As the practitioner and forerunner involved in the localizing manufacturing long distance transmission pipeline check valve,Dipper Valve has ploughing in check valve field over ten more years,we already had very good reference in axial flow check valve,piggable check valve,cryogenic check valve as well as slurry check valve fields, forms over ten unique manufacturing technical and multiple patents,piles of products applied to Natural Gas,Crude Oil,LNG and slurry pipeline,these products ensured the long distance transmission pipeline safe and reliable running,at the meantime,it drive forcefully the localizing manufacturing long distance transmission pipeline check valve.
Pig Valve is one of the most proud main product of Dipper Valve. As the professional device to cleaning,separating transportation,different diameter pipe pigging,switching and transportation,protect inner floating proof tank,pig valve has showed its huge value in application as well as advantage in comprehensive cost/performance ratio at the application which required launching or receiving pigs. At the time,Dipper Valve has create this detail market, it is also established its leading position with piles of unique honours. Besides of bypass pig valve,cleaning pig valve and separating pig valve,we also supply different diameter pig valve,three way pigging valve these with Dipper Valve patent products.
The emergency shutdown valve it is an essential safety protect device working at petroleum and natural gas well site. It is aims to reliable shutdown natural gas, regulator station, long transmission pipe transportation,so that protect pipeline and equipment safety running. When system pressure higher than the highest limitation or lower than the lowest limitation,the valve will automatically closed to prevent natural gas (medium) leakage. Dipper Valve can provide ball valve type ESD valve as well as global type ESD valve according to different application to safety protect wellhead, station and equipments.
Over last ten more years,Dipper Valve has dedicated himself to research in special valves,research and develop product suitability at various application and core technic such as product reliability, stability and durability,with its continuously technical innovation to guarantee the product high quality and provide client outstanding performance special ball valve product and service. Its meticulous and intensive ploughing in slurry transportation,chemical processing of coal, polycrystalline silicon, petrochemical industry, create Dipper Valve special ball valve system which representative by ball valve for abrasive application,slurry ball valve,crogenic ball valve,super high pressure ball valve.
Based on the understanding of pipeline transportation and surge application,as well as valve supply experience,combine with deep research on axial flow check valve structure and piles of applications,Dipper Valve researched and developed axial flow type pilot operated surge relief valve as well as gas loaded relief valve.based on the platform of “oil and gas pipe key equipment localizing manufacturing project”,we have undertook the localizing manufacturing project of gas loaded relief valve,this research valve has passed the national energy bureau technical verification,meet the overseas made same kind products technical level,this product will promote and apply to oil transportation pipeline and other liquid transportation pipeline.
The NDIV rising stem ball valve is a non friction and low torque ball valve which utilize the stem to control the core tilting and rotation.since the birth of this kind of valve,with its non friction and low torque advantage,it is widely applied to sever application where big differential operation pressure happens,frequently operation,pressure and temperature request valve in good sealing at long term or not allowed downtime maintenance or replace valve application, such as petroleum, chemical,city water supply and drainage application. The NDIV Rising Stem Ball Valve has successful passed national localizing manufacturing project verification,it is manufactured by multiple independent intellectual property rights,it is a reliable product to serve application ,and provide reliable service capability.
The centrifugal pump normally are working under changeable flow rate,when the centrifugal pump working under low load,the overheating,serious noise,unstable working and cavitation erosion which may damage the pump could happen.The automatic recirculation valve is a minimum flow control valve to maintain centrifugal pump required minimum flow rate,it is a device to protect the centrifugal pump in good working,Dipper Valve automatic recirculation valve with:flow rate sense , re-circulation control,bypass multi-level pressure relief as well as prevent backflow function,it is a reliable choice to prevent centrifugal pump.
