Valve-related parts are parts such as flanges and packing that are used together with valves. Valves must be inspected and cleaned, and consumable parts must be replaced. These parts include water hammering stoppers used to reduce water hammering in the water supply pipes of high-rise buildings and apartment buildings, and control panels for emergency shutoff valves that are used to shut off the water tank in an emergency. Valve consumables include flanges, packing and drain plugs. The role of flanges and packing is to fill the gap between pipes, and connect valves and pipes. A drain plug is a screw for covering the discharge port for oil or wastewater. Select valve related parts according to the application and required parts. Using these parts appropriately will help reduce risks such as fluid leaks and system risks in an emergency.
