We are the provider of high-class 15 NB piston valves. These valves are flow-regulating devices that control the fluid flow inside a pipeline. They are commonly employed in scenarios where fluids must function in either a fully closed or fully open state, such as in water pipelines. Due to the fact that a packing gland is not needed to seal the stem, piston valves provide excellent protection against atmospheric leaks. In power plants, refineries, pulp and paper mills, and municipalities, piston valves are mainly utilized for hot water, regular water services, and saturated and superheated steam. Additionally, they can be used to handle gases like hydrogen, nitrogen, and oxygen.
