The 9 Types of Drill Pipe Float Valves

Drill pipe float valves are also known as non-return valves. These valves are crucial in drilling operations, mainly in the oil and gas industry. These safety devices are important as they are used to control the flow of drilling fluids to stop unwanted backflow and guarantee secure and efficient operations. With the changes in the comprehensive drilling procedures, the need for safer and specialized float valves has increased. These valves come in different types, mainly 9 types. Selecting the appropriate valve for each project is necessary. Through this blog, we will understand what drill pipe float valves are, their applications, and the types of drill pipe float valves. So let’s dive in straight. 

What are Drill Pipe Float Valves? 

A drill pipe float valve is a kind of safety equipment that is made to stop the backflow of drilling fluids into the drill pipe. It acts like a one-way door that allows liquid to go up but not come back down. This specific valve is placed near the bottom of the drill pipe and works when the pipe is moved up or down in a deep hole, which is called a wellbore. The backflow is prevented because it is dangerous to the workers and can lead to inefficiencies.

Without this valve, the liquid could flow out of control, which might cause problems like losing too much fluid or even harming the environment. So, this tool helps to keep things safe and guarantee smooth operational efficiency. 

9 Types of Drill Pipe Float Valves

Drill pipe float valves come in a range of models, and each of them is made to fulfill the precise requirements of different drilling environments and applications. Here is a comprehensive list of nine different types of float valves:

1. Model F Plunger Type Valve

The Model F Plunger Type Valve offers a quick shutoff feature. It uses a piston to offer a trustworthy and reasonable way to prevent flow-back. This model is apt for traditional drilling operations as it delivers positive shutoff during connections and constant fluid control. This type of valve is advantageous for routine operations when stopping backflow for the utmost safety and efficiency.

2. Model FA Ported Plunger Type Valve

An advanced level of the Model F is the Model FA valve, which has a ported piston that lets fluid to go through the center of the valve. It provides an additional layer of operations as it allows automatic partial filling of the drill pipe during its flow time. This valve is also a good option for more cutting-edge operations that require pressure monitoring, such as gas pressure and differential pressure monitoring.

3. Model FC Plunger Type Automatic Fill Valve

This valve has a valve stem with slots that keep the plunger open when the pipes are filling from the bottom. This saves time and reduces mess, which makes the operation more reliable and efficient. The plunger opens automatically when circulation starts and allows the fluid to flow safely. This valve is good for operations where time and efficiency are crucial aspects.

4. Model G Full Flow Flapper Type Valve

Model G Full Flow Flapper Type Valve is made for tough and challenging conditions with abrasive drilling fluids. This valve allows the fluid to flow freely. It has a quick-opening feature to stop shavings from entering the drill pipe when circulation stops. It also completely opens when the first joint is lifted, which prevents wet joints.

5. Model GA Flapper Type Valve

The Model GA Flapper Type Valve is similar to the Model G, but it has a small hole made of durable materials like carbide or tungsten-carbide. This hole allows for pressure monitoring and automatic filling of the drill pipe during run-in. It’s a better option for more complex operations.

6. Model GC Automatic Fill Flapper Type Valve

The GC Automatic Fill Flapper Valve has a key system that keeps the flapper slightly open during run-in and allows the pipe to fill from the bottom. Like the FC valve, this helps save time and prevents spills. It opens fully when the first joint is lifted and keeps operations clean and safe.

7. Model GCA Automatic Fill/Pressure Monitoring Flapper Type Valve

The GCA is a combination of the best features of the Model G, GC, and GA valves. It allows fluid to flow appropriately, monitors pressure, and also automatically fills the pipe during run-in. It is great for complex operations where both fluid control and pressure monitoring are needed.

8. Model GS – Flapper Type High Flow Wells

The GS valve is made for high-flow wells with corrosive fluids. It has a remarkable cage that maximizes flow and keeps the pressure stable. The valve is prepared to protect against wear from harsh conditions. It is also stackable, so two valves can be used together for extra versatility.

9. Model GAS – High Flow Pressure Monitoring

The GAS valve is similar to the GS but has an added wear-resistant tungsten-carbide insert. This makes it even better for high-flow and corrosive wells. It also allows for automatic filling of the drill pipe during run-in, which makes it excellent for tough drilling jobs.
