API 6D Gate Valve

‌RockySea Petro: A Pioneer in API 6D Gate Valve Manufacturing in China

Gate valve is a common form of valve in API 6D valves, which achieves flow switching by lifting the barrier (gate) out of the fluid path. When fully opened, flat gate valve hardly restricts the flow of fluid and is widely used in oil fields and industry.

RockySea has obtained API Q1, API 6D and ISO standards. RockySea has rich experience in manufacturing various gate valve and all products undergo 100% inspection before delivery.

Description

Gate valves are usually used to shut off the flow of liquid, rather than for flow regulation. When the valve is fully open, there are barely no obstacles in the flow path, so the flow resistance is also very low.

Principle

The opening and closing component of a flat gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted or throttled. 

The gate has two sealing surfaces forming a wedge shape. The wedge angle varies with the valve parameters. The gate plate of the wedge gate valve can be made into a whole, called a rigid gate plate. 

It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.

Application

The API 6D gate valve produced by RockySea is suitable for pipelines with ANSI Class150~2500, PN20~42, JIS 10~20K, and operating temperatures of -29~425 ℃ (carbon steel) and -40~500 ℃ (stainless steel). It is used to cut off or connect the medium in the pipeline. By selecting different materials, American standard carbon steel gate valves and stainless steel American standard gate valves can be suitable for various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea.

Advantage

1. The valve body material variety is complete, and the packing and gasket are reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
2. Reliable sealing and excellent performance.
3. Adopting a wedge-shaped elastic gate structure, equipped with rolling bearings for medium and large diameters, easy opening and closing.
4. The structural design is compact and reasonable, with a beautiful appearance.
5. It can meet various international flange standards and flange sealing surface types, meeting various engineering needs and user requirements.
