Ball type check valve is used in pharmaceutical, food, beverage, environmental protection, chemical, metallurgy, petroleum and other industries to prevent the reverse flow of the medium in the pipeline and protect the safe operation of the equipment.
The rubber ball type check valve is suitable for water, steam, oils, nitric acid, acetic acid, strong oxidative media and urea and other mediums.
The ball type check valve is one of the best check valves used in sewage and drainage systems.
Ball type check valve is mainly composed of valve body, rubber ball, valve bonnet,etc. The rubber ball rolls in the valve body for a short stroke to realize the opening and closing of the check valve. When the water pump starts working, the rubber ball is moved to rise up to the bonnet by the water pressure, then the ball type check is open; when the water pump stop working, due to the return water pressure in the pipeline system, the rubber ball is forced to roll back to the left front valve body, then the check valve is closed.
