Industrial Rubber Lined Diaphragm Valves are used for control applications where the performance of a valve is critical. The most common use for an Industrial Rubber Lined Diaphragm Valve is in water and wastewater treatment plants. They control water flow rates, provide liquid level monitoring and prevent the backflow of liquids. They can also be used to control airflow rates in ventilation systems. Due to their high reliability, they are also used in other industries, such as oil and gas extraction and processing plants, food and beverage manufacturing, waste processing and incineration plants.
They are also commonly found in home plumbing applications such as toilets, showers and kitchen faucets. Because Industrial Rubber Lined Diaphragm Valves perform critical functions at high temperatures, they are manufactured using special rubber materials that provide the necessary durability. Industrial Rubber Lined Diaphragm Valves come in both ball and butterfly designs. The most common design is a ball valve with a rubber diaphragm that prevents leakage or backflow of liquids by sealing against the valve's body when it is open.
