DN1200 Large Size Double Wedge Gate Valve With Bypass

Large Size Gate Valve Product Usage

Large diameter gate valve using the highest quality ductile iron or carbon steel casting, high strength, high weight, precise geometric dimensions, ram interchangeable features, the installation of spiral bevel gear and effort instutions, one can very easiythe ground switch can also be based on the user´s requirements, installation of opening and closing direction column, or electric, pneumatic systems, municipal construction and mining, metallugry, power plants and other industries.

Large Size Gate Valve Product Features 

Light weight: This valve is made by ductile iron in resin sand shape, with high strength and low load, the weight of the valve is 20%~30% lower than a traditional gate valve, which can be installed and maintained very conveniently.

Plain seat: The seat of a traditional gate valve is normally hollow type that increases fluid resistance sily piles up sundries like welding slag, stone, mud and sand etc, which is bad for seal and fluid face. However, the resilient seated seal gate valve produced by our company  adopts a design of plain base type and straight through whole basin type which equals straigh pipes. It doesn't  easily pile up sundries, ensuring reliable seal and making fluid flow smoothly.

Disc overall packaged with rubber: The valve disc adopts high quality rubber to package itself overall both inside and outside, the European top-ranking rubber vulcanization technology can not only make vulcanized valve ensure precise dimensions but also make rubber and ductile iron wedge bond and coat tightly, not easily coming off and having good memory of resilience.

Disc overall packaged with rubber: The valve disc daopts high quality rubber to package itself overall both inside and outside, the European top-ranking rubber vulcanization technology can not only make vulcanized valve ensure precise dimensions but also make rubber and ductile iron wedge bond ang coat tightly, not easily coming off and having good memory of resilience,

Precise casting body: Body uses precise casting so that accurate dimensions can make body's inner part without any machining, ensuring good function of seal. Framework of the valce plate applies ductile iron, packaging with rubber overall, which owns accurate dimensions, tight bonding and coating, ang good memory of resilience. It is not coming off ang can interchange.

Anti-corrosion: The body's inside and outside adopt pulverous epoxy resin to do coating. The inner part uses stainless steel and copper alloy to prevent the corrosion and rusty, which can be used for sewage system and rusty, which can be used for sewage system and severe environment like underground.

Not easily crumbled: The traditional cast iron gate valve is normally caused to crumble by hitting, crashing and heavy pressing, etc. Use of ductile iron material, reduce most of such condition.

O ring seal ring: Body adopts the design of three layers of "O" type seal ring, which can reduce friction resistance caused by opening and closing, lessen leakage greatly and change the seal ring under the condition of water supply.

Product Advantages

Enhanced Durability and Corrosion Resistance

The DN1200 Large Size Gate Valve boasts superior corrosion resistance due to its pulverous epoxy resin coating and the use of stainless steel 

and copper alloy components. These materials ensure the valve can withstand aggressive media and high-pressure environments, making it 

ideal for sewage systems and other industrial applications where long-lasting performance is essential.

Low Maintenance and Efficient Operation

With its innovative design, the Double Wedge Gate Valve minimizes friction, ensuring smooth operation with minimal wear and tear. The resilient

 seat design prevents debris buildup, reducing the risk of valve failure and ensuring that maintenance requirements are minimal. This makes it an

 efficient and cost-effective choice for long-term use.

High-Performance Sealing

The valve’s double wedge design, combined with high-quality rubber vulcanization, ensures that it provides a tight, reliable seal even under

 fluctuating pressures. This feature significantly reduces the risk of leakage and ensures optimal flow control in high-pressure applications,

 increasing the efficiency of water and gas distribution systems.
