Gate Valves – Flange Rubber Plate Gate Valve & Elastic Seal Gate Valves

Mar 27, 2023 | news

When it comes to selecting the right gate valve for your industrial applications, one important consideration is the sealing mechanism. Flange rubber plate gate valves and elastic seal gate valves are two commonly used types of gate valves that use different sealing methods. As leading China flange rubber plate gate valve manufacturer, not only we sale quality gate valves, but we also could tell you more about fire gate valve. In this post, we will compare the two types and highlight the advantages and disadvantages of each.

Gate Valve From Flange Rubber Plate Gate Valve Manufacturer

Flange rubber plate gate valves use a flat rubber plate to seal the valve. When the valve is closed, the rubber plate is pressed against the valve seat, creating a seal. The plate is held in place by a metal gate that moves up and down to open and close the valve.

China flange rubber plate gate valve advantages

  • Simple design – flange rubber plate gate valves have a simple design, which makes them easy to install and maintain.
  • High flow capacity – these valves have a large flow capacity and are ideal for applications that require high flow rates.
  • Low cost – flange rubber plate gate valves are generally less expensive than elastic seal gate valves.

Disadvantages of Flange rubber plate gate valve

  • Limited temperature and pressure range – these valves are not suitable for high-temperature and high-pressure applications.
  • Limited sealing ability – the rubber plate can become damaged over time, leading to leakage.

Detail Of Elastic Seal Gate Valve

Elastic seal gate valves use an elastic material, such as rubber or elastomer, to create a seal. When the valve is closed, the elastic material is compressed against the valve seat, creating a tight seal. The gate is held in place by a metal plate that moves up and down to open and close the valve.

Advantages of elastic seal gate valve

  • High sealing ability – elastic seal gate valves provide a tight seal that is resistant to leakage, making them ideal for applications that require a high degree of sealing.
  • Suitable for high-temperature and high-pressure applications – these valves are designed to withstand high temperatures and pressures, making them suitable for a wide range of applications.

Elastic seal gate valve disadvantages

  • Complex design – elastic seal gate valves have a more complex design than China flange rubber plate gate valve, which can make them more difficult to install and maintain.
  • Higher cost – elastic seal gate valves are generally more expensive than flange rubber plate gate valves.

Summary Of How To Choose Right Gate Valve

When it comes to selecting the right gate valve for your industrial applications, it’s important to consider the sealing mechanism. Flange rubber plate gate valves are ideal for low-temperature and low-pressure applications. This applications require a simple design and a high flow capacity. Elastic seal gate valve are suitable for high-temperature and high-pressure applications that require a high degree of sealing, although they are more complex and expensive. Ultimately, the choice between the two types of gate valves will depend on your specific application requirements and budget.
