DIN Gate Valve is a gate valve manufactured by China gate valve enterprise according to German standard. The marine standard gate valve is the superior product of Chinese valve enterprise.
The opening and closing part of the German standard gate valve is the gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The gate valve has small fluid resistance, applicable pressure and temperature range, unrestricted flow direction of the medium, and good sealing performance. It is widely used in food, medicine, water treatment, chemical, natural gas, steel, environmental protection, papermaking and other transportation pipelines to cut or circulate media.
