Double-door Bottom Valve

タイトルまたは説明

This bottom valve is also called a check valve. The bottom valve is an accessory that must be used to prevent the return of liquid in the suction pipeline when the fuel tanker is stopped. It is suitable for all kinds of pump fluid body non return. This type of bottom valve is composed of one (single - door) or two door panels (double - door), which can be freely opened and closed under one - way flow conditions, so as to achieve one - way flow of fluid. As an important component in the fuel tanker, bottom valve is mainly used to control the flow of oil and prevent backflow to ensure the normal operation of the tanker. When the fluid enters the bottom valve from the inlet pipe, the door panel will automatically open and allow the fluid to pass through. When the fluid stops or changes direction, the door panel will close immediately to prevent reverse flow.

Feature:

• Simple structure: the single/double - door bottom valve is composed of a small number of parts, the structure is simple and compact, and it is easy to install and maintain.
• Corrosion resistance: bottom valves are usually made of corrosion - resistant materials, which can adapt to the use environment of various media.
• Good sealing performance: the door panels can completely seal the piping system when closed, effectively avoiding leakage.
• Low opening pressure: Since the bottom valve is closed by gravity, it only needs a small pressure to open under normal circumstances, thereby reducing energy consumption.
• Wide range of applications: bottom valves can be used in various fluid media and working conditions, and have a wide range of applications.
