Check Valve supplier DH7cs41 hydraulic control check butterfly valve is an intelligent product developed with great concentration for the purpose of eliminating water hammer and protecting the safety of water pumps and pipe network systems. It is suitable for the outlet of large and medium-sized water pumps and the inlet of water turbines, pump valves or valves. machine linkage. 聽 The main features are 1. The lifting weight structure and the non-draining energy storage structure occupy a small space and are safe and reliable to use. 2. Mechanical and electromagnetic joint locking can effectively prevent the phenomenon of falling hammer. The working principle of the valve is: when the valve is opened, the force of the hydraulic station and the lifting cylinder is used to drive the butterfly plate to rotate 90 degrees through lifting arms, transmission pins, valve shafts and other parts. When the valve is fully opened, it will be locked by the electromagnetic force of the mechanical ejector rod, swing rod and electromagnet, so that the valve will remain fully open for a long time, ensuring that the hammer will never drop. Valve closing consists of two programs, fast closing and slow closing, and the whole process is completed in one go. The valve can be operated locally or controlled remotely. The operating status can be displayed and the operating result can be signaled. Its product performance is at the leading level at home and abroad. 聽 Product Specification Transmission MethodConnection TypeNominal Diameter Dn (mm)Pressure Range PN (MPa)Closing angleApplicable MediumApplicable Temperature 鈩?/p Material HydraulicDouble flange400-34000.6-1.6Quick close 75掳 Slow closing 15掳Clear water, Muddy water, Seawater-10~80Ductile iron, Carbon steel and stainless steel StandardJB/T5299銆丟B/T13927銆丟B/T17241.6銆丟B/T9115.1銆丟B12221 聽 Application Hydraulic control check butterfly valve is mainly used on pipelines where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.Check Valve supplier website:http://www.sinomachflange.com/valve/check-valve/
