The HH49X micro resistance slow closing butterfly check valve is mainly used in the supply and drainage pipelines of clean water, source water, sewage, seawater, and other media. It is installed at the outlet of the water pump to cut off the backflow of the media and eliminate atomic energy damaging water hammer, protecting the safe operation of th1
Check valve refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent medium backflow, also known as a check valve, one-way valve, or backflow valve. A check valve is an automatic valve that primarily functions to prevent media backflow, prevent pump and drive motor reversal, and dis1

Product Introduction: 1、 Product details of micro resistance slow closing butterfly check valve: Product name: Micro resistance slow closing butterfly check valve Product features: Suitable for medium pipelines such as clean water, sewage, and seawater with a nominal pressure of 1 MPa and a medium temperature of ≤ 80%, as well as pressurized water 1
Introduction to Plug Valves: Three way plug valve cast steel plug valve uses a plug body with a through hole as the opening and closing component of the valve. The plug body rotates with the valve stem to achieve opening and closing action. The plug body of a rotary valve is mostly a circular body (sometimes a cylindrical body), which matches with 1
A check valve with a high-pressure check valve disc sliding along the vertical centerline of the valve body. Internal threaded check valves can only be installed on horizontal pipelines. On high-pressure small diameter check valves, a ball can be used as the disc. The valve body shape of a butterfly check valve is the same as that of a globe valve 1
