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:
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
related types of valves:
we can also produce check valve, globe valve, knife gate valve and ball valve with api, jis, din standard, used in oil, gas, marine industry, water supply and drainage, fire fighting, shipbuilding, water treatment and other systems, with nominal diameter of dn50 to dn1200, nbr/epdm/viton, certificates & approvals: dnv-gl, lloyds, dnv, bv, api, abs, ccs5

gate valve features
advantages:
low flow resistance
the medium can flow in any direction on both sides, easy to installusually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1cr13, stl6, stainless steel, etc
gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenancecom/watch?v=ai-lt1dy2su
less effort when opening and closing
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 long
the shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide2 cert (on request)
standards
design and manufacture conform to awwa, bs5163, din-f4,f5
dimensions conform to en1092-2,ansi b16
during the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches
large height and long opening and closing time
water hammer phenomenon is not easy to producethe space required for installation is large
disadvantages
the overall dimensions and opening height are large
materials: cast iron / ductile iron/ carbon steel / stainless
steel / alu bronze
pressure rating: pn10, pn16, pn25
temperature: -30°c to 200°c
seat/lining: replaceable liner / bonded liner
nbr/epdm/viton; ss/bronze
certificates & approvals: dnv-gl, lloyds, dnv, abs, bv type approval
3the use of ptfe packing is reliable and easy to operatethe reason is the long shutdown time
the structure length is smallIndia
