The gate has a rigid gate and an elastic gateaccording to the different gate plates, the gate valve is divided into a rigid gate valve and an elastic gate valvea gate valve is a gate plate of an opening and closing partthe gate valve is sealed by the contact of the valve seat and the gate platestandards: en 593, api609, api6d,
more video of gate valve, please see: https://wwwthe movement direction of the gate plate is perpendicular to the direction of the fluidthe gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled
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:

gate valve features
advantages:
low flow resistance
the medium can flow in any direction on both sides, easy to installthe use of ptfe packing is reliable and easy to operate
the structure is compact, the valve has good rigidity, the channel is smooth, the flow resistance is small, the sealing surface is made of stainless steel and hard alloy, and the service life is longcom/watch?v=ai-lt1dy2su
materials: cast iron / ductile iron/ carbon steel / stainless
steel / alu bronze
pressure rating: pn10, pn16, pn25
temperature: -30°c to 200°c

large height and long opening and closing time
the structure length is small
gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenance
disadvantages
the overall dimensions and opening height are largethe 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, etc
less effort when opening and closingthe space required for installation is large
during the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches2 cert (on request)
standards
design and manufacture conform to awwa, bs5163, din-f4,f5
dimensions conform to en1092-2,ansi b16
the shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide
water hammer phenomenon is not easy to produceIndia
