The gate valve is designed for applications in wastewater treatment systems and is also suitable for industrial use. Available in sizes PN 1/1.6/2.5/4/6/10 and DN 50 to 1200, it is made of ductile iron with stainless steel and zinc-free bronze components, providing excellent resistance to corrosive environments. This valve features a metal seat compliant with EN 1171, dimensions according to EN 558 base series 14, and a flange connection per EN 1092-2 PN 10. Additionally, it is equipped with a handwheel, adjustable stem sealing, and a purge screw. A reducer is required for DN 400, DN 700, and DN 1200 models when the operating torque reaches the nominal torque. The internal and external epoxy resin coating ensures durable protection against corrosion.
