Product Specification

Production Description:

API 6A gate valve

In the context of API 6A, a hydraulic gate valve is a type of gate valve that utilizes hydraulic pressure to control the opening and closing of the valve. It is commonly used in oil and gas wellhead and Christmas tree systems, as well as other applications in the industry.

API 6A sets forth various requirements and tests for hydraulic gate valves to ensure their suitability for the harsh operating conditions and process requirements in the oil and gas industry. These requirements may include specifications for materials, design, dimensions, pressure ratings, temperature ranges, sealing performance, operating mechanisms, and more.

API 6A hydraulic gate valves typically exhibit the following features:

1. High-pressure capability: They are designed to withstand high-pressure environments, making them suitable for high-pressure well operations or deepwater installations.
2. High-temperature capability: They can operate reliably in high-temperature environments encountered during oil and gas production processes.
3. Reliable sealing: They have excellent sealing performance to effectively control fluid flow.
4. High strength and corrosion resistance: They are constructed with high-strength materials and may have special coatings to provide long-term stability and resist corrosion.
5. Remote control: They can be operated remotely through hydraulic systems, enabling convenient operation and monitoring.

It's important to note that API 6A is a specification, and manufacturers of hydraulic gate valves need to adhere to this standard during the design, manufacturing, and testing processes. If you are looking for API 6A hydraulic gate valves, it's recommended to contact suppliers or manufacturers who specialize in producing valves that comply with API 6A to obtain more specific information and product details.

Gate valves are designed to meet the customer's demand for high-quality, reliable, and reasonably priced valves. All gate valves of Zhengxuan are manufactured by fully utilizing modern raw materials and processing techniques. It is easy to maintain and fully complies with international design requirements and quality assurance. All gate valves are manufactured in workshops that comply with API Q1 and ISO 9001 certifications based on API 6A standards.

All valve bodies and covers are machined from cast or forged AISI4130 or AISI410. Other special materials, such as Inconel stainless steel or duplex stainless steel, can also be used according to customer requirements.

The valve plate and valve seat are precisely ground to ensure reliable sealing between metal surfaces.
The expansion flat valve is designed with an elastic sealing surface on the valve seat to match the flow seal, ensuring that the valve seat is tightly wedged into the valve seat opening or closing.

All gate valves are bi-directional sealed, with no risk of pressure leakage, and have good sealing performance against pressure in all directions.
The valve stem seal is a non elastic seal, suitable for most fluids and gases. The valve stem using PTFE/R-PTFE sealing device has low operating torque due to its reduced frictional resistance. The valve stem seal can also use graphite material according to the actual applicable temperature environment.
