloy sealing surface;Valve Body Materials: Ductile iron bottom valve, cast steel bottom valve, stainless steel bottom valve, carbon steel bottom valve.Supplier: Zigong Zipump Ball Valve Water Pump Co., Ltd.

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.
