Didtek 4130 Flange FC Single Acting Pneumatic Actuator API6A Forged Steel Ball Valve

Product Overview

This is a high-performance, high-pressure industrial ball valve, mainly designed for harsh working conditions, such as oil and gas extraction and production (wellhead equipment). It combines a forged steel valve body and a single-acting pneumatic actuator, which automatically opens or closes the valve by receiving pneumatic control signals.

Detailed explanation of core components

1. Valve section: API 6A Forged Steel Ball Valve

API 6A:

This is a specification formulated by the American Petroleum Institute, specifically for wellhead installations and production tree equipment.

Valves that comply with API 6A standards mean that their design, materials, manufacturing and testing all meet the most stringent safety, performance and quality requirements of the oil and gas industry. It is usually applicable to extreme conditions such as high pressure, high temperature, and acidic environments containing hydrogen sulfide.

There is usually an API Monogram mark on the valve, indicating that it has been certified.

Youdaoplaceholder0 Steel:

The valve body is made of forged steel, not cast steel.

Advantages: The forging process makes the metal grains finer and the structure denser, thus having higher mechanical strength, better impact resistance and fatigue resistance. This is crucial for withstanding high pressure and pressure fluctuations.

Ball Valve

A sphere is used as the opening and closing part. Rotating it 90 degrees can achieve full opening or full closing.

Features: Low flow resistance, good sealing performance, and quick opening and closing. It is usually used to cut off or connect the medium in the pipeline (two-position switch control), and is not used for throttling.

4130

This usually refers to the valve body material conforming to the ASTM A4130 standard, which is a chromium-molybdenum alloy steel.

Features: It has high strength, high hardness, as well as excellent high-temperature resistance and corrosion resistance.

Flange:

It refers to the connection method of the valve being flange connection. This is a very strong and reliable connection method, which tightens the valve to the pipe flange through bolts and is suitable for high-pressure pipeline systems.

"FC" may refer to the end Face form of the flange, such as "Flat Face" (full plane) or the interface standard connected to the actuator.

2. Actuator section: FC Single Acting Pneumatic actuator

Youdaoplaceholder0 Actuator:

The power source is compressed air, featuring cleanliness, explosion-proof, fast response speed and easy maintenance. It is highly suitable for hazardous environments such as petroleum and chemical industries.

Single Acting:

Also known as the "spring return" type.

Working principle: There is one or more springs inside the actuator. When compressed air is introduced, the air pressure pushes the piston or diaphragm, overcoming the spring force and driving the valve to rotate (for example, to the open position). When the air pressure is cut off or disappears, the spring force will automatically reset the actuator to its original position (for example, to the off position).

Key advantage: Fail-safe mode. In the event of a loss of gas supply, the valve will automatically return to the preset safe position (normally open or normally closed), which is crucial for ensuring the safety of the process flow.

FC:

In the context of actuators, "FC" usually refers to the connection standard between the actuator and the valve, which complies with international standards such as ISO 5211, ensuring the interchangeability and installation convenience between actuators and valves of different brands.

Summary of main features

High reliability and safety: Compliant with API 6A standards, specifically designed for oil and gas wellheads to ensure safe operation under extreme working conditions.

Fail-safe design: Single-acting (spring return) structure, which can automatically return to its original position when gas supply is cut off to prevent accidents.

High-strength valve body: Made of forged chromium-molybdenum steel (A4130), it features strong pressure-bearing capacity, impact resistance and a long service life.

Quick action: Pneumatic drive, ball valve structure, achieving 90-degree rapid opening and closing.

Strong connection: Flange connection, suitable for high-pressure large-diameter pipelines.

Explosion-proof application: Pneumatic intrinsically safe, suitable for flammable and explosive environments.

Typical application fields

Wellhead equipment (production tree) for oil and gas drilling and production platforms

High-pressure oil and gas transmission pipelines

Key processes in oil refineries and chemical plants

Any high-pressure, harsh operating conditions that require fail-safe protection

Summary

Didtek 4130 Flange FC Single Acting Pneumatic Actuator API6A Forged Steel Ball Valve is an advanced automated valve solution designed for the most demanding industrial environments. It integrates forged steel ball valves that meet the highest industry standards (API 6A) and single-acting pneumatic actuators with fail-safe functions, making it a key device for ensuring safe, reliable and automated operation in the oil, gas and other high-pressure process industries.
