large height and long opening and closing time
the structure length is small
area of application
marine industry, water supply & drainage, fire fighting, shipbuilding, water treatment, power stations, energy, food, chemical, and other systems
data sheet of gate valve:
type: wafer, double flange
size & connections: resilient seated: dn50 to d600
metal seated: dn50 to dn1200
medium: waste water, water, seawater, air, inert gas, oil
gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenance
disadvantages
the overall dimensions and opening height are largethe movement direction of the gate plate is perpendicular to the direction of the fluidthe reason is the long shutdown timeusually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1cr13, stl6, stainless steel, etcthe gate valve is sealed by the contact of the valve seat and the gate plate
less effort when opening and closingthe gate valve can only be fully opened and fully closed, and cannot be adjusted or throttledthe gate has a rigid gate and an elastic gatethe space required for installation is largeaccording to the different gate plates, the gate valve is divided into a rigid gate valve and an elastic gate valve
during the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches2 cert (on request)
