German Sferaco valves Sferaco models Sferaco prices
Sferaco valves, also known as globe valves, belong to the forced-sealing valve category. Therefore, when the valve is closed, pressure must be applied to the disc to ensure a leak-tight seal. When the medium enters the valve from below the disc, the resistance that the operating force must overcome consists of the friction between the stem and packing and the thrust generated by the medium pressure. The force required to close the valve is greater than the force required to open it; therefore, the stem diameter must be large enough to prevent bending failure. According to the connection method, they are divided into three types: flange connection, threaded connection, and welded connection. Since the advent of self-sealing valves, the flow direction of globe valves has changed.
Sferaco filter Germany Sferaco model Sferaco price
Sferaco filter wastewater treatment filter is suitable for the separation of solid suspended particles in liquids, especially in toxic media. The wastewater treatment filter mainly treats sewage to enable its reuse, effectively removing suspended solids with stable filtration accuracy. Applications of wastewater treatment filters include water supply and drainage systems in the metallurgical industry—continuous casting and rolling water systems, blast furnace water systems, turbid and clean circulating water systems, and makeup water systems; steam turbine cooling water systems in the power plant industry; boiler wet cooling water systems; cooling water systems for large air compressors, large oxygen generators, and large air conditioners.
