Hydraulic Control Butterfly Valve Slow Close only back at home and abroad are more advanced pipeline control equipment installed in the main hydropower station turbine imports, imports of used turbine valve; or installed in the water, electricity, water supply and drainage pumping station pumps and other types of export to replace the check valve and gate valve. Job, the host with the valve and pipeline, in accordance with the principles of hydraulic transition process, through the electro-hydraulic control procedures for the effective setting, reliable pipeline implementation deadline, the effective elimination of pipeline water hammer and can achieve no automatic electric valve clearance, to play pipeline system to protect the security role.
My company produces intelligent relieve heavy hammer-type hydraulic control valves closed only return to potential heavy hammer Kuan valve to automatically power source, the use of PLC intelligent control system, in accordance with user requirements and the installation of manual, automatic locking devices, flow the resistance coefficient of small, high degree of automation, full-featured, performance is stable and reliable, are in my extensive research, study, sum up the performance of similar products at home and abroad on the basis of the introduction of valves, hydraulic, electrical and other industries of a number of research results, plot thick and thin hair, developed a new generation of intelligent and efficient energy-saving products.
