Gate valves are widely used in water systems, such as water treatment plants, distribution networks, and potable water applications. They are also commonly found in sewage systems, including sewage treatment plants, raw water, and digested sewage. In industrial systems, they handle chemical waste, gases, and seawater. For food and beverage industries, they are suitable for washing, rinsing, and conveying systems.
