Company Information
Zhejiang weiguang pump&valve manufacture CO.,LTD started since 1992, manufacturing and supplying ball valve, butterfly valve, diaphragm valve, fluorine lined valves , PTFE lined pipes, PE/PO lined pipes , providing the company's customers with access to qualified products and an ISO 9001:2015 quality level resulting in approved valves in the market.
Ball valves are suitable for chemical and corrosion resistant conditions.
Butterfly valves are suitable for chemical and corrosion resistant conditions.
Diaphragm valves are suitable for chemical and corrosion resistant conditions.
Fluorine lined valves are suitable for chemical and corrosion resistant conditions.
Check butterfly valves the hydraulic controlled slow closing check butterfly valve is currently an advanced pipeline control equipment at home and abroad, mainly installed at the inlet of hydraulic turbines in hydropower stations and used as the inlet valve of hydraulic turbines; Or installed at the pump outlet of various pump stations such as water conservancy, electricity, water supply and drainage, to replace the function of check valves and gate valves. During operation, the valve cooperates with the pipeline host and, based on the principle of hydraulic transition process, achieves reliable cut-off of the pipeline through a preset opening and closing program, effectively eliminating water hammer in the pipeline and protecting the safety of the pipeline system.
