Exceptional Attributes of the DN 2000 Vanne papillon
Le GGG50 – type DN 2000 butterfly valve showcases a plethora of outstanding features. Structurally, it incorporates a double – eccentric sealing mechanism with an auto – sealed configuration. Equipped with a standard valve stem, it is engineered to function optimally under low – pressure conditions (Pn<1.6amp) and within a normal – plage de température (-40°C<J<120°C). The soft – sealed surface not only guarantees a leak – tight seal but also enables smooth operation. Constructed with a cast – corps, it adheres to international benchmarks such as API609, DIN3354, BS5155, and En593.
This butterfly valve stands out for its high – capacity performance, facilitating large – scale fluid flow with minimal pressure drop. Crafted from heavy – duty materials like cast steel or stainless steel, it offers high – performance sealing alternatives. Operationally, it exhibits remarkable flexibility, being adaptable to hydraulic, pneumatique, or electric actuation systems. Its applications span across various sectors, including hydropower plants for regulating water flow in turbines, large – scale HVAC systems for managing air and water circulation, and municipal water systems for overseeing water distribution in urban areas.
Characteristics of the China Big Size Gate Valve
Inversement, le vanne à vanne de grande taille has its own set of characteristics. Gate valves are renowned for providing a straight – through flow path when fully opened, which can be advantageous in certain applications where minimal disruption to the flow is crucial. Cependant, in contrast to the DN 2000 vanne papillon, gate valves typically have a slower operation speed, particularly when manual operation is involved.
Operational and Maintenance
The DN 2000 butterfly valve from TWT Valve features a manual driving mode with worm – gear operation, as exemplified by the DN900 size, demonstrating its operational versatility. It has a flange – connection design in line with En593. The flange drilling complies with En1092 Pn16, and the face – à – face dimension adheres to En558 13 Série. To safeguard against rust, the valve is coated with epoxy, and additional anti – rust measures include applying anti – corrosion coatings during maintenance and implementing cathodic protection. When not in use, it is advisable to store the valve in a dry environment.
