These gate valves, either used above or below ground, are engineered for reliability in potable water systems, industrial pipelines, and municipal infrastructure. Available in resilient-seated (soft sealing) or metal-seated (hard sealing) configurations, these valves …

Metalsin supplies motorized wafer butterfly valves with electric actuators to water supply and water treatment pipelines. They are also known as electric actuated wafer butterfly valves. The term “motorized” refers to that the valve is operated by an electric actuator, which serves as the driving force by converting electrical energy into mechanical motion to rotate the valve disc. It typically …

Metalsin supplies versatile pneumatic-actuated lug butterfly valves for waterworks applications. These valves feature the pneumatic-actuated operation method: The butterfly valve is driven by a pneumatic actuator, which is a device that uses compressed air to automate the operation of the valve, enabling it to open, close, or modulate flow. Pneumatic actuators are widely used in waterworks applications due to their …

Design Features Metalsin supplies EN 593 double eccentric butterfly valves to waterworks applications, which are gear operated with double flanged ends.
