• Castle DN200 PN25 Ductile Iron Dual Plate Check Valve BSV4CWDGP25-G200-2 is a type of check valve that is used in many industrial applications to prevent backflow. This type of check valve uses two plates instead of one, which allows it to handle higher pressure while still preventing backflow. This check valve is also referred to as a double-acting or double-spring check valve because it uses two springs to open and close the valves
• A dual plate check valve has a small chamber between the two plates where fluid can flow when the device is open. The first plate is always held closed by spring pressure and can only be opened by pushing on the second plate. When you push on this second plate, it forces the first plate open and allows fluid to flow through the device. When you release pressure from this second plate, it pushes against its spring force and closes off all fluid flow through the device
• This type of check valve is ideal for applications where high pressures are involved because it can be made with very large springs that will resist any pressure that tries to push against them from either direction. This allows them to be used for everything from controlling liquid flow in industrial equipment like water towers or fuel tanks to controlling gas flow in industrial equipment like boilers or furnace
